Windows 10: I accidentally deleted this file called S-1-5-21-2925736768-2535686238-1746969815-1001.bak

I accidentally deleted this file when I tried to fix my pc, because it always says that it can't sign in to my account. It always puts me in a temporary account. Now, whenever I try to sign in on my account which is still directing me into a temporary account, the screen goes black for like 5-10 minutes until I can use my pc. What should I do?

:)

Fix You've been signed in with a temporary profile in Windows 10  


That's ok. I'm happy to help. Please feel free to ask any questions you may have.

If your "C:\Users\TJA" folder is still there with your files, then you would want to use step 12 in the tutorial to try and restore this profile folder for your account.

If not, then you could delete both S-1-5-21-....-1001 and S-1-5-21-....-1001.bak SID keys for your account to have a new profile folder created for your account the next time you sign in to it.
