Windows 10: user10001 situation

I tried to free up some space for some games on steam then deleted my whole windows files by accident, which restarted my computer and it wouldn't let me log back into my account, i then watched a yt video and rebooted my laptop, Local option to keep my files and once it was done i opened the lock screen and it says "user10001" which i don't know the password to. I tried some methods like the command prompt regedit, and the cmd and utilman method, but it shows that the "user10001" is not actually a user, and now im stuck with no account to log into. Pls help

:)

@smoka Great you fixed it and would be interesting to know how you did it. Care to list the basic steps you took to do it so that it can help others stuck in the same situation?

 

PC wont boot up (No POST, No Video)

Aren't we being a little harsh? I know I can't be the only other person on this forum to have skipped checking the official memory compatibility list when building a computer. Had I been in the same situation and followed the same steps I would have thought I got a bum board too, regardless of whether or not the memory was on that list.

Solvusoft posts the same look-a-like steps for every problem you can think of, not very useful. The steps contain some variation depending on the problem, but I haven't found a situation where those step helped anything.
