High RAM usage is one of the most common reasons a Windows 11 computer may become slow, unresponsive, or prone to application crashes. Users may notice 70%, 80%, 90%, or even 100% memory usage in Task Manager even when they believe relatively few applications are running.

However, high RAM usage does not automatically mean that Windows has a problem. Windows deliberately uses available memory for applications, caching, preloading, memory compression, drivers, and system services. Unused RAM provides little performance benefit, so Windows attempts to use available memory intelligently.

The real concern is sustained memory pressure—particularly when RAM remains close to full, available memory becomes very low, applications start paging heavily to disk, or system performance deteriorates.

This guide explains how to diagnose high RAM usage in Windows 11, identify memory-hungry applications and memory leaks, configure virtual memory correctly, troubleshoot drivers and background processes, test physical RAM, and determine when a RAM upgrade is appropriate.


1. What Is RAM?

RAM stands for Random Access Memory. It is high-speed temporary storage used by Windows and applications while the computer is operating.

RAM may contain:

  • Windows system components
  • Running applications
  • Browser tabs
  • Background services
  • Drivers
  • File cache
  • Application data
  • Memory-compressed data
  • Antivirus processes
  • Virtual machines
  • Database applications
  • Graphics-related shared memory

RAM is much faster than an SSD or HDD. Therefore, Windows attempts to keep frequently required information in RAM whenever practical.


2. Is High RAM Usage Always a Problem?

No.

For example, a computer with 16 GB RAM may show 8–10 GB in use while still operating perfectly.

What matters is not simply the percentage displayed in Task Manager.

Pay attention to:

  • Available memory
  • Committed memory
  • Paging activity
  • Application responsiveness
  • Memory usage growth over time
  • Non-paged pool size
  • Individual process consumption
  • System freezes or crashes

Typical interpretation

RAM Usage General Interpretation
Below 50% Usually comfortable
50–70% Normal for moderate workloads
70–85% May still be normal under load
85–95% Investigate if sustained
95–100% Likely memory pressure if sustained

These percentages are guidelines rather than fixed limits.

A workstation performing video editing, running virtual machines, or working with large databases can legitimately consume most available RAM.


3. Check RAM Usage Using Task Manager

Press:

Ctrl + Shift + Esc

Open:

Task Manager → Performance → Memory

Check the following information:

  • In use
  • Available
  • Committed
  • Cached
  • Paged pool
  • Non-paged pool
  • Memory speed
  • Slots used
  • Hardware reserved

For example:

15.2 / 15.8 GB RAM used

would indicate significant memory pressure on a 16 GB system.

But:

12 GB used with several GB available

may not indicate a serious problem because some memory could be reclaimable cache.


4. Find Which Application Is Consuming RAM

Open:

Task Manager → Processes

Click the Memory column to sort processes from highest to lowest usage.

Look for applications consuming unusually large amounts of memory.

Common examples include:

  • Google Chrome
  • Microsoft Edge
  • Microsoft Teams
  • Outlook
  • Adobe applications
  • Development environments
  • Database applications
  • Virtual machines
  • Games
  • Backup applications
  • Synchronization utilities
  • Antivirus software

A process consuming several gigabytes is not automatically defective. Compare its consumption with what the application is actually doing.


5. Close Unnecessary Applications

If several large programs are open simultaneously, close applications that are no longer required.

Instead of simply clicking the X button, check Task Manager because some applications continue running in the background.

Select the unnecessary process and choose:

End task

Important

Do not randomly terminate Windows system processes.

Processes such as:

  • System
  • Registry
  • Windows Logon Application
  • Local Security Authority Process
  • Service Host processes

may be essential Windows components.


6. Restart the Computer

Restarting Windows is one of the simplest methods of correcting temporary excessive memory usage.

A restart clears:

  • Application memory
  • Temporary processes
  • Certain cached states
  • Hung processes
  • Some memory leaks
  • Stuck background services

Use:

Start → Power → Restart

Do not rely exclusively on Shut down for troubleshooting because Windows Fast Startup can make shutdown/startup behavior different from a full restart.


7. Check for a Memory Leak

A memory leak occurs when a program or driver allocates memory but does not release it correctly when that memory is no longer needed.

The result may look like:

4 GB → 6 GB → 9 GB → 12 GB → 15 GB

without a corresponding increase in workload.

