I bought the pc pre used and the boot drive is almost completely used up. 469 gbs are being used but when i check storage and other programs to see what is using it up i cant find what it is. Is there anyway I could just delete everything but keep the os and just start new?

Also, when i check storage it says the largest app is 627 mbs
