Ouch..,. ok so first question is, what file exactly was it?

You say you don't have access to 'some files and apps' - that suggests you can still boot up the machine and use it a bit?

What operating system are you using?

I dont really remember the name of the folder (but i tried some other solutions before that but every time i was deleting it, after a reboot i would come back. Yeah I can still boot up my PC it doesnt have a problem. And im operating on Windows 10

I was trying to remove some permissions from a user i havent seen before, who was removing some of MY permissions and then boom no access to some of my apps

A real user, or a system account?

In any case, this is the time to recover from the full drive backup you made before this happened.
Or a System Restore point.

Okay so I've done something but can someone tell me who is this random ass user? I've been trying to open a program and it says access denied
P.S. I doesnt even let me open lightshot but the account name is "Account Unknown(S-1-5-21-3871319346-1381223376-3227377524-1001)" and has all of the permissions

There's not much else to suggest, other than a complete reinstall.
No telling what these "permissions" did.

Should I just format both of my drives?

Should I just format both of my drives?

Depends what is on them.
I would start with just the OS drive, with a full reinstall.

See if you can reset your pc back to before when all was well.
Use system restore, and pick a previous time when all was well.
Windows should have put in an entry before an update.
For the future, take a user checkpoint before doing anything that you are not certain about.

If you did not have system restore configured, you are out of luck.
