msedgewebview2.exe High Memory Usage: How to Fix WebView2 High RAM & CPU in Windows 11/10

If Task Manager shows several msedgewebview2.exe processes consuming hundreds of megabytes—or even several gigabytes—of RAM, don't immediately delete, disable or repeatedly kill them.

msedgewebview2.exe belongs to Microsoft Edge WebView2 Runtime, a Microsoft component that allows Windows applications to display web-based content inside normal desktop applications.

The most important point is:

High msedgewebview2.exe memory usage is often caused by the application using WebView2 rather than by WebView2 itself.

Therefore, the correct troubleshooting process is:

Verify the process → Check total memory usage → Identify the application using WebView2 → Restart/update that application → Check WebView2 Runtime → Monitor whether memory continues growing.

This guide covers Windows 10, Windows 11, Windows Server, Remote Desktop Services (RDS), Terminal Server and other multi-user environments.

Quick Fix: msedgewebview2.exe Using Too Much Memory

If you need a quick troubleshooting sequence, start here:

1. Open Task Manager → Performance → Memory and confirm Windows is actually under memory pressure.
2. Check how many msedgewebview2.exe processes are running.
3. Identify which application is using WebView2.
4. Save your work.
5. Completely close that application.
6. Wait 10–20 seconds.
7. Check whether its WebView2 processes disappear.
8. Reopen the application.
9. Monitor RAM and CPU again.
10. Update the affected application.
11. Update Windows and Microsoft Edge/WebView2 components.
12. If the problem returns, monitor WebView2 memory over time.

Do not uninstall WebView2 simply to reduce RAM usage.

Many Windows and third-party applications depend on it.

What Is msedgewebview2.exe?

msedgewebview2.exe is an executable belonging to the Microsoft Edge WebView2 Runtime.

WebView2 allows software developers to embed web technologies such as:

• HTML;
• CSS;
• JavaScript;
• web applications;
• authentication pages;
• dashboards;
• online services;

inside ordinary Windows desktop applications.

In simplified form:

Windows Application
↓
WebView2 Control
↓
Microsoft Edge WebView2 Runtime
↓
Chromium Rendering Engine
↓
HTML / CSS / JavaScript / Web Services

This allows a Windows application to display modern web-based interfaces without requiring the user to manually open Microsoft Edge.

Why Is msedgewebview2.exe Running When Microsoft Edge Is Closed?

Because WebView2 is not the same thing as having the Microsoft Edge browser open.

Another Windows application may be using the Edge WebView2 Runtime internally.

Microsoft lists applications and Windows experiences such as:

• Microsoft Teams;
• Microsoft Office;
• Outlook;
• Windows Widgets;
• Weather;
• other Microsoft applications;
• third-party applications;

as examples of software that can use WebView2.

Therefore:

Microsoft Edge does not need to be visibly open for msedgewebview2.exe to appear in Task Manager.

Is msedgewebview2.exe a Virus?

Normally, no.

The genuine msedgewebview2.exe is a legitimate Microsoft component.

However:

Never determine whether a process is genuine from its filename alone.

Malware can use filenames resembling legitimate Microsoft processes.

How to Check Whether msedgewebview2.exe Is Genuine

Step 1: Open Task Manager

Press:

Ctrl + Shift + Esc

Step 2: Locate WebView2

Look under Processes or Details for:

msedgewebview2.exe

or:

Microsoft Edge WebView2

Step 3: Open the File Location

Right-click the process and select:

Open file location

A legitimate executable should be associated with a Microsoft Edge/WebView2 Runtime installation.

Step 4: Check the Digital Signature

Right-click:

msedgewebview2.exe

Select:

Properties → Digital Signatures

Verify that the executable has a valid Microsoft digital signature.

Step 5: Scan If Necessary

If you remain suspicious, scan the file using:

• Microsoft Defender;
• your organization's endpoint-security software;
• another trusted security product.

Warning Signs

Investigate further if a file named msedgewebview2.exe is unexpectedly running from locations such as:

C:\Temp\

or:

C:\Users\<username>\Downloads\

or another unrelated/suspicious folder.

Why Are So Many msedgewebview2.exe Processes Running?

Seeing multiple WebView2 processes is normally expected.

Microsoft WebView2 follows the multi-process architecture used by Microsoft Edge and Chromium.

A WebView2 process group can contain:

• browser process;
• renderer processes;
• GPU process;
• network/utility processes;
• audio-related processes;
• other helper processes.

