How to Fix Windows 11 Reverting Files and Excel Changes After Restart
Question details
The user's Windows 11 computer automatically deletes newly downloaded files, uninstalls recent software, and discards all Microsoft Excel changes upon restarting, reverting the system completely to a specific past date.
- Product
- Windows 11 / Microsoft Office
- Device & OS
- Windows 11 (HP Envy x360 laptop)
- Scenario
- Rebooting the laptop after completing work on Excel files, saving images, or installing new diagnostic software.
- Observed behavior
- All system and file modifications made after May 5, 2023, vanish entirely after a restart, causing the laptop to act as if it was restored from an old system image.
Immediately back up any important new files, downloads, or recent Excel documents to an external USB flash drive or a cloud storage service to prevent permanent data loss before you restart your computer again.
Disable Disk-Freezing or System Recovery Software
Third-party virtualization or disk-freezing tools reset your drive to a baseline state on every boot.
Software such as Deep Freeze, Reboot Restore Rx, Windows Unified Write Filter (UWF), or specific HP recovery tools are designed to protect public or shared computers by erasing all session changes upon restart. If enabled accidentally on a personal device, it will wipe your recent downloads and Excel edits.
Click the Windows Start button, type 'Control Panel', and press Enter. Navigate to 'Programs' > 'Programs and Features'.
Scan the installed applications list for names like Deep Freeze, Reboot Restore Rx, Unified Write Filter, or HP Recovery Manager.
Right-click the identified disk-freezing program and select 'Uninstall'. Follow the on-screen prompts and restart your computer to permanently apply the removal.
Fix a Temporary User Profile Issue
Logging into Windows with a temporary profile causes all local file changes to be discarded when you sign out or reboot.
Run System File Checker and Check Disk
Severe hard drive corruption or file system errors can cause Windows to fall back to the last known good configuration automatically.
Safeguard Your Documents with WPS Office Cloud Sync
While resolving complex Windows 11 system restore issues, you can prevent local data loss by switching to WPS Office. It provides automatic cloud synchronization, ensuring your spreadsheets and documents are securely backed up online regardless of what happens to your local hard drive during a restart.
- 1. Download the Installer: Visit the official WPS Office website and download the free installer for Windows.
- 2. Activate Cloud Backup: Log in with a free WPS account to enable automatic cloud sync for your documents.
- 3. Edit Your Spreadsheets: Open your existing Excel files directly in WPS Office and edit them securely with automatic online saving.
Frequently Asked Questions
Why does my computer delete my recent files after every restart?
This happens when your computer uses disk-freezing software (like Deep Freeze or Unified Write Filter), boot restoration tools, or logs you into a temporary user profile. These tools intentionally prevent permanent changes to the hard drive, reverting everything to a baseline state upon reboot.
Could Windows Storage Sense be causing my software and Excel files to disappear?
No. While Storage Sense can automatically delete old files in the Downloads folder or recycle bin to free up space, it will not uninstall diagnostic software or delete recent modifications made to Excel documents. A full system rollback indicates a deeper drive or OS-level issue.
How can I permanently save files if my local drive keeps reverting?
Until you fix the underlying Windows rollback issue, you must manually save your Excel documents and important files to an external USB thumb drive, or use a cloud storage service like WPS Cloud, OneDrive, or Google Drive, which sync files online before the system shuts down.