Typical symptoms include:

  • RAM usage continuously increases
  • Restart temporarily solves the problem
  • One process keeps growing
  • Computer becomes progressively slower
  • Application eventually crashes
  • Windows reports insufficient memory

If one application repeatedly demonstrates this behavior, update, repair, reinstall, or troubleshoot that application.


8. Use Resource Monitor

Windows includes a more detailed diagnostic utility called Resource Monitor.

Press:

Windows + R

Enter:

resmon

Open the Memory tab.

You can inspect:

  • Commit
  • Working Set
  • Shareable
  • Private memory
  • Hard faults/sec

Resource Monitor can help determine whether high memory usage is associated with specific processes and whether Windows is experiencing significant paging activity.


9. Understand Hard Faults/sec

The term Hard Fault sounds like a hardware error, but in Resource Monitor it normally does not mean your RAM is defective.

A hard fault occurs when Windows must retrieve a required memory page from disk rather than physical RAM.

Occasional hard faults are normal.

A consistently high rate combined with:

  • Very low available RAM
  • Slow application switching
  • Heavy disk activity
  • System lag

can indicate insufficient physical memory for the current workload.


10. Disable Unnecessary Startup Applications

Many programs automatically launch when Windows starts.

Open:

Task Manager → Startup apps

Review the list and disable unnecessary applications.

Possible candidates may include:

  • Chat applications
  • Game launchers
  • Vendor utilities
  • Update assistants
  • Cloud utilities you do not use
  • Third-party tray applications

Do not disable security, encryption, backup, VPN, hardware management, or business-critical software unless you understand its purpose.


11. Review Background Applications

Applications can continue consuming RAM even when their main windows are closed.

Look at:

Task Manager → Processes → Background processes

Identify applications that are unnecessary.

If an application consistently consumes excessive memory in the background, check its own settings for options such as:

  • Start with Windows
  • Continue running in background
  • Background synchronization
  • Automatic update agent
  • Preload at startup

Disable only functionality that you do not require.


12. Reduce Browser RAM Usage

Modern browsers can consume substantial amounts of RAM because individual tabs, extensions, rendering processes, GPU processes, and site isolation components may operate separately.

A browser with dozens of tabs can easily consume several gigabytes.

Google Chrome

Use Chrome's built-in Memory Saver feature where appropriate.

Also:

  • Close unused tabs
  • Remove unnecessary extensions
  • Avoid duplicate browser windows
  • Restart Chrome periodically if usage continuously grows
  • Check Chrome Task Manager for problematic tabs/extensions

Chrome Task Manager can normally be opened with:

Shift + Esc

Microsoft Edge

Edge provides resource-management features such as sleeping tabs and memory-saving controls.

Review:

Edge → Settings → System and performance

The exact names and locations of these options may change with browser updates.


13. Remove Unnecessary Browser Extensions

Extensions can consume memory even when they appear inactive.

Review:

Chrome → Extensions → Manage Extensions

or:

Edge → Extensions → Manage Extensions

Remove extensions that you no longer need.

Be especially cautious with unknown extensions that request extensive permissions.


14. Check Antimalware Service Executable

Windows Security uses the Antimalware Service Executable, commonly displayed as:

MsMpEng.exe

Temporary increases in CPU and memory consumption can occur during malware scans, signature updates, or file inspection.

If the usage is temporary, it may be normal.

Do not permanently disable Microsoft Defender merely to reduce RAM consumption.

Instead:

  • Allow active scans to complete
  • Install Windows updates
  • Update Defender security intelligence
  • Investigate whether another antivirus product is conflicting
  • Review unusually large or constantly changing folders that security software repeatedly scans

Security should not be sacrificed for a small reduction in memory usage.


15. Scan Windows for Malware

Malware, cryptominers, unwanted applications, malicious browser extensions, and compromised processes can consume system resources.

Open:

Windows Security → Virus & threat protection

Run:

Quick scan

If suspicious behavior continues, consider:

Scan options → Full scan

For serious concerns, Microsoft Defender Offline scan may also be useful.


16. Check Virtual Memory / Page File

Windows uses a paging file, commonly:

pagefile.sys

Virtual memory allows Windows to move certain memory pages between RAM and storage when appropriate.

To review its configuration:

  1. Press Windows + R
  2. Enter sysdm.cpl
  3. Open Advanced
  4. Under Performance, click Settings
  5. Open Advanced
  6. Under Virtual memory, click Change

For most systems, keeping:

Automatically manage paging file size for all drives

enabled is the safest configuration.


