So i installed something on my pc and it changed my windows license key is there anyway to get it back. I cant use system restore as it failed everytime so i used sfc / scannow to fix that but it deleted my restore points.

have you a copy of the Product key?

Unfortunately No never thought about writing it down.

In most cases there is a sticker on the case of the laptop/PC with the key shown on it. Have you looked for a sticker?

  1. Open an elevated command prompt.

  2. type slmgr /upk and press Enter to uninstall the product key.

    will remove the new product key reboot the PC

your windows 10 key should be saved on MS servers and so should reacivate when connected to the internet. if it doesn't and you get activation errors then see click here

Not sure what you've done but if activated via Key Management Service server it might only last 180 days.
