Windows 10: OEM Windows 10 activation key won’t activate on rebuilt Parallels Virtual Machine

I am running a virtual PC on my Mac Mini using Parallels. I purchased a WIndows 10 Pro OEM activation key which has worked perfectly for over a year. The virtual machine crashed and I needed to rebuild it. I now can’t active the same key that I have been using up to now. I get a message “The product key you entered didn’t work”. Same host machine.Help!

Parallels virtual machine

I installed a Parallels virtual machine onto my MacBook pro. I used my windows 10 License key to activate windows.

The virtual machine became corrupted and had to be deactivated and removed. Now I cannot log back into my windows account as my license key is still logged against my deleted parallels virtual machine. Is there a way to overcome this?

 

activate windows 7 oem key

There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating it.

 

oem activation key

I have a window 10 os oem version. I want to do a fresh reinstall on my computer. Can I use the same activation key ( i used in the first place to get my pc up and running) if it has been used before.

Note: I will use the same cd and the key