Therefore Task Manager may display:

msedgewebview2.exe
msedgewebview2.exe
msedgewebview2.exe
msedgewebview2.exe
msedgewebview2.exe

even when they are associated with one application.

Different applications can also create separate WebView2 process groups.

Therefore:

10 WebView2 processes do not necessarily mean 10 applications are running.

Why Does Microsoft Edge WebView2 Use So Much RAM?

WebView2 is effectively running web content inside another Windows application.

Memory can be required for:

• HTML rendering;
• CSS;
• JavaScript;
• images;
• dashboards;
• authentication pages;
• web APIs;
• video;
• audio;
• GPU acceleration;
• network operations;
• cached content;
• renderer processes;
• multiple WebView2 controls.

The amount of RAM required therefore depends heavily on the application hosting WebView2.

A simple sign-in screen may require relatively little memory.

A complex business application containing:

• several dashboards;
• large JavaScript applications;
• embedded services;
• multiple WebView2 controls;
• constantly refreshing data;

may consume considerably more.

Is High WebView2 Memory Usage Always a Problem?

No.

A large number displayed next to one process does not automatically mean Windows is running out of memory.

First check:

Task Manager → Performance → Memory

Review:

• Installed;
• In use;
• Available;
• Committed;
• Cached;
• Paged pool;
• Non-paged pool.

For example:

Installed RAM: 16 GB
In use: 15 GB
Available: 450 MB

This indicates genuine memory pressure.

But:

Installed RAM: 32 GB
In use: 12 GB
Available: 19 GB

means Windows still has substantial available memory.

The second situation may not require aggressive optimization simply because one WebView2 process appears large.

Is High WebView2 RAM Usage a Memory Leak?

Not necessarily.

Suppose Task Manager shows:

Process	RAM
msedgewebview2.exe	420 MB
msedgewebview2.exe	260 MB
msedgewebview2.exe	170 MB
msedgewebview2.exe	110 MB
Total	960 MB

That total alone does not prove a memory leak.

A possible leak or resource-management problem becomes more likely if:

• RAM usage continuously increases for hours;
• the host application is idle but memory keeps increasing;
• closing the host application does not release its processes/resources appropriately;
• the same application repeatedly produces abnormal WebView2 growth;
• available Windows memory becomes critically low;
• restarting the application temporarily fixes the problem;
• abnormal consumption returns after several hours or days.

Memory trend is more useful than a single Task Manager screenshot.

Step 1: Calculate Total WebView2 RAM Usage

Looking at one WebView2 process can be misleading.

Open PowerShell and run:

Get-Process msedgewebview2 -ErrorAction SilentlyContinue |
Select-Object Id, ProcessName, CPU,
@{Name="RAM_MB";Expression={[math]::Round($_.WorkingSet64/1MB,2)}},
StartTime |
Sort-Object RAM_MB -Descending

This displays:

• Process ID;
• process name;
• CPU usage;
• RAM usage;
• start time.

Step 2: Calculate Combined msedgewebview2.exe Memory

Use:

$wv = Get-Process msedgewebview2 -ErrorAction SilentlyContinue

if ($wv) {
    [PSCustomObject]@{
        Processes  = $wv.Count
        TotalRAM_MB = [math]::Round(
            ($wv | Measure-Object WorkingSet64 -Sum).Sum / 1MB, 2
        )
    }
}

Example:

Processes    TotalRAM_MB
---------    -----------
14           1842.65

This tells you that all currently detected WebView2 processes together are consuming approximately 1.84 GB of working-set memory.

That is more useful than looking at a single process.

Step 3: Find Which Application Is Using msedgewebview2.exe

This is one of the most important steps in the entire troubleshooting process.

Do not immediately kill every WebView2 process.

First determine which application is creating them.

Run:

Get-CimInstance Win32_Process |
Where-Object {$_.Name -eq "msedgewebview2.exe"} |
Select-Object ProcessId, ParentProcessId, CommandLine

The ParentProcessId can provide an important clue.

Then inspect running processes with:

Get-CimInstance Win32_Process |
Select-Object ProcessId, ParentProcessId, Name, ExecutablePath

For a particular parent PID:

Get-CimInstance Win32_Process -Filter "ProcessId=1234" |
Select-Object Name, ProcessId, ExecutablePath, CommandLine

Replace 1234 with the relevant Parent Process ID.

Why Finding the Host Application Matters

Suppose you discover that a particular business application is generating the WebView2 processes.

