How do I activate Windows 10 if not activated?
Windows 10 can be installed without a key, but you won’t be able to activate without a valid license. Here’s how to get around that.
If you’ve installed Windows 10 without a key, you won’t be able to activate it. However, there is a workaround. Here’s what you need to do.
First, head to Microsoft’s Activation in Windows 10 page and scroll down to the “Get help” section. Next, click on the “Contact us” link.
Microsoft’s activation servers will then attempt to verify your key. If they can’t, you’ll see the phone number to call displayed on-screen.
Once you’re on the phone with Microsoft, simply tell the customer service representative that you’re trying to activate Windows 10 without a key. They’ll then give you a activation code.
Enter this code into the “Activate by phone” section of the Activation page and you should then be able to activate Windows 10.
If you’re still having trouble, you can always try installing Windows 10 with a valid key and then upgrading to the free upgrade. This should work, but it’s not guaranteed.
So there you have it. If you’ve installed Windows 10 without a key, you can still activate it by following the steps above.
