    DEactivation?


    I ended up with a crippling infection on one of my two laptops. I Dban ed it and reinstalled from scratch, but it wouldn't accept the product key that came with the laptop (pre-install), so I entered the key that came with the disk which I bought (Win 8.1 home). I bought the disk for the purpose of reinstalls, and the key I used pre-install is the key being used by my other laptop. When I tried to switch keys on my other laptop, it said that key was being used by another computer. Do I have to de-activate the key or something? I have two legit keys and two laptops, how do I make this work?

    Don't use the same product key on two different computers.

    Windows 8 and windows 8.1 are two different operating systems which require DIFFERENT keys. An 8 key will not work with 8.1. I would guess that the key that came with the laptop was a windows 8 key only.

    This means you will need the 8.1 key that DIDN'T originally come with the laptop. It may be that Windows allows you to enter the old 8 key on the 8 operating system before you upgrade to 8.1, but I am not sure about this.

    Other members may have more knowledge on key use, so hopefully someone will pop in here to give you a hand.

    An 8 key will not work with 8.1.
    I recently did a clean install of Win8.1 64-bit on a new drive -- and installed, and activated it, using the key that came with the original Win8 DVD.

    That is interesting! It used to be you couldn't, but I just found someone else that said you could too:

    Windows 8.1 is a free upgrade to all Windows 8 users, but you normally can’t install Windows 8.1 with a Windows 8 product key [...] Update! Microsoft Makes it Easier [...]

    An OEM embedded key being refused on install usually means your using the wrong install media. Example, installing Pro when the OEM key is for Core, or vise versa. Another gotcha is if the OEM version is Single Language. If you try to install the normal Core version it will reject the Core Single Language OEM key. I can confirm that the current Windows 8.1 install media will install with and activate with, Windows 8.0 keys, even OEM embedded keys.

    So, I got it to work by calling it in. I just had a brain fart. I'm actually down a key, as both laptops (purchased new) came with windows, and I bought 8.1 home version to have the install media. The original key was lost when I had a crash, and I paid for the disk because it was the least headache at the time and I knew I would reinstall my other machine at some point as well. Appreciate the help everyone! Next time I'll try to be smarter.
