Frequently Asked Questions

Why did a Microsoft 365 update hide my non-Office desktop files?

While rare, severe update conflicts can occasionally cause Windows to fail to load your primary user profile. When this happens, Windows logs you into a temporary blank profile, which makes it appear as though your desktop icons and files have been deleted or hidden.

Will repairing Microsoft 365 delete my personal documents?

No, using the built-in 'Modify' and 'Repair' tool in Windows Settings only scans and fixes the core application files and registry keys for the software. Your personal documents, spreadsheets, and data remain entirely untouched.

What should I do if Safe Mode doesn't bring my files back?

If files are still missing in Safe Mode, navigate to the C:\Users folder using File Explorer and check if your original user folder still contains your documents. If the files are there but inaccessible, you may have a corrupted profile and should contact Microsoft Support for recovery assistance.
