Solution for User Profile Unable to load Files or Currupted

Appears while attempting to logon in Windows Vista, 2008, 2008 R2 and 7.

Exact cause is unknown, but this issue may occur if the user profile was manually deleted by using the command prompt or Windows Explorer by a user or by some program. A profile that is manually deleted does not remove the security identifier (SID) from the user profile list in the registry. Since the SID is still present, Windows will still try to load the profile by using the ProfileImagePath that points to a nonexistent path. Therefore, the profile cannot be loaded.

This can also be a issue with the user profile entering into a backup state, or if the C:\Users\(User Name) user profile folder is manually renamed.


Steps 1: Restart the computer in SMWN or in SMWC (If you have only one profile was there in the computer)
Steps 2: Open the command prompt window in Administrator.
Steps 3: Enable the hidden admin profile.(net user administrator /active:yes) and restart the computer. Disable the admin profile(net user administrator /active:no) and press  enter.
Steps4:  once restarted the computer log-in with the admin account.
Steps5: Trawl through the Registry
Open the Start menu. In the Start Search area, type regedit and press Enter (if prompted by UAC, click Continue/Yes). In regedit, go to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Expand the ProfileList key and look for the SID key (named "S-1-5"...) with a long number that ends in ".bak". Click it, and look at the ProfileImagePath value in the right pane to verify that this is the user account profile that has the error.

a) If you have two SID keys with the same number (with one ending in ".bak" and one showing the affected user account in the ProfileImagePath value), continue to Step 3;
b) If you have just one SID key with the ProfileImagePath value showing the affected user account, proceed to Steps 7

Steps 6 : Two SID keys with the same number
a) Of the two SID keys that corresponds to the affected user account, right-click the SID key that does NOT end in ".bak" and click Rename.
b) Add .bk to the end of the numbers and press Enter.
c) Right-click the other SID key that DOES end in ".bak" and click Rename.
d) Remove only .bak from the end of the numbers (so that it has the same name as the other SID key did before you renamed it) and press Enter.
e) Now go back and Rename the first one with .bk to .bak now at the end of the numbers and press Enter.

Proceed to Step 8...

Steps 7: Only one SID key ending in ".bak"
a) Right-click the SID key that corresponds to the affected user account and click Rename.
b) Remove only .bak from the end of the numbers, and press Enter.
c) In the right pane, right-click the RefCount value (if none exists, right-click the right pane and click New and DWORD (32 bit) Value, then type RefCount and press Enter), and click Modify.
d) Type 0 into the Value Data textbox and click OK.
e) In the right pane, right-click the State value and click Modify.
f) Type 0 into the Value Data textbox and click OK.

Steps8: Try logging on again!
Close regedit and restart the computer. You should be able to logon now...
