    I'm currently running Windows 7 on a 2012 MBP and I am considering upgrading my MBP so I would like to reuse the W7 key on my new laptop. It has been about 3-4 years since I last deleted the partition (had to increase the size back then) so I'm a little rusty on how I go about retrieving the product key so that it is usable again. Would I have to go into the Windows Command Prompt, or will the Windows Removal option on Bootcamp take care of that for me, allowing me to reuse the key?

    Many thanks!

    Just re-use the key on your new machine, typically as long as both Windows partitions are not running at the same time, Microsoft won't block the key, if you do happen to run into issues, just call Microsoft with the number provided on the activation screen, and explain to them that you bought a new computer and want to migrate it to the new machine. They do it all the time and it takes about 5-10 minutes (about 30 seconds of that is talking the rest is waiting).

    There's no way to deauthorize the computer, short of reusing the key and if need be, calling MS which is a simple and automated process. I did this myself a couple of times over the years and it was fine.

    I guess something must have changed over the years, because I know it was an option. I guess I will just call MS if there is a problem.

    I had to do it when I replaced my motherboard in my PC. When you select the Telephone method, it gives you a long number to type in to the automated phone system, which returns another long number to type in to Windows and you're good to go. Takes about 10 minutes.

    Yea. I figured it out. Doesn't require calling Microsoft. Just a few Prompt Cmds just to deactivate it.
