Windows 10: Windows activation key says it has already been used

I just received a new windows 10 key from my organization, but it says it has already been used. They said this is an error that Microsoft could fix.

windows 8 activation key

You can use a Windows key as many time as you want provided it's only on one computer at a time. If the automated activation fails, just call the number it provides. Six minutes later, you're activated again. If it asks you how many computers it's on, just say "one" and you're golden.

 

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.

 

Windows no longer active it says windows not activated.
