How to wipe your computer?

Hey guys I have two computers I plan on botting on but unfortunately at the moment they're pretty slow due to things on them. Is there anyway for me to entirely wipe the contents of the computer without getting rid of the actual operating system and having to buy a new one? Would this clear any potential viruses/ect that could be limiting my computers performance? Any help is appreciated. Thanks

Can you just restore it to manufacturing settings?

Re-installing the os is the best way to get a complete wipe and fix any corruptions.

Find the license key to your operating system. It should be on a sticker. If it doesn't have one, it's still possible to find it

If you have the key but no windows media, you can download the windows iso (legally) and do a fresh install via usb. Make your install disk with any number of programs. I recommend rufus. Boot from your usb and enter your key when prompted.

 

If you're botting and the bot works on Linux, you should install Linux from a clean boot. My absolute favourite distro is Xubuntu, I run it on 2 of my machines. It'll wipe your computers and make them much much faster.

With one of these of course;​

I'm only kidding, just like everyone else has said. You can reset your computer back to manufacture settings BUT you'll have to reinstall everything you had previously downloaded.​
