I used a special tool to crack the Windows 8 64 bit, it told me that my Windows 8 64 bit has already actived. and I checked the property of "My Computer", it really did.

But after one week, there was a popup windows at tray told me that I need to active Windows 8, there are only 22 days trial left.

How can I make a full Windows 8 64 bit activation?

Hi,

that is to say your windows 8 64 bit will be expired. You only have 22 left for the operation of it. You have to activate your win 8 for futher use~you should buy a windwos 8 activation key. Try it on microsoft.com to get the key.

Hi windows,

A windows 8 activation key can help you and you can get one on Microsoft.com.
