Hi @ukracer,
If your HP ZBook Studio 15.6 inch G8 Mobile Workstation PC has difficulty updating Windows 11 despite having available space in the EFI partition, follow these steps to troubleshoot and resolve the issue:
-
Check Update Requirements: Ensure your device meets all the requirements for the Windows 11 update. This includes compatibility with TPM 2.0 and Secure Boot.
-
Free Up More Space:
- Although you have 100 MB available, sometimes Windows updates require more space temporarily. Try freeing more space in the EFI partition if possible.
-
Run Windows Update Troubleshooter:
- Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
- Select Windows Update and run the troubleshooter.
-
Check for Storage Issues:
- Use the Disk Cleanup tool to clean up unnecessary files on your system drive.
- Clear temporary files and any old Windows installation files that might be using up space.
-
Reset Windows Update Components:
-
Open Command Prompt as administrator and run the following commands to stop Windows Update Services:
net stop wuauserv net stop cryptSvc net stop bits net stop msiserver
-
Rename the SoftwareDistribution and Catroot2 folders to reset Windows Update components:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 Catroot2.old
-
Restart the services:
net start wuauserv net start cryptSvc net start bits net start msiserver
-
-
Manually Download Updates:
- Sometimes downloading the update manually from the Microsoft Update Catalog and installing it can resolve the issue.