That application might be:

• creating unnecessary WebView2 instances;
• keeping hidden windows active;
• running heavy JavaScript;
• loading multiple dashboards;
• constantly refreshing web content;
• failing to release unused WebView2 controls;
• experiencing its own memory leak.

Therefore:

High WebView2 memory can be the symptom while the host application is the actual cause.

This distinction is critical.

Step 4: Restart the Application Using WebView2

After identifying the likely host application:

1. Save all work.
2. Completely close the application.
3. Wait approximately 10–20 seconds.
4. Check Task Manager.
5. See whether its WebView2 processes disappear.
6. Reopen the application.
7. Monitor RAM and CPU usage.

If memory drops substantially when that application closes, you have established an important relationship between the application and the WebView2 workload.

Step 5: Update the Host Application

If one application repeatedly causes abnormal WebView2 usage, update that application.

Also consider updating:

• Windows;
• Microsoft 365 applications;
• Microsoft Edge;
• Microsoft Edge WebView2 Runtime;
• related application components.

A WebView2 resource problem can originate from the application's implementation rather than from the Runtime itself.

Step 6: Can I End msedgewebview2.exe?

Yes, but it should normally be treated as a temporary troubleshooting or recovery action, not a permanent solution.

Using Command Prompt

taskkill /F /IM msedgewebview2.exe

Using PowerShell

Stop-Process -Name msedgewebview2 -Force

Warning

This can terminate WebView2 processes being used by active applications.

Those applications may:

• show blank windows;
• lose embedded content;
• refresh;
• stop responding correctly;
• automatically restart WebView2;
• require restarting.

Save your work before terminating WebView2 processes.

On an RDS server, do not run a global termination command casually because it may affect several users simultaneously.

Why Does msedgewebview2.exe Come Back After I End It?

This is usually normal.

The sequence may be:

Application running
↓
Application needs WebView2
↓
Application launches WebView2
↓
User kills msedgewebview2.exe
↓
Application still needs WebView2
↓
WebView2 starts again

Therefore:

Repeatedly killing msedgewebview2.exe does not fix the underlying cause.

You need to identify the application launching it.

Step 7: Update or Repair Microsoft Edge WebView2 Runtime

If WebView2 itself appears damaged, or applications display:

• blank windows;
• white screens;
• crashes;
• initialization errors;
• missing embedded content;

update or repair the WebView2 Runtime.

Use Microsoft's official WebView2 Evergreen Runtime distribution rather than downloading installers from unknown third-party websites.

The Evergreen distribution model is designed to keep the Runtime updated with current WebView2 platform improvements.

After updating:

1. Close affected applications.
2. Install/update the Runtime.
3. Restart Windows if required.
4. Reopen the application.
5. Monitor CPU and RAM again.

Should I Uninstall Microsoft Edge WebView2 Runtime?

Usually no.

Many modern Windows and third-party applications depend on WebView2.

Removing it can cause:

• applications not opening;
• blank application windows;
• missing dashboards;
• authentication failures;
• missing embedded content;
• broken application features;
• applications reinstalling WebView2.

Uninstalling WebView2 is therefore not recommended as a routine RAM optimization method.

Should I Permanently Disable msedgewebview2.exe?

Generally, no.

Avoid blindly blocking WebView2 using:

• AppLocker;
• Software Restriction Policies;
• file permissions;
• firewall rules;
• antivirus blocks;
• renaming the executable;
• deleting the executable.

Applications that legitimately depend on WebView2 may stop functioning.

The better objective is:

Find the application producing excessive WebView2 usage and troubleshoot that application.

Step 8: Check Windows Commit Memory

Physical RAM is only part of Windows memory management.

Open:

Task Manager → Performance → Memory

Check:

Committed

You can also use PowerShell:

Get-CimInstance Win32_OperatingSystem |
Select-Object `
@{N="TotalRAM_GB";E={[math]::Round($_.TotalVisibleMemorySize/1MB,2)}},
@{N="FreeRAM_GB";E={[math]::Round($_.FreePhysicalMemory/1MB,2)}},
@{N="TotalVirtual_GB";E={[math]::Round($_.TotalVirtualMemorySize/1MB,2)}},
@{N="FreeVirtual_GB";E={[math]::Round($_.FreeVirtualMemory/1MB,2)}}

If committed memory approaches the commit limit, applications can experience failures even when you are focusing only on physical RAM.

Step 9: Check the Top RAM-Consuming Processes

Do not troubleshoot WebView2 in isolation.

