Sometimes Windows may not read your correct user profile properly, instead, will load with temporary profile which will look like a new user profile. If you are not aware that it is a temporary profile on your Windows computer, then you will be surprised to see the brand new desktop without your files, folders, program shortcut icons and any personalized settings.

Cause of corruption can be a recently installed update or a software or incorrectly shutting your computer down for that matter. If you have already tried restarting your computer 3 to 4 times (Yes, that has worked for some users) then start following the solutions below. Please, use and administrator account.

Step 3. Under ProfileList in the left pane, locate the SID keys which are something like “S-1-5-21..some long number”. You will see two or more of these SID keys, probably one will have .bak at the end and other one will be without it. The one with .bak is the link to your inaccessible profile and there will be one other that is to the temporary profile you are currently using.

Step 4. To confirm, click on any SID key to highlight it. Now in the right pane, next to ProfileImagePath in the Data row, it will be “C:\Users\’Your Inaccessible Profile Name’”. Click on all SID keys like “S-1-5-21….some long number” and delete the keys that have your profile name next to ProfileImagePath EXCEPT the one with .bak at in the end. Confirm the message and click OK.

Step 5. Right click on the “S-1-5-21….some long number” key with .bak at the end, and click Rename.
Delete “.bak” from the end of the key. Close the window. Restart your computer.
Now try logging in your original profile. If you’re still facing the same issue, then we can delete the remaining key too so that a new registry key is created.

SOLUTION 3. System File Check
Step 1. Press Windows key + R and type “cmd”.
