windows activation

can i use my windows 10 digital key linked to my account

are you using the key on another computer, if OEM, is it retail or manufacturers oem? In general, if the key is currently not being used on another computer and it is not manufacturers oem, it can be use. There could be other exceptions too.

I have a problem to my windows and I want to reinstall it and It is just in my own pc, How can I finf out Is it retail or manufacturers oem?

if it came with the computer you are reinstalling on, there should be no problems. in most cases if you are reinstalling, you really do not have to worry about a key. Microsoft stores the original activation info so if you need to reinstall, it will auto activate.

The difference between manufacturers and retail oem is manufacturers came with the brand new computer - for example the OS on a brand bnew Dell computer. It can never be transfer to another computer. Retail also called system builders oem is what you buy when building your own computer. It is usually only good for a newly built computer.

It didn't came in my laptop at first I bought it from a website.
anyway, thanks a lot for your help mate.
