If your Windows computer displays the following message during startup:

"Windows created a temporary paging file on your computer because of a problem that occurred with your paging file configuration when you started your computer. The total paging file size for all disk drives may be somewhat larger than the size you specified."

Advertisement

it indicates that Windows was unable to use the configured paging (virtual memory) file during boot. To prevent system instability, Windows automatically creates a temporary page file so that the operating system can continue functioning.

Although your computer may continue to work normally, this warning should never be ignored because it often points to disk configuration issues, corrupted system settings, storage problems, or incorrect virtual memory configuration.

This guide explains what a paging file is, why this error occurs, how Windows handles virtual memory, and provides detailed troubleshooting and repair procedures.

What is a Paging File?

A Paging File (Pagefile.sys) is a hidden system file used by Windows as Virtual Memory.

When physical RAM becomes full, Windows temporarily moves inactive memory pages to the paging file.

Typical location:

C:\pagefile.sys

It helps Windows:

• Prevent application crashes
• Run large applications
• Support memory dumps after BSOD
• Improve multitasking
• Extend usable memory beyond installed RAM

What is Virtual Memory?

Virtual Memory is a combination of:

• Physical RAM
• Paging File (Disk Storage)

Example

Installed RAM

16 GB

Configured Page File

8 GB

Available Virtual Memory

24 GB

Why Windows Creates a Temporary Paging File

Windows creates a temporary page file whenever it cannot access the configured page file during startup.

Possible reasons include:

• Missing drive
• Changed drive letters
• Corrupted Pagefile.sys
• Damaged registry settings
• Insufficient disk space
• SSD/HDD problems
• File system corruption
• Permission issues
• Disk disconnected during boot

Common Causes

1. Page File Located on a Missing Drive

Many users move the paging file to:

• D:
• E:
• Secondary SSD
• External HDD

If that drive becomes unavailable, Windows cannot load the paging file.

Result:

Temporary Paging File Created

2. External Drive Removed

If Windows was configured to store the paging file on:

• USB HDD
• USB SSD
• Docking station

and it is disconnected,

Windows automatically creates a temporary page file.

3. Drive Letter Changed

Example

Previously

D:

Now

E:

Registry still points to D:.

4. Corrupted Pagefile.sys

Power failure

System crash

Improper shutdown

Bad sectors

can corrupt

pagefile.sys

5. Disk Errors

File system corruption

Bad sectors

NTFS corruption

may prevent Windows from reading the paging file.

6. Low Free Space

Windows cannot expand or recreate the paging file when the drive is almost full.

Recommended free space:

At least

10–20 GB

7. Registry Configuration Problems

Registry stores page file location.

Key:

HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Control
Session Manager
Memory Management

Value

PagingFiles

Incorrect entries trigger this error.

8. Corrupted Windows Files

Damaged system files may prevent Virtual Memory initialization.

9. SSD or HDD Hardware Failure

A failing storage device may intermittently fail during boot.

Symptoms include:

• Slow startup
• Disk timeout
• Event Viewer errors
• Temporary paging file warning

10. Improper Virtual Memory Configuration

Examples

No paging file selected

Manual size too small

Incorrect drive selected

Disabled paging file

Symptoms

Users may experience:

• Startup warning
• Slow boot
• Low memory errors
• Random application crashes
• BSOD
• System freezes
• Performance degradation
• Event Viewer errors
• High disk usage
• Failed memory dump creation

How to Check Current Paging File Settings

Open

Win + R

Type

sysdm.cpl

Navigate to

Advanced

Performance

Settings

Advanced

Virtual Memory

Change

Verify:

• Automatic management enabled
• Correct drive selected
• Recommended size

Check Current Paging File Using Command Prompt

wmic pagefileset list /format:list

or

wmic pagefile list /format:list

Check Registry Configuration

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v PagingFiles

Example

C:\pagefile.sys 0 0

Restore Automatic Page File

Open

System Properties

Enable

Automatically manage paging file size for all drives

Click

Set

Restart Windows.

Recreate Pagefile.sys

If corruption is suspected:

Disable paging file

Restart

Enable automatic management

Restart again

Windows creates a fresh

pagefile.sys

Check Available Disk Space

Run

wmic logicaldisk get caption,freespace,size

Ensure:

• C: has sufficient free space
• System drive is healthy

Check Disk Errors

Run

chkdsk C: /scan

For deeper repair:

chkdsk C: /f

or

chkdsk C: /r

Repair Windows Files

Run

DISM /Online /Cleanup-Image /RestoreHealth

Then

sfc /scannow

Check Disk SMART Health

Use tools like:

• CrystalDiskInfo
• Hard Disk Sentinel
• Samsung Magician
• WD Dashboard
• SeaTools

Check:

• Reallocated sectors
• Pending sectors
• CRC errors
• SSD health

Check Event Viewer

Open

eventvwr.msc

Review:

Windows Logs

System

Look for:

• Disk
• Ntfs
• StorAHCI
• volmgr
• Kernel-Boot

Check Storage Connections

Desktop

• SATA cable
• Power cable
• NVMe seating

Laptop

• SSD connector
• Loose storage module

External drives

• USB cable
• USB bridge
• Dock

Recommended Page File Size

General recommendation:

Microsoft generally recommends allowing Windows to manage the page file automatically unless there is a specific administrative requirement.

When Manual Configuration Makes Sense

Manual configuration may be useful for:

• Dedicated servers
• SQL Servers
• Virtual machines
• High-performance workstations
• Systems with specific memory dump requirements

Preventive Measures

• Keep Windows updated.
• Avoid storing the page file on removable drives.
• Maintain adequate free disk space.
• Monitor SSD/HDD health regularly.
• Perform graceful shutdowns.
• Replace failing storage devices promptly.
• Run chkdsk and sfc periodically if disk issues occur.
• Use reliable UPS protection to avoid sudden power loss.
• Leave virtual memory set to System Managed unless you have a specific reason to customize it.

Frequently Asked Questions (FAQ)

1. What does "Windows created a temporary paging file" mean?

It means Windows could not access the configured page file during startup and created a temporary one to maintain system stability.

2. Is this error dangerous?

Not immediately, but it may indicate underlying configuration or storage issues that should be investigated.

3. Can I disable the paging file completely?

It is generally not recommended. Some applications and Windows features rely on it, even on systems with large amounts of RAM.

4. Where is the page file stored?

Typically at:

C:\pagefile.sys

5. Can a failing SSD cause this error?

Yes. Storage hardware failures can prevent Windows from reading or creating the paging file.

6. Does low disk space trigger this problem?

Yes. If the system drive lacks sufficient free space, Windows may be unable to create or expand the page file.

7. Should I manually set the page file size?

For most users, System Managed is the best option. Manual sizing is usually reserved for specialized workloads.

8. Does reinstalling Windows fix the issue?

If the cause is software or configuration related, a clean installation may resolve it. If the drive is failing, the issue will likely return until the hardware is replaced.

9. Can registry errors cause this warning?

Yes. Incorrect PagingFiles registry entries can prevent Windows from locating the configured page file.

10. Which diagnostic tools help troubleshoot this issue?

Useful tools include:

• CHKDSK
• SFC
• DISM
• CrystalDiskInfo
• Hard Disk Sentinel
• Event Viewer
• Windows Memory Diagnostic
