1)C:\Windows\System32>mountvol y: /s C:\Windows\System32>cd .. C:\Windows>y: Y:>cd efi\microsoft\boot\fonts Y:\EFI\Microsoft\Boot\Fonts>del .

2)Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader__.__" rmdir %systemroot%\SoftwareDistribution /S /Q rmdir %systemroot%\system32\catroot2 /S /Q

3. following this Microsoft article https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf

Answer 3

Hello,

What is the exact error message you have got?

1. Try to uninstall the third party antivirus software temporarily if there is any one installed.
2. Since you have tried to resize the reserved partition, try to resize a more larger size than 250MB such as 500MB.
3. For advacned troubleshoot, we could check the C:\Windows\Logs\CBS\CBS.log for more information.