Run:

Get-Process |
Sort-Object WorkingSet64 -Descending |
Select-Object -First 20 `
ProcessName,
Id,
@{N="RAM_MB";E={[math]::Round($_.WorkingSet64/1MB,2)}},
CPU

You may discover that the largest memory consumers are actually:

• Chrome;
• Microsoft Edge;
• Outlook;
• Teams;
• SQL Server;
• Java applications;
• accounting/business applications;
• WebView2;
• other software.

The objective is to understand total system memory pressure.

msedgewebview2.exe High Memory on RDS / Remote Desktop Servers

WebView2 deserves special attention on Windows Remote Desktop Session Hosts.

Imagine an RDS server with:

• 20 concurrent users;
• Outlook;
• Microsoft 365;
• browsers;
• accounting software;
• business applications;
• WebView2-based software.

Each user may generate their own WebView2 workload.

For example:

User01    WebView2    450 MB
User02    WebView2    780 MB
User03    WebView2    520 MB
User04    WebView2    920 MB
...

Even acceptable per-user consumption can become substantial when multiplied across 20, 30 or more sessions.

Therefore:

On RDS, calculate WebView2 usage per user and in aggregate.

Check WebView2 RAM Usage by RDS User

Run PowerShell as Administrator:

Get-Process msedgewebview2 -IncludeUserName -ErrorAction SilentlyContinue |
Select-Object UserName, Id,
@{N="RAM_MB";E={[math]::Round($_.WorkingSet64/1MB,2)}},
CPU, StartTime |
Sort-Object UserName, RAM_MB -Descending

This can help identify which user sessions are generating the largest WebView2 workloads.

Calculate Total WebView2 RAM Per RDS User

Use:

Get-Process msedgewebview2 -IncludeUserName -ErrorAction SilentlyContinue |
Group-Object UserName |
ForEach-Object {

    $total = ($_.Group |
        Measure-Object WorkingSet64 -Sum).Sum

    [PSCustomObject]@{
        User      = $_.Name
        Processes = $_.Count
        RAM_MB    = [math]::Round($total / 1MB,2)
    }

} | Sort-Object RAM_MB -Descending

Example:

User              Processes    RAM_MB
----              ---------    ------
DOMAIN\User01     12           1540
DOMAIN\User07     10           1210
DOMAIN\User15      8            890

This is particularly useful on heavily used RDS Session Hosts.

Do Not Globally Kill WebView2 on a Production RDS Server

Running:

taskkill /F /IM msedgewebview2.exe

on a production Remote Desktop server can affect multiple users.

Instead:

1. Identify the affected user.
2. Determine which application is generating the workload.
3. Ask the user to save their work.
4. Restart only the affected application where possible.
5. Restart the user's session if necessary.
6. Use server-wide termination only when you understand the impact.

Step 10: Monitor WebView2 Memory Over Time

A single reading does not prove a memory leak.

You can log combined WebView2 working-set memory:

$Processes = Get-Process msedgewebview2 -ErrorAction SilentlyContinue

if ($Processes) {

    $TotalMB = [math]::Round(
        ($Processes |
        Measure-Object WorkingSet64 -Sum).Sum / 1MB,2
    )

    "$((Get-Date).ToString('yyyy-MM-dd HH:mm:ss')),$($Processes.Count),$TotalMB" |
    Out-File "C:\WebView2-Memory.csv" -Append
}

Example:

2026-08-30 09:00:00,8,620
2026-08-30 10:00:00,9,790
2026-08-30 11:00:00,9,1100
2026-08-30 12:00:00,10,1510
2026-08-30 13:00:00,10,1980

If memory repeatedly grows while workload remains relatively stable, further investigation is justified.

Step 11: Check Event Viewer

Press:

Win + R

Enter:

eventvwr.msc

Open:

Windows Logs → Application

Look for errors occurring around the same time as the WebView2 problem.

Useful information includes:

• faulting application name;
• faulting module;
• exception code;
• application crash;
• Runtime failure;
• repeated host-application errors.

If one specific application repeatedly produces errors together with WebView2 problems, that information can be useful when escalating the issue to the software vendor.

WebView2 Shows a Blank or White Screen

If the problem is a blank embedded application window rather than high RAM usage, investigate:

• WebView2 Runtime problems;
• renderer failure;
• GPU process problems;
• endpoint-security interference;
• application-control policies;
• application corruption;
• damaged application user data;
• host-application problems.

If WebView2 child processes appear briefly and immediately disappear, security/application-control interaction may deserve investigation.

Do not permanently disable antivirus or endpoint security simply to make WebView2 work.

