Answer 1

Try these steps in order for a Windows 11 Insider Preview update that keeps failing after restart.

Run the Windows Update troubleshooter.
- Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
- Find Windows Update and select Run.
- Complete the prompts, then try the update again.
Disconnect nonessential hardware.
- Unplug USB drives, external hard drives, printers, scanners, speakers, headphones, and undock the laptop if it is in a docking station.
- Retry the update.
Make sure Windows Update has all available updates.
- Go to Settings > Windows Update and check again.
- For Insider devices, also confirm the device is enrolled correctly under Settings > Windows Update > Windows Insider Program and manually select Check for updates.
Remove third-party antivirus or security software temporarily.
- Non-Microsoft antivirus can block upgrades.
- Go to Control Panel\Programs\Programs and Features, select the antivirus app, then Uninstall.
- Important: make sure the reinstall media and activation details are available before removing it.
Repair system files.
- Open Command Prompt as administrator.
- Run:
```
     DISM.exe /Online /Cleanup-image /Restorehealth
```
- Wait for the success message.
- Then run:
```
     sfc /scannow
```
- Wait until the scan reaches 100%, restart the PC, and try Windows Update again.
Reset the Windows Update cache.
- Warning: these are advanced command-line steps and require administrator permissions.
- Open Command Prompt as administrator and run these commands one at a time:
```
     net stop bits
     net stop wuauserv
     ren %systemroot%\softwaredistribution softwaredistribution.bak
     ren %systemroot%\system32\catroot2 catroot2.bak
     net start bits
     net start wuauserv
```
- Restart the device and try the update again.
Check for software conflicts.
- Perform a clean restart into Windows to start with a minimal set of drivers and startup programs, then retry the update.
If the Insider update still fails, use Windows recovery reinstall.
- Go to Settings > System > Recovery.
- Select Reinstall now.
- This was the accepted resolution in similar Windows 11 update failure cases.
If the device is not receiving Insider updates at all, verify these Insider-specific items:
- Confirm the device is already on Windows 11.
- Confirm Windows is activated in Settings > System > Activation.
- Confirm the correct Insider channel is selected in Settings > Windows Update > Windows Insider Program.
- Check whether the current build is already the latest for that channel.

If the failure continues, check Settings > Windows Update > Update history and note the exact error code. That determines whether the issue is a driver problem, disk space problem, or compatibility problem.

Hi, @husna Sakilan

I’d like to narrow down exactly where the update is failing first.

Does the update fail before the restart, or does the PC restart and begin installing the update?
If you see an installation percentage during restart, at what percentage does it fail or roll back?
After Windows starts again, what exact error code is shown under Settings > Windows Update > Update history?
Which Windows Insider channel are you using: Canary, Dev, Beta, or Release Preview?

Also, press Windows + R, type winver and let me know the version and OS build shown.

Since you mentioned work compliance, is this your personal PC or a device managed by your company or organization?

Click "Add comment" to let me know.

Thanks!

Thank you for letting me know.

Your current Build 26220.9223 is a Windows 11 25H2 Beta Insider build.

Please go to Settings > Windows Update > Update history and look under "Failed updates".

What is the exact name of the update that failed, and what error code is shown? For example, it may show something like 0xC1900101 or another 0x error.

Also, during the restart, do you see any message such as "Undoing changes made to your computer", or does it simply restart back into Windows?

One other point: since you use this personal laptop for work compliance, does your employer specifically require Windows 11 25H2, or do they require a particular OS build? Insider Preview builds can sometimes be treated differently by company compliance systems.

Thanks!

for work compliance my company requires us to update the windows everytime we come to login our account for work, so technically we're required to keep it updated everyday

Thanks, that helps narrow it down.

Since the update reaches about 30% and then shows "Undoing changes made to your computer", Windows is downloading the update successfully but failing while applying it during the restart.

The 0x80070057 and 0x800704c7 errors do not point to one specific cause, so please repair Windows and the Windows Update components first if you haven’t already.

First, go to Settings > System > Troubleshoot > Other troubleshooters and run "Windows Update".

Then open Command Prompt as administrator and run these commands one at a time:

DISM /Online /Cleanup-Image /RestoreHealth

Wait for it to complete, then run:

sfc /scannow

Restart the laptop when both have finished and try Windows Update again.

If it still reaches 30% and rolls back, please let me know whether DISM and SFC completed successfully or reported any errors. I can then guide you through resetting the Windows Update components.

Also, since this is a work-compliance laptop, does your company allow Windows Insider Preview builds, or do they only require Windows itself to be fully updated? Your PC is currently on the Beta Insider channel, which receives preview builds that can occasionally fail or have known issues.

Thanks!
