Re-imaging Windows Pro

I get asked this question a lot: "How can I re-image my Windows 10 Pro OEM machines with Windows 7?
The answer is with volume licensing.

All you need is a single Windows Pro volume license to be able to re-image your machines with Windows 7 Pro.

There are a couple of agreements you can do this through.
1. MPSA
2. Open

MPSA is really only an option in this scenario during the first year of your agreement. This is because after the first year Microsoft adds up the number of points you've earned in the systems pool, which is the pool that includes Windows Pro, Enterprise, and VDA.

If you haven't been buying those products, Microsoft would put that pool on hold and you'd be unable to purchase a single copy of Windows Pro on your MPSA.

Open is the most likely program that will work for you in this scenario. If you have an active Open agreement you can simply purchase 1 copy of Windows Pro.

If you don't have an active Open agreement, all you need to activate one is to purchase any 5 licenses. That includes server and CAL licenses, application licenses, etc...
