Windows 7 activation key blocked by Microsoft

Hi, I'm trying to activate using my product key. But Microsoft blocked it. What should I do?

If you bought a product key by itself, most likely it is pirated, as Windows 7 product keys were not sold by themselves.

If it came preinstalled or a Retail Key contact Microsoft:

Contact Microsoft:

Activate Windows 7 or Windows 8.1 - Windows Help - Microsoft Support

When you begin activation, Windows will try to use your Internet connection to activate online. If you have problems activating online, you can activate using the phone.

If you have to use Phone Activation, read this detailed information about using that method:

If OEM preinstalled (Dell, HP, etc.) license:

The COA sticker, which has the Product Key on it, is either on the underside of the Laptop or in the Battery Compartment.

With a Desktop it is either on the side, rear or top of the Computer Case.

If you have problems using that method contact Microsoft Support:

To contact Microsoft Support:

I only get the "go online and resolve" option. So what should I do?

Contact Microsoft.

We don't work for Microsoft and can't activate it for you.
