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.

  • The free upgrade offer expired on July 29th 2016. There currently is an upgrade offer for those that need special programs which expires I believe Dec 29th 2017. Will Windows 10 activate with your Windows 7 key, it will indeed activate, but unless you applicable to the current offer its ethically dubious to do so. "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)." - Yes there are The only difference is how they are activated which has nothing to do with the ISO being used.

  • @Ramhound till end of 2017 MS still allows using win7/8.1 key to upgrade to Win10. Nov 14 '17 at 16:47
  • @magicandre1981 - The current upgrade offer is only valid if you require assistive technology. You should also read what I said, I never said you cannot use a eligible license key to a previous version of Windows to activate Windows 10, I said to do so, when you are not eligible for the offer is dubious.

  • @Ramhound this is the official statement, but everyone is still able to upgrade Nov 15 '17 at 15:39

If you still have Windows 7 SP1/8.1 installed on the machines, you can try the Windows 10 upgrade for assistive technology users until December 31.

You don't have to enable the Accessibilities Features on the system. Download the executable, follow the steps and wait for the system update.

NOTE: First check the specs on the machines. If they are "older" is probably that they will not be able to run Windows 10.