17. Should You Disable the Page File if You Have Lots of RAM?

Generally, no.

Even computers with 16 GB, 32 GB, 64 GB, or more RAM can benefit from having a paging file.

Some applications and Windows components expect virtual memory to be available.

Disabling the page file can cause:

  • Out-of-memory errors
  • Application crashes
  • Reduced commit limit
  • Problems with certain crash dumps
  • Instability during workload spikes

For most users, use a System managed size rather than disabling virtual memory.


18. Check Committed Memory

Task Manager displays values similar to:

Committed: 18.5 / 31.7 GB

The first number represents the current committed virtual memory.

The second represents the commit limit.

If the first value approaches the second, Windows may be running dangerously close to its available commit capacity.

This can eventually produce:

  • Out-of-memory errors
  • Application crashes
  • Failed application launches
  • Severe performance problems

Increasing physical RAM and ensuring a properly configured page file can help, depending on the cause.


19. Check Non-Paged Pool Memory

In:

Task Manager → Performance → Memory

look at:

Non-paged pool

The non-paged pool contains kernel memory that must remain in physical RAM.

If this value becomes abnormally large and continuously grows, a faulty or leaking device driver may be responsible.

Possible sources include:

  • Network drivers
  • Storage drivers
  • VPN software
  • Antivirus drivers
  • Printer drivers
  • Backup software
  • Virtualization software
  • Hardware monitoring tools

This type of problem requires deeper investigation rather than simply closing applications.


20. Update Device Drivers

Outdated or defective drivers can create memory leaks.

Prioritize drivers for:

  • Graphics
  • Network adapters
  • Wi-Fi
  • Storage controllers
  • Chipset
  • Bluetooth
  • Audio
  • Docking stations

Prefer drivers from:

  • Windows Update
  • Computer manufacturer
  • Motherboard manufacturer
  • Hardware manufacturer

Avoid unknown third-party "automatic driver updater" utilities.


21. Install Windows Updates

Microsoft regularly releases fixes for Windows stability, compatibility, security, and performance.

Open:

Settings → Windows Update

Select:

Check for updates

Install appropriate updates and restart the computer.

If excessive RAM usage began immediately after a particular update, investigate that update specifically rather than assuming all high memory usage is caused by Windows itself.


22. Perform a Clean Boot

A clean boot can help determine whether third-party services or startup programs are causing excessive memory usage.

Press:

Windows + R

Enter:

msconfig

Under Services:

  1. Select Hide all Microsoft services
  2. Click Disable all

Then disable third-party startup applications through Task Manager and restart.

Important

This procedure is for troubleshooting.

If the problem disappears after a clean boot, re-enable services and startup items gradually until the problematic software is identified.

Be careful on business computers where backup, security, VPN, database, licensing, or remote-support services may be required.


23. Repair Windows System Files

Corrupted Windows system components can sometimes contribute to abnormal system behavior.

Open Terminal or Command Prompt as Administrator.

Run:

DISM /Online /Cleanup-Image /RestoreHealth

After DISM completes, run:

sfc /scannow

Restart Windows after the repair process.

These commands should not be treated as generic RAM-cleaning commands. They are useful when system-file corruption is suspected.


24. Check RAM Hardware

High memory usage is usually a software/workload issue rather than defective RAM. However, faulty memory can cause instability, crashes, corrupted data, and blue-screen errors.

Press:

Windows + R

Enter:

mdsched.exe

Choose:

Restart now and check for problems

Windows will restart and run Windows Memory Diagnostic.

For more extensive hardware testing, specialized bootable memory-testing tools may be used.


25. Check Whether Windows Detects All Installed RAM

Open:

Task Manager → Performance → Memory

Verify that Windows detects the expected capacity.

For example:

Installed physically:

16 GB

Windows should normally report approximately 16 GB, although some amount may be hardware reserved.

If significantly less RAM is usable, investigate:

  • Incorrectly seated RAM
  • BIOS/UEFI settings
  • Incompatible modules
  • Hardware reserved memory
  • Faulty RAM slot
  • Integrated graphics reservation
  • Motherboard limitations

26. Understand Hardware Reserved Memory

Task Manager may display:

Hardware reserved: 500 MB

or possibly several gigabytes.

