I have a Windows 10 Professional that needs to be activated. So far, I have tried both KMSpico and Microsoft Toolkit, but without any success. KMSpico said something about needing to reinstall Microsoft Office or open it for the first time. Microsoft Toolkit shows the error 'Invalid namespace'. When I open Windows activation, the following error is displayed *see attachment*. I have already tried the slmgr.vbs commands, but I got another error message. Do you have any ideas how to solve these issues and activate Windows?
