Do not give random people on the internet access to your computer. You are asking for trouble. They could wipe your computer, install ransomware, or steal all of your data and so much more.

Take your pc to a repair shop if you are not tech savvy. Do not just assume you can delete random system files and your pc will continue to work. I know i have told you this before.

tried taking it to a shop, they immedialy attemeted to do the exact stuff i DONT want.

Openly soliciting the wide internet is only going to attract someone who will do you harm.

For the future: I'm using Geek Uninstaller[geekuninstaller.com] for removing most of the applications on my system. It will look for leftover folders and registry entries and remove them too.

If your system is full of junk you want to get rid of, try to setup a new one and do a new clean Windows installation.

You can check for "Windows debloat" scripts like this one: https://github.com/Raphire/Win11Debloat

They will remove unnecessary stuff and do some settings for you. But be careful ^^

It is better to learn it to do it yourself. Ask about videos or guides how to do it, if googling skills aren't there yet. It is not hard and you will learn useful things. That way you don't risk yourself getting in trouble by bad people.