Some reserved memory is normal, particularly on systems using integrated graphics.

However, an unexpectedly large amount can warrant investigation.

Check:

  • BIOS/UEFI settings
  • RAM installation
  • Integrated GPU memory allocation
  • Motherboard documentation
  • RAM module compatibility

Do not modify unfamiliar BIOS memory settings without understanding their purpose.


27. Check SysMain Only When Troubleshooting

The SysMain service, historically associated with Superfetch functionality, helps Windows optimize application loading.

It is sometimes blamed for high resource usage.

Do not permanently disable SysMain merely because it appears in a generic optimization guide.

If troubleshooting strongly suggests SysMain is responsible, temporarily stop it and compare system behavior.

Press:

Windows + R

Enter:

services.msc

Locate:

SysMain

Test the system before and after stopping the service.

If there is no meaningful improvement, restore the normal configuration.


28. Avoid RAM Cleaner Applications

Many so-called RAM optimizer or memory cleaner applications promise to "free" large amounts of RAM.

These tools can be misleading.

Some simply force applications or cached data out of physical RAM, after which Windows may need to reload that data again.

This can actually reduce performance.

Windows already includes sophisticated memory management.

Instead of repeatedly "cleaning RAM," identify the process, service, driver, workload, or configuration responsible for genuine memory pressure.


29. Use Performance Monitor for Advanced Diagnosis

Advanced administrators can use:

perfmon

Useful counters include:

Memory → Available MBytes

Memory → Committed Bytes

Memory → Commit Limit

Memory → Pages/sec

Memory → Pool Nonpaged Bytes

Process → Private Bytes

Performance Monitor is especially useful when the problem develops slowly over several hours or days.

For example, continuously increasing Private Bytes for one application can help identify a memory leak.


30. Use Process Explorer for Deeper Investigation

For advanced troubleshooting, Microsoft's Sysinternals Process Explorer can provide more detailed process information than Task Manager.

It can help administrators investigate:

  • Process hierarchy
  • Private bytes
  • Working set
  • Loaded modules
  • Handles
  • Process ownership
  • Application behavior

This is particularly useful when Task Manager does not provide enough information to identify the source of excessive memory consumption.


31. RAM Usage Is High but No Process Uses Much Memory

This is an important scenario.

Suppose Task Manager reports:

15 GB of 16 GB RAM used

but no visible application appears to account for the missing memory.

Possible explanations include:

  • Kernel memory
  • Driver memory leak
  • Non-paged pool growth
  • File cache
  • Memory compression
  • Virtualization
  • Shared GPU memory
  • Background services
  • System components

In such cases, do not simply add together the Memory column in Task Manager and assume the remaining RAM is "missing."

Investigate the Performance → Memory section, Resource Monitor, pool usage, and advanced diagnostic tools.


32. Windows Memory Compression

Windows can compress less-active memory pages rather than immediately writing them to disk.

This reduces paging and can improve performance.

Therefore, seeing memory compression activity does not necessarily indicate a problem.

Do not disable memory compression simply because RAM usage appears high unless you have a specific diagnostic reason.


33. Restart Problematic Applications Periodically

Some long-running applications gradually accumulate memory due to caching or memory-management problems.

Examples can include:

  • Browsers
  • Development tools
  • Database clients
  • Accounting software
  • Graphics applications
  • Communication software

If restarting one application immediately releases several gigabytes of RAM, investigate whether that application requires an update, repair, configuration change, or reinstall.


34. Reinstall a Problematic Application

If one program consistently causes excessive RAM usage:

  1. Update the application.
  2. Disable unnecessary plugins/extensions.
  3. Reset its configuration if appropriate.
  4. Repair the installation.
  5. Uninstall it.
  6. Restart Windows.
  7. Install the latest supported version.

Back up application data and configuration before reinstalling business-critical software.


35. How Much RAM Does Windows 11 Need?

The amount of RAM required depends far more on workload than on Windows alone.

8 GB

Suitable for relatively light usage such as:

  • Web browsing
  • Office applications
  • Email
  • Basic business applications

Heavy multitasking may create memory pressure.

