Hi, I've used this activator for Windows 8.1 Pro in a virtual machine for test purpose (as I had problems with Windows 8) and it works fine. When the activation term (180 days) expires, is it possible to reactivate or I would eventually reinstal the system and reactivate? I shoul be grateful for your information. Sully
Not sure what this is you're using here, but i recommend to get one of the official KMS Solutions like Microsoft Toolkit or KMSpico .
