Will I have to buy windows again for new mobo cpu and ram

[SlimeMaster]

So I have a prebuilt system well kind of custom made by places like cyberpowerpc or origin like that. Anyways I will be upgrading my mobo, cpu, and ram. I checked in my settings and my windows 10 isnt digital it's OEM. So if I upgrade will I have to buy another windows 10 or just reinstall?

As far as I understand, OEM Windows license is tied to the MB. So yes, you'll have to buy a new W10 license if you change it.

If you dont have the Windows 10 licence key on a sticker, you could try retrieving it using the Get Windows Key.vbs file which is a Visual Basic Script text file with the .vbs extension whiich when run (double clicked on) it will retrieve the code for you and display it on screen. You could then do your rebuild, enter the key and cross fingers it re-activates.
WARNING: Ensure you source the vbs file from a trusted source or copy the code from the site and paste into notepad and save it with a .vbs extension
