There is a default 10 day go back period before Windows.old is automatically deleted.

This command can be used to see if there is time remaining before the automatic deletion:

Open administrative command prompt and copy and paste:

DISM /Online /Get-OSUninstallWindow

Post a share link.

Error 1168 = Absent Windows.old

If Windows.old was automatically deleted then to return from Windows 11 to Windows 10 possible options are:

a) manually backup files to another disk drive or the cloud > clean install Windows 10 > reinstall drivers and applications > restore important files from the disk drive or the cloud

b) have Windows 11 backup files to Windows.old > save Windows.old to another disk drive or the cloud > clean install Windows 10 > reinstall drivers and applications > restore important files from Windows.old

Can I create windows 10 ISO file in thumb drive fm this laptop running windows 11, n reboot this laptop using this thumb drive to reinstall windows 10? If affirmative, please share the procedure.

Thanks
