Hello @sgrygowski and welcome to the Proxmox Community Forums.

I would like to point out three things right at the start:

  1. We only provide support in German or English. Therefore, please do not post screenshots in Polish in future.
  2. This is a forum for Proxmox virtualization, not for troubleshooting Windows issues.
  3. The more information you provide about your problem, the better we can help you. Based on your post, I can only gather that you are experiencing a Windows-specific issue with the updates, which, based on my current knowledge of your post, has nothing to do with Proxmox VE.

Thank you for your understanding.

Error code 0x8000ffff generally stands for “E_UNEXPECTED” or unexpected error. This error typically occurs during Windows updates when system files are damaged or certain services are not running correctly. Maybe this would help:

Code:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Maybe also delete tempfiles:

Code:
net stop wuauserv
net stop bits
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
net start wuauserv
net start bits
