Hi, I just upgraded to windows 10 today, and when I try to log in the first message it gives me is a ridiculous long error code, and wont let me do anything.
"c:windows\system32\config\systemprofile\desktop is not available....." or something rather.
Can't open the start menu, or even explorer when i hit windows key + e.

When I try to do anything at all (even open network settings) i get the error message
"The server process could not be started because the configured identity is incorrect. Check the Username and Password."

Please help! I need my laptop for work to do before end of the weekend!
