Hello,

I have Windows 7 OEM installed on my computer.
Since I got a new SSD, I thought to install WIndows there, too (not cloning my drive), so I want to ask if it is ok with MSFT for me to install Win 7 OEM on 2 drives in the same computer, or even better, Win7 OEM on one drive, and Win 10 (based on the Win7 OEM license) on the SSD.

Thank you

It will work for 30 days, after that your Windows 7 Key will become invalid. But there really is no reason to keep Windows 7. I know, I know we all like it and familiar and all that. If you want to wait for all the bugs clear out you have until 6/20ish next year to upgrade.
