Question details
The user needs to recover missing files and programs after a computer restart caused OneDrive to sign out and the PC to seemingly revert to an earlier state.

- Product
- Windows and OneDrive
- Device & OS
- Windows
- Scenario
- After restarting the computer, the user experienced a system state reversion causing a changed wallpaper, logged-out OneDrive, and missing recent files and games.
- Observed behavior
- OneDrive signed out, recent documents and Steam games are missing from their usual locations, the desktop wallpaper reverted to default, and the system appears rolled back.
Verify that you are not logged into a temporary Windows user profile by checking your C:\Users directory, and ensure you know the exact Microsoft account credentials linked to your OneDrive.
Search OneDrive Online and Check the Recycle Bin
Locate files that might have been safely synced to the cloud before the system experienced the unexpected reversion.
OneDrive does not automatically delete files even if your storage limit is exceeded. The missing files may still exist in the cloud or within hidden sections of your OneDrive account.
Navigate to onedrive.com in your web browser and sign in using your Microsoft account credentials.
Use the search bar at the top of the OneDrive interface to search for specific missing file names or extensions.
Click on 'Recycle bin' in the left-hand navigation pane, select any mistakenly deleted items, and click 'Restore'.
Unlock your Personal Vault in your OneDrive root directory, as files stored here are frequently excluded from standard search results.

Recover via Windows File History or System Restore

Frequently Asked Questions
Why did my computer revert to an earlier state after a restart?
This usually happens if Windows encountered a critical error during an update, failing to load your normal profile and instead loading a temporary user profile. It can also occur if an automatic System Restore was triggered to prevent a total boot failure.
Does OneDrive delete files if my storage is completely full?
No, OneDrive does not automatically delete your files when you exceed your storage limit. Your account will simply stop syncing new files and edits until you free up space or purchase additional storage.
Where did my Steam games go after the Windows revert?
If Windows rolled back to a previous state, registry entries and desktop shortcuts for recently installed games might be missing. The actual game files are usually still present on your hard drive in the default Steam directory (C:\Program Files (x86)\Steam\steamapps\common). You can re-add them by verifying game files in the Steam client.
How can I tell if I am logged into a temporary Windows user profile?
If your desktop wallpaper changed to the default Windows image, your desktop shortcuts vanished, and your personal folders appear empty, you are likely in a temporary profile. You can usually fix this by restarting your PC one or more times, or by checking the C:\Users folder to locate your original user directory.
