What to do?

[Kunal Das]

I just purchased a Windows 10 Pro key from ebay for around $1

 

After activating, and checking it with

slmgr.vbs /dlv

and

slmgr /dli

, it returns the key as Windows 10 Pro VOLUME_MAK key. However, it is attached as a digital key to my Microsoft account.

Now the ques is:

 

1. For how long a MAK key can run, given that seller is listing the key as brand new and sold only once key.
2. What if I want to reinstall Windows 10 Home, which came preinstalled with my laptop and sign in with Microsoft Account, will it create an issue in activation?

After some research, I think MAK keys expire on the key itself, the install just runs out of uses for it and cant use it to set up. I don’t think it will remove from your device.

However on running 

slmgr /xpr

it returns Windows is permanently activated.

So then you won’t have to worry about the key stopping working in the future.

It turned into a Retail key after I reinstalled Windows 10 Home, Entered the upgrade key, and signed in again.