16 GB

A practical capacity for many mainstream users performing:

  • Office work
  • Multiple browser tabs
  • Accounting software
  • General multitasking
  • Light development
  • Typical business workloads

32 GB

Useful for:

  • Heavy multitasking
  • Software development
  • Large spreadsheets
  • Content creation
  • Virtual machines
  • Larger datasets
  • Professional applications

64 GB or more

May be appropriate for:

  • Multiple virtual machines
  • Large databases
  • Engineering workloads
  • Professional media production
  • Large development environments
  • Specialized scientific workloads

Adding RAM will not solve a defective application or driver memory leak, but it can significantly improve performance when the workload genuinely requires more physical memory.


36. When Should You Upgrade RAM?

Consider upgrading RAM when all or most of the following are true:

  • Memory usage regularly exceeds 85–90%
  • Available RAM frequently becomes very low
  • Heavy paging occurs during normal work
  • Applications become slow when multitasking
  • Closing applications immediately improves performance
  • No abnormal memory leak is found
  • Current workload genuinely exceeds installed capacity

For example, if an 8 GB system routinely consumes almost all physical memory while running normal business applications, upgrading to 16 GB can provide a substantial improvement.


37. Before Buying RAM, Check Compatibility

Before purchasing memory, verify:

  • DDR generation
  • DDR4 vs DDR5
  • Desktop DIMM vs laptop SO-DIMM
  • Supported memory speed
  • Maximum motherboard capacity
  • Maximum capacity per slot
  • Number of available slots
  • CPU memory support
  • ECC vs non-ECC requirements where applicable

Do not purchase RAM based solely on capacity.


38. Advanced Diagnostic Sequence

For persistent high RAM usage, use this troubleshooting sequence:

Step 1: Restart Windows.

Step 2: Check Task Manager → Performance → Memory.

Step 3: Sort Task Manager processes by Memory.

Step 4: Check Resource Monitor.

Step 5: Observe whether memory usage continuously increases.

Step 6: Check startup applications.

Step 7: Review browser tabs and extensions.

Step 8: Scan for malware.

Step 9: Verify page-file configuration.

Step 10: Check committed memory.

Step 11: Check paged and non-paged pool values.

Step 12: Update Windows.

Step 13: Update relevant hardware drivers.

Step 14: Perform a clean boot.

Step 15: Run DISM and SFC if corruption is suspected.

Step 16: Test physical RAM if crashes or hardware symptoms exist.

Step 17: Use Performance Monitor or advanced Sysinternals tools if the source remains unidentified.

Step 18: Upgrade RAM if the installed capacity is genuinely insufficient.


39. Example Troubleshooting Scenario

Consider a Windows 11 computer with:

RAM: 16 GB

Task Manager shows:

Memory usage: 94%

The largest processes are:

  • Chrome: 4.2 GB
  • Teams: 1.4 GB
  • Outlook: 1.1 GB
  • Accounting application: 2.0 GB
  • Antivirus and background services: additional usage

In this situation, Windows may simply be running a workload close to the machine's physical-memory capacity.

Possible solutions include:

  • Close unused Chrome tabs
  • Enable browser memory-saving features
  • Remove unnecessary extensions
  • Disable unnecessary startup programs
  • Close applications that are not currently required
  • Verify the page file is system-managed
  • Consider upgrading from 16 GB to 32 GB if this is the user's normal workload

The solution is different from a memory leak.


40. Example of a Memory Leak

Suppose an application uses:

9:00 AM — 500 MB

11:00 AM — 1.5 GB

1:00 PM — 3 GB

3:00 PM — 6 GB

while performing approximately the same workload.

Closing and reopening the application returns usage to 500 MB.

This pattern strongly suggests that the application deserves investigation for a possible memory leak.

The next steps would include:

  • Update the application
  • Check plugins
  • Review vendor documentation
  • Repair/reinstall it
  • Contact the application vendor if necessary

Adding RAM alone would merely delay the eventual problem if the application continues consuming memory indefinitely.


Frequently Asked Questions – FAQ

1. Why is Windows 11 using so much RAM?

Windows uses RAM for applications, services, caching, drivers, memory compression, security software, and other operating-system functions. High usage becomes concerning primarily when it causes sustained memory pressure or performance problems.

2. Is 80% RAM usage bad?

Not necessarily. If the computer remains responsive and the workload justifies the usage, 80% can be acceptable. Sustained usage above roughly 85–90% deserves closer examination, especially if available memory is low.

3. Is 100% RAM usage dangerous?

It normally does not physically damage RAM, but sustained near-100% usage can cause severe paging, application slowdowns, crashes, or out-of-memory errors.

