Error-You've been signed in with a temporary profile' Error on Windows 10

 Sometimes, after a cumulative update user gets this error after login-You've been signed in with a temporary profile'.

And, the settings, documents are not available.

Solution: The solution involves registry edit, so be careful and take a backup.

While signed in to the account with the temporary profile, open a command prompt.

Enter the command below into the command prompt, and press Enter.

 whoami /user

Make note of the SID (Security Identifier) for this current account. You will need to know the SID (ex: S-1-5-21-....-1001) for your account

 

 If this account is a standard user, then you will need to sign out and sign in to an administrator account to be able to continue on with the steps below.

 

Open regedit.

Navigate to the ProfileList key at the location below in the left pane of Registry Editor.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

 Find the userid

If it is listed as SID.bak, rename it without .bak

If it is listed as without .bak, then updated the "Profile Imagepath" Value name with correct path.
