Windows signed you into a temporary profile
Why did my laptop create a temporary profile instead of my normal one?

Short answer
Windows loads a blank temporary profile when it cannot open your real one. That usually follows an unexpected shutdown during sign in, a full disk, antivirus locking the profile folder, or a duplicated entry in the profile list. Your files are still on the drive, untouched. The quickest thing to try first: restart two or three times first — A transient lock often clears on its own. Restart properly from the Start menu, not by holding the power button, and sign in again before changing anything. Most people are done in about 30 minutes.

Sounds like this
- •A notice about being signed in with a temporary profile
- •Empty desktop and default wallpaper
- •Your documents are missing but the machine works
Why it happens
Windows loads a blank temporary profile when it cannot open your real one. That usually follows an unexpected shutdown during sign in, a full disk, antivirus locking the profile folder, or a duplicated entry in the profile list. Your files are still on the drive, untouched.

Confirm your files are safe
Open C:\Users and look for your normal folder name with your documents inside. Seeing it there confirms this is a loading problem, not data loss. Copy anything critical to a USB drive now.

Free up disk space
Windows cannot build a profile with almost no free space. Settings, System, Storage, Temporary files, and clear at least a few gigabytes.

Fix the profile list in the registry
Run regedit, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. Right click ProfileList and export it as a backup. Find the S-1-5-21 key for your account: if there is a pair where one ends in .bak, delete the one without .bak and rename the .bak key by removing that suffix. Then set RefCount and State both to 0 in that key.

Check permissions on your profile folder
Right click your folder in C:\Users, Properties, Security, and confirm your account has Full control. Restore it through Advanced, Change owner, if it was lost.
- 6
Restart and sign in
Restart the machine after the registry change. Your desktop, wallpaper and files should return exactly as they were.
If none of that worked
Create a new local administrator account, copy everything from your old C:\Users folder into it, and move over. Do this rather than working long term in a temporary profile, because nothing you save there survives a restart.
