Hi,

It is possible to fix, however it is slightly tricky. If you have trouble completing any of the following steps feel free to ask for more info.

First, are you able to log in to another administrator account on the affected computer? OR are you able to log in to the affected account and create a new administrator account?

If not then ignore the rest of this post.

If so then follow these steps; at each step make sure you read and understand the entire step:

Go to Control Panel and search for Create a Restore point, open the link and click on the Create button down the bottom right of the window

Follow the instructions to create a restore point.

NOTE: This fix WILL delete EVERYTHING on your Desktop and in your Documents folders. Make sure you back the contents up:


Go to the Hard Drive on your computer that has the most free space and create a new folder called Backup.

Then go to C:\Users\yourname and copy everything into the Backup folder you just created. Check that you can access your documents from the backup folder successfully.


All backed up? Good, now you have to delete your old profile and create a new one:


1. Delete the profile by using the Computer Properties dialog box. To do this, follow these steps:
a. Click Start, right-click Computer, and then click Properties (on the right hand side of the window).
b. Click Change settings.
c. In the System Properties dialog box, click the Advanced tab.
d. Under User Profiles, click Settings.
e. In the User Profiles dialog box, select the profile that you want to delete, click Delete, and then click OK.​
2. Click Start, type regedit in the Start search box, and then press ENTER.

3. Locate and then expand the following registry subkey (using the folder icons in the left toolpane): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

4. Right-click the SID that you want to remove (the one you want to remove is the longest one, eg:S-1-5-21-7623811015-3361044348-030300820-1013) and then click Delete. DO NOT DELETE ANY OF THE SHORTER SID'S. If there are 2 long SID's then left-click on them and the value for ProfileImagePath in the right side of the window should tell you which SID has the user with the broken profile associated.

5. Log on to the computer and create a new profile.

THEN copy everything back from the Backup folder to C:\Users\New Profile Name

Regards,
Reventon
