Hi, I'm looking to reset my computer to factory mode but to keep Windows 10 which it came with. So basically when I got the computer it was ready to go with Windows 10, that's the point I'm looking to get back to due to performance issues recently. Due to not having an installation disk or a usb with Windows on it. I've seen videos and other answers showing how to factory reset, but not without removing Windows too. I'm very untechy. Searched about a bit to no avail, so sorry if this has been posted before. Thanks ahead.
