Windows 10: Login ERROR: User login failed. Profile cannot be loaded/started.

Hi Guys,
I've recently got an issue with loading profile settings after probably deleting one of the Admin profiles on Windows 10 Home.

I can't load:
1. The most important: Built-in Adminstrator profile: Error: " Location/Path C:/Windows/sytem32/config/systemprofile/Desktop" is unavailable. I got only empty black screen, bottom-left-hand corner windows icon doesn't show up the menu - is irresponsive. I can't do anything - eveng craetimng new folders. Only Some software work , namely BitDefender Total Security, NVidia, Intel etc

2. Fortunetely, I'ev got another Admin account which works fine. I can create new users/profiles but I get this error anytime I enter the user's profile:" a User log in failed. User's profile files cannot be loaded.

I've found the path in regestry:
It confirms that only one with thwe right path to my profile works fine. Others don't have a correct path.

See the print screen below:





I hope I won't have to format disc and totally reinstall Windows. Thank you for you help.

:)

 

Windows 10 Pro login

I am having problem with my Windows 10 Pro laptop. Whenever I login with my ID it says "The User Profile Service service failed the sign-in. User profile cannot be loaded."

And when start the computer in safe mode it shows error message "Unkown hard error". And windows start button or search is also not working in Safe mode. Please help.

 

win 10 corupt default user profile

We have three logins and using recommended “Safe Mode” login then going to “regedit”

the logins had the following difference.



Faulty Login
Other 2 working logins

Name
Type
Data


RefCount
REG_DWORD
0x00000002 (2)
0x00000000 (0)

State
REG_DWORD
0x00000100 (256)
0x00000000 (0)

Note there were no folders .bak





Using the faulty Login.

1. If you click the start menu a messaged is displayed “Critical Error Your Start Menu isn’t working. We’ll try to fix it next time you sign in.

2. Cortana will not activate.

3. Action Centre will not activate.



If I create a new login and then try to use it we get this message “ The User Profile Service service failed the sign-in. User profile cannot be loaded.



My investigation point to “The Default User Profile is corrupt”



thanks

 

3 first entries seem to be broken or proper entries of the profiles I have (2 more - one local and one connected to a Microsoft acount)
The kast one .....-21-.... is fine and working (admin account)
