I think you missed part where OP says he has bought another cheap windows 7 key (Quote: so I bought another really cheap Windows 7 key), so would be in 100% compliance.What Microsoft will physically allow with no problems at all is a completely different subject than what violates the EULA or not. I have multiple licenses for Windows due to purchasing a 3 license family pack a while back and then subsequently upgrading those computers to new, off the shelf computers with their own OEM licenses for Windows. I'm running multiple copies of Windows on one computer - but the thing is with the new digital licensing for Windows 10, my multiple copies of Windows installed on the same computer have no unique product keys associated with them. They have now all been clean installs at some time in the past which were done by skipping the product key and then activated with the digital license that was first created from upgrades from Windows 7 and 8 installs.
Multiple copies of Windows on the same computer will not cause any activation problems at all and they can all be activated with just the digital license stored on MS Activation Servers. But in order to comply with the EULA, I have a listing of my retail product keys stored in a text file, each product key represents either 1 license for Windows, and a couple of the product keys represent a 3-pack family license for Windows. But Microsoft does not even treat the 3-pack family license product key any different, when I was using it for the Windows 7 it was meant for, I still had to call MS to activate Windows 7 and lie to them and tell them it was installed on only one computer even though I was in full compliance with the EULA to have it installed on up to three computers.