4. Why is my RAM usage high when nothing is open?

Background applications, services, drivers, antivirus software, caching, memory compression, kernel memory, and startup programs can consume RAM even when no application windows are visible.

5. How do I find which program is using the most RAM?

Open:

Task Manager → Processes

and sort by the Memory column.

6. How can I reduce Chrome RAM usage?

Close unnecessary tabs, remove unused extensions, use Chrome's memory-saving features, and use Chrome Task Manager to identify memory-heavy tabs or extensions.

7. Should I use a RAM cleaner?

Generally, no. Windows manages physical memory automatically, and many RAM-cleaning applications simply force useful cached information out of memory.

8. Should I disable virtual memory?

Usually no. A system-managed page file is recommended for most Windows 11 computers.

9. Does increasing virtual memory increase physical RAM?

No. Virtual memory uses storage and is substantially slower than physical RAM.

10. Will adding more RAM make Windows faster?

It can if insufficient RAM is causing heavy paging or limiting your normal workload. It will not necessarily fix software bugs, memory leaks, malware, or driver problems.

11. Is 8 GB RAM enough for Windows 11?

It can be sufficient for light workloads, but multitasking with browsers and modern business applications can quickly consume most of it. 16 GB is more comfortable for many users.

12. Is 16 GB RAM enough for Windows 11?

For many users, yes. Heavy multitasking, development, virtual machines, media production, or large professional applications may benefit from 32 GB or more.

13. Why does RAM usage keep increasing?

A continuously increasing value can indicate an application or driver memory leak, although workload changes and caching should also be considered.

14. What is a Windows memory leak?

It occurs when software allocates memory and fails to release it properly after the memory is no longer required.

15. Can drivers cause high RAM usage?

Yes. Faulty drivers can cause kernel or non-paged pool memory leaks.

16. What is non-paged pool memory?

It is kernel memory that must remain in physical RAM and cannot simply be paged out to disk. Abnormally increasing non-paged pool usage can indicate a driver-related problem.

17. Does Windows Defender use RAM?

Yes. Antivirus scanning requires CPU and memory resources. Temporary increases during scans are normal.

18. Should I disable Windows Defender to save RAM?

No. Permanently disabling security merely to reduce RAM usage is generally not recommended.

19. Can malware cause high RAM usage?

Yes. Malware, unwanted software, cryptominers, malicious extensions, and compromised processes can consume significant system resources.

20. Does restarting Windows clear RAM?

A restart terminates running processes and clears volatile memory, making it useful for temporarily resolving memory leaks or stuck processes.

21. Why does high RAM usage make the computer slow?

When physical RAM becomes scarce, Windows may need to rely more heavily on storage-backed virtual memory. Storage is much slower than RAM, so excessive paging can noticeably reduce performance.

22. Can Windows Update fix high memory usage?

Yes, when the issue is caused by a known Windows bug or compatibility problem. Application and driver updates can be equally important.

23. What does Committed memory mean?

Committed memory represents virtual memory that Windows has promised to processes and that must be backed by either physical RAM or the page file.

24. What are hard faults in Resource Monitor?

They indicate that Windows had to retrieve a memory page from storage rather than physical RAM. They do not automatically indicate defective hardware.

25. How do I know whether I need more RAM?

If your normal workload repeatedly fills physical memory, available RAM becomes very low, paging is heavy, and no memory leak or abnormal process is responsible, additional RAM may be appropriate.


Conclusion

High RAM usage in Windows 11 should be diagnosed rather than automatically treated as a fault. Modern Windows intentionally uses available memory for applications, caching, security, drivers, and performance optimization.

The most important question is:

Is the computer experiencing genuine memory pressure, or is Windows simply making productive use of available RAM?

Start with Task Manager, identify memory-intensive processes, check Available and Committed memory, inspect Resource Monitor, and determine whether usage is stable or continuously increasing.

If RAM usage continuously rises, investigate application or driver memory leaks. If the computer's normal workload genuinely requires nearly all installed physical memory, upgrading RAM may be the correct long-term solution.

Avoid blindly disabling Windows services, security software, memory compression, or the paging file. Such changes can create additional problems without addressing the actual cause.

A systematic diagnosis—processes → applications → startup items → browser → malware → page file → drivers → memory pools → hardware → RAM capacity—is the safest and most effective way to troubleshoot high RAM usage in Windows 11.
