Some of the windows files got deleted too, as the system doesn't function properly. The current state of the computer is that the whole C:\users\ location got deleted and what's worse, it didn't end up in the trash can either. I stopped it as soon as I realized what is going down, but it was too late.
However, it didn't delete the old one with corrupted files, so I run some more commands (like rd /s /q C:\$ but suddenly something went wrong and I only watched things from C: drive getting deleted one by one in the explorer opened in the background. In addition I changed the name of the recycle bin with corrupted files, run some more commands and it seemed to fix the problem, as the Windows created new recycle bin.
Long story short, I was playing with some commands in a cmd console to delete some corrupted files in the recycle bin.