Should I Clear the WebView2 Cache?

Sometimes, but not as a general RAM fix.

WebView2 user-data folders can contain:

• cookies;
• cached files;
• authentication information;
• permissions;
• application state;
• other browser-related data.

Blindly deleting them can:

• sign users out;
• reset application settings;
• remove cached data;
• cause new authentication problems.

Clear application-specific WebView2 data only when there is a valid troubleshooting reason and preferably according to the software vendor's documented procedure.

Developer Note: Reducing WebView2 Memory Usage

If you develop an application using WebView2, memory optimization should primarily happen at the application level.

Microsoft recommends practices such as:

• sharing/reusing WebView2 environments where appropriate;
• avoiding unnecessary WebView2 instances;
• managing process lifetime correctly;
• reducing unnecessarily complex web content;
• avoiding inefficient long-running JavaScript;
• monitoring renderer processes;
• managing user-data folders carefully;
• testing memory consumption during long-running sessions.

Microsoft's current WebView2 guidance specifically notes that creating more WebView2 controls and process groups increases resource overhead.

Therefore, developers should optimize how their application uses WebView2, rather than expecting the end user to kill WebView2 processes manually.

WebView2 High RAM Troubleshooting Checklist

Use this order:

1. Verify the Executable

Confirm msedgewebview2.exe is Microsoft-signed and associated with an expected WebView2 installation.

2. Check Overall Windows Memory

Determine whether the computer is actually under RAM or commit pressure.

3. Calculate Total WebView2 Usage

Do not judge the situation from one process.

4. Identify the Host Application

Find which application is creating the WebView2 workload.

5. Restart Only That Application

Avoid terminating unrelated WebView2 processes.

6. Monitor Memory Over Time

Determine whether consumption is stable or continuously increasing.

7. Update the Host Application

The application itself may contain the resource-management problem.

8. Update WebView2 Runtime

Use Microsoft's official WebView2 distribution.

9. Check Event Viewer

Look for repeatable host-application or Runtime crashes.

10. Check Security Software Interaction

Investigate antivirus, EDR and application-control interaction when WebView2 processes fail to start correctly.

11. Check RDS Usage Per User

On multi-user servers, calculate aggregate WebView2 consumption across sessions.

12. Escalate to the Application Vendor

If one particular application repeatedly produces abnormal WebView2 resource growth, the application's vendor may need to investigate.

Common Mistakes to Avoid

Mistake 1: Assuming msedgewebview2.exe Is Malware

The filename normally belongs to Microsoft's WebView2 Runtime.

Verify the executable rather than deleting it.

Mistake 2: Killing Every WebView2 Process

This may break applications currently using WebView2.

Mistake 3: Uninstalling WebView2 to Save RAM

Applications depending on it may stop functioning.

Mistake 4: Assuming Multiple Processes Mean Something Is Wrong

Multiple processes are normal for WebView2's Chromium-based architecture.

Mistake 5: Looking Only at Physical RAM

Windows commit usage and the pagefile also matter.

Mistake 6: Ignoring the Host Application

The application embedding WebView2 is often the most important part of the investigation.

Mistake 7: Calling Every High-Memory Situation a Memory Leak

A genuine memory leak requires evidence of abnormal resource growth over time.

Frequently Asked Questions (FAQ)

1. What is msedgewebview2.exe?

msedgewebview2.exe belongs to Microsoft Edge WebView2 Runtime. It enables Windows applications to embed web technologies such as HTML, CSS and JavaScript.

2. Is msedgewebview2.exe malware?

Normally, no. The genuine executable is a Microsoft component. Verify its location and Microsoft digital signature if you suspect malware.

3. Why is msedgewebview2.exe running when Microsoft Edge is closed?

Because another Windows application can use WebView2 independently of the visible Microsoft Edge browser.

4. Why are there so many msedgewebview2.exe processes?

WebView2 uses a multi-process Chromium architecture containing browser, renderer, GPU and utility processes. Multiple processes can be completely normal.

5. Why does msedgewebview2.exe use so much RAM?

Memory consumption depends heavily on the application using WebView2, the complexity of its web content, the number of WebView2 controls, JavaScript workload and other resources.

6. Is 1 GB of WebView2 RAM usage normal?

There is no universal threshold. One gigabyte could be excessive for a simple application but understandable across multiple complex WebView2 instances. Available system memory and memory growth over time are more useful indicators.

