Profile erased - Computer using TEMP profile

Registry fix:

1. While signed in to the account with the temporary profile, open a command prompt.
2. Enter “whoami /user” command to get SID (Security Identifier, a SID is a string value that is used to uniquely identify users.) SID eg.: S-1-5-21-2171760768-3957144033-4256508931-1001
3. Open ‘Registry Editor’ (type ‘regedit’ in Run)
4. Navigate to the ProfileList key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
5. In the left pane under the expanded ProfileList key, look to see if the SID key from step 2 above is listed with .bak (eg: S-1-5-21-…-1001.bak) and/or without .bak (eg: S-1-5-21-…-1001) at the end.
6. If the SID key is without .bak: In the right panel of the SID key (eg: S-1-5-21-…-1001), double click on the ProfileImagePath value name to modify it. Enter the correct path (eg: C:\Users<user-name>) of the user’s profile folder, and click OK. Verify that the State DWORD is set with a value data of 0 (number zero). 
7. If the SID key is with .bak: Right click on the SID key (eg: S-1-5-21-…-1001.bak), click on Rename, and rename the SID key to only remove “.bak” (eg: S-1-5-21-…-1001) at the end of the key’s name .
