Hey Mariyam — great question.
Unfortunately,
a System Restore point cannot revert a full Windows 11 upgrade back to Windows 10. Here's why:
What a Restore Point Does:
A
restore point only reverts
system files, drivers, and registry settings —
not the OS version. So if someone upgrades to Windows 11, even if they had restore points from Windows 10, those:
- won’t show up anymore
- and can’t undo a full OS upgrade
What Can Roll Back a Windows 11 Upgrade?
Option 1: Windows 11’s built-in rollback (within 10 days)
Option 2: Manual Reinstall
If it's been
more than 10 days, or if they deleted the Windows.old folder:
- They’ll need to manually reinstall Windows 10 using bootable media (USB).
- They can choose to:
- Keep personal files (if doing an in-place downgrade)
- Or do a clean install (wipes everything)
Suggestion:
Before downgrading,
back up everything, including:
- Files on Desktop/Documents
- Browser profiles
- Licenses, passwords (especially if in a browser vault)
- VM config if they use any
If you want, I can walk you through checking whether the Windows.old folder still exists or help prep a USB installer for Windows 10.
