Undo first, then uninstall
This is the order that matters, and it is not the obvious one.
Uninstalling w0a removes the application. It does not revert the Windows settings it changed — those are Windows settings, not w0a's files, and an uninstaller that silently rewrote your machine on the way out would be doing something no uninstaller should do.
So if you want the machine back the way it was:
- Open w0a
- Go to Backups & Restore
- Restore the checkpoints you want reverted
- Then uninstall
If you have already uninstalled and want to undo the changes, install it again, restore, and then uninstall. The undo log lives at %ProgramData%\w0a\backup.json and survives uninstallation for exactly this reason.
Uninstalling
Settings → Apps → Installed apps → w0a → Uninstall, or the Uninstall page inside w0a itself.
What is left behind
%AppData%\w0a\— your settings, the local error log, the machine fingerprint file. Delete the folder if you want it gone.%ProgramData%\w0a\backup.json— the undo log. Deleting it means the changes can no longer be reverted from a backup; the repair cards on the Fix page still work, because they write the Windows default rather than reading a backup.
Nothing is left running: no service is installed and no scheduled task is created.
Your licence
Uninstalling does not consume or release anything. Your key stays valid for its period, and reinstalling on the same machine activates again with the same key. Changing machines is covered in I changed my PC.
