Windows 10: Windows 10 - User Profile corrupted / how to fix

My user name disappeared from the login screen.


I can access the CMD menu by clicking Shift-Restart from start up screen as "Administrator X:\windows\system32\cmd.exe" opens up.


From there I'm stuck. Various web searches techniques to create a new user name / password, but so far none have been successful.


My goal is to create a new user name and password that will allow me to access all the files on the system.


Help appreciated!

Corrupted User Profile

Hi,

There maybe a couple of reasons behind this misbehavior such as a corrupted system file. However, we would like to be able to verify which process exactly is corrupted.

• When you install, does it give you any form of error message when it fails?
• What other processes doesn't go through on the said User account?

As per troubleshooting, you may refer to
Likhitha V's response on this thread. See if it applies to you. However,
just to give you a heads up. The steps are about creating a new user profile and deleting the current one. I suggest you back up your files so you may be able to transfer it. You can also find information about it on the same thread.

We'll be waiting for your response. If you have any other concerns, don't hesitate to come back to us.

 

Fix a corrupted user profile in Windows 10

Source: Windows 10 sporadic user profile corruption (default/ntuser.dat locked by SYSTEM)

After Enterprise deployment of Windows 10; organisations are faced with sporadic user profile corruption.

Scenario:

• The corruption seem to happen for the 2nd user and other users from then on.
• The corruption seem to follow a 'Sleep' phase (after the machine wakes up)
• The corruption seem to happen if the 'Sleep' extends over night.
• The corruption only seem to happen if the 'currently logged on' user is not logged out but the new user logs-in by 'switching accounts'.
• Event logs specify the C:\default\ntuser.dat file being locked by the SYSTEM user.

Solution:

My supposition is that this might be a BUG in the new user profile creation process in Windows 10. But the below implementation fixes the above issue gracefully and permanently.

In short, C:\default\ntuser.dat is locked by the SYSTEM; only the SYSTEM can give it back to you. So request the SYSTEM to release control politely. Ask the SYSTEM to release control on event ‘On Local disconnect from any user session’.

Create a schedule task using AD group policy with the below configuration.









Any question please message me.
