I recently bought a new pc and everything was ok with windows for around 2 weeks. Now I have an Activate windows watermark on my screen all the time and the activation tab says ''We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.''. My pc has never been in an organization I just had a guy assemble it and I bought it. Tried running slmgr.vbs /dlv but that says im running a non core version of windows.
