First contact....
Boss came into work with his laptop (windows 10 home on it)
Windows updated last night. He said it was endlessly restarting and blank screens etc.
Turns out the update had corrupted his local profile and MS was trying to start with a temp profile to help... however, that was going very funky, BSOD's, graphical flickering etc.
I tired the usual reg tricks to re-point the profile to the correct directory on the HDD. however that caused issues and it didnt login. I then tried copying over the NTUSER.dat file from the default profile into the corrupt profile folder.
Restarted with multiple BSOD's and flickering screen, couldnt do anything.
Only logs in with safemode. (not sure why startmenu or settings screens dont work in safemode?) couldnt add new user through control panel as it all has been moved.
So used CMD to add a new user, didnt work for some odd reason, restart and the new user wasnt created...
Ended up using Linux live boot, then force mounting HDD to remove the old ntuser.dat file and windows managed to do a "temp profile" on startup. Created new user from settings. it worked. booted into new user. Copied old files across from old profile, then deleted old profile.
Then the usual endless setting tweaks for software thats got to be configured...
Thanks MS loving the new feature....
