So someone in my neighborhood asked me to clean their PC, what

Do you know if he has a previous Linux experience ?
Is it a good friend ?

Otherwise, install him something like Linux mint or OpenSUSE.

>>59465936
Get serial number if possible
Ask them what files/programs they would like to keep
Reinstall OS
Add everything back

download tron script, run it overnight

harvest nudes, porn history, personal details etc.. for blackmail

>>59466768
thissssssssssssss

then charge $50

Backup personal data and reinstall is the only thing worth doing

Easy start would be Glary Utilities or CCleaner.
Both have free options, just watch out for the packaged software.
Use the ESET online scanner for viruses.
This will take like 10 minutes of your time because I assume they're not paying.

This is a good idea if you have a couple of hours you want to kill. Windows 10 practically installs the drivers itself just programs like MS Office you have to watch you dont lose.

obviously install a key logger and then give it back to him

save important files then reinstall

>>59465936
Just turn off all of the useless startup processes normies get tricked into running

That's likely the cause of any slowdown they're experiencing

"Cleaning" a borked Windows install is an exercise in futility. Format, reinstall.
