<human>: Can you give me a shortened version of the text?

This happened a couple months a go, yada yada

So I was checking my computer one day and realised that my SSD had been filled to the brim with random shit that I didn't need, and so was my Hard Drive, so i though to myself "Fuck it, i'll take it back to factory settings." Now me being pretty shit with computers when I was resetting it I ticked some option that deleted EVERYTHING from my computer, including Windows 10. So I am panicking playing in the BIOS, again I am pretty shit with computers, trying to re-install windows and all that. About two hours had passed, mostly on tech support in order to get my CD Key back (I still had the windows 8 disk), but I decided I'd just go buy Windows 10. I bought a Windows 10 USB with ease, but when I was installing it, the CD Key wouldn't work. I spent another couple of hours on Tech support to try and solve it only to be told my computer was broken. So I packed up my computer to take it to the store when my mum notices a little sticker on the side of my desktop that has a Windows 8 CD Key on.
<bot>: Tried to clean my computer, unisntalled windows, bought Windows 10, found out the CD Key for windows 8 was next to my knee all along.