7. Does high WebView2 memory mean there is a memory leak?

Not necessarily. A leak becomes more likely if memory continuously grows despite a stable or idle workload and does not recover appropriately when the host application closes.

8. Can I end msedgewebview2.exe?

Yes, as a temporary troubleshooting action, but applications using it may malfunction, display blank content or restart WebView2 automatically.

9. Why does msedgewebview2.exe restart after I kill it?

An application that requires WebView2 may automatically launch it again.

10. Can I permanently disable Microsoft Edge WebView2?

Generally, this is not recommended because Microsoft and third-party applications may depend on it.

11. Can I uninstall Microsoft Edge WebView2 Runtime?

It should not be used as a routine performance optimization. Applications requiring WebView2 may stop functioning or reinstall the Runtime.

12. Does WebView2 run even if I don't use Microsoft Edge?

Yes. Applications can use WebView2 independently of whether you personally use the Microsoft Edge browser.

13. How can I find which program is using msedgewebview2.exe?

Use Task Manager process relationships or PowerShell/CIM to examine ParentProcessId, executable information and command-line data.

14. Does WebView2 cause high CPU usage too?

It can. Complex JavaScript, graphics, video, background processing or host-application problems can cause high CPU usage.

15. Can WebView2 contribute to 100% memory usage?

Yes, particularly when many instances, applications or users are active. However, analyze all processes and Windows commit usage before concluding that WebView2 is solely responsible.

16. Is WebView2 a problem on RDS servers?

It can have a larger aggregate impact because many users may independently run WebView2-based applications.

17. Should I kill all WebView2 processes on an RDS server?

No. Identify the affected user and host application first. A global termination can disrupt several active users.

18. Will adding more RAM fix WebView2 high memory?

Additional RAM can reduce overall memory pressure, especially on busy RDS servers, but it does not fix an application memory leak or inefficient WebView2 implementation.

19. Can antivirus or EDR interfere with WebView2?

Security or application-control software can sometimes interfere with WebView2 processes. Investigate the interaction rather than permanently disabling security protection.

20. Should I delete WebView2 cache?

Not routinely. User-data folders can contain authentication data, cookies, permissions and application state.

21. How do I repair Microsoft Edge WebView2 Runtime?

Close affected applications and use Microsoft's official WebView2 Runtime distribution/update mechanism. Restart Windows if necessary and retest the application.

22. Does restarting Windows fix WebView2 high RAM?

A restart releases processes and memory and may provide temporary relief. If abnormal growth returns, investigate the host application.

23. Is WebView2 part of modern Windows application infrastructure?

Yes. WebView2 is widely used by Microsoft and third-party Windows applications to embed web-based interfaces and services.

24. Why does WebView2 memory increase throughout the day?

Possible reasons include increasing workload, additional WebView2 controls, cached content, long-running JavaScript, application lifecycle problems or a genuine resource leak.

25. What is the best permanent fix for msedgewebview2.exe high memory?

There is no universal one-click fix.

The most effective approach is:

Identify the host application → Measure WebView2 usage → Monitor growth → Update/repair the host application → Update WebView2 → Investigate persistent abnormal behavior.

Final Recommendation

Do not treat msedgewebview2.exe as an unnecessary Microsoft Edge background process.

The correct troubleshooting model is:

msedgewebview2.exe
↓
Identify the host application
↓
Measure total WebView2 memory
↓
Check actual Windows memory pressure
↓
Monitor memory growth
↓
Restart/update the host application
↓
Update/repair WebView2 if necessary
↓
Investigate persistent abnormal behavior

For an individual Windows 10/11 computer, restarting and updating the affected host application is often the quickest diagnostic step.

For Windows Server and RDS environments, administrators should additionally measure:

• WebView2 RAM per user;
• total session memory;
• concurrent user count;
• browser usage;
• available physical RAM;
• committed memory;
• host-application workload.

Most importantly:

Do not permanently disable, rename, delete or repeatedly kill msedgewebview2.exe simply because multiple copies appear in Task Manager.

Multiple WebView2 processes are a normal consequence of its architecture.

The real question is:

Which application is using WebView2, and is that application's resource usage normal or abnormal?

Technical Disclaimer

WebView2 behavior, Windows integration and applications using the Runtime can change over time.

Before making organization-wide configuration changes:

• confirm which application uses WebView2;
• review current Microsoft/vendor documentation;
• test changes on a non-production system;
• protect user data;
• maintain a rollback plan;
• avoid disabling security simply to solve an application problem.

This is particularly important on Windows Server, RDS, Citrix and other production multi-user environments.
