Corrupt Local Windows 7 User Profile when computer attached to server domain

Step 1. To fix the user account profile, click Start and type regedit into the search box and press Enter.

Step 2. Registry Editor will open and you need to navigate to the following key:

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

Step 3. Click each S-1-5 folder and double-click the ProfileImagePath entry to find out which user account profile it relates to. (If the folder name ends with .bak or .ba follow Microsoft's instructions to rename them.)

Step 4. Once you have located the folder for the corrupt user profile (and it doesn’t have a .bak ending), double-click RefCount and change the Value data to 0 and click Ok.

Step 5. Next double click on "State" and make sure the Value data is also 0 and click Ok.

Step 6. Close regedit & restart your computer. You should now be able to log into your account.
