I have read numerous times that you are able to register windows 10 with either a windows 7 or windows 8 license key that has never been activated, or with a windows 7/8 VLK.
I currently have several legacy test machines running MSDN copies of windows 7 ultimate. The "free upgrade" window to win10 has come and gone, so I don't believe I can install windows 7 and upgrade to 10 through that path. So, I am looking to wipe one of the machines, and get it running windows 10 directly.
I know MSDN is no more, but the windows 7 license appears to work still. I also know that the MSDN versions of windows aren't an exact bit-for-bit copy of the normal versions (different OS media to install).
Does anyone know if you can use an MSDN VLK from windows 7 to register windows 10?
Just trying to figure out if I need to purchase a copy of windows 10, or if the MSDN keys we have will work.
