Okay so I have tried litrally all the ways to activate my Windows 8.1 Pro 64 Bit Build 9600 and none of them are working. I really need to activate this. Can you guys please help. For Microsoft Toolkit I get an error that says product key not found and for KMSSpico it just says product activation failed and I have tried numerous other methods off YouTube and none of them work for me. I can do a TeamViewer session if anyone wants to help me.
