Hello guys, I just looked through my registry to delete old entrys and then I came across some weird folders with game names in it I surely never had installed on my pc (besides the one i wanted to delete): https://i2.woh.to/2017/01/30/018150d.jpg https://i1.woh.to/2017/01/30/02dab9c.jpg https://i3.woh.to/2017/01/30/0353355.jpg https://i3.woh.to/2017/01/30/04a15a2.jpg is this sth that is deleteable or will the system feel it? besides I have no idea what that folders are.
