Why does my laptop say: "We can't activate Windows on this device as we can't connect to your organization's activation server. Make sure you're connected to your organization's network and try again. If you continue having problems with activation, contact your organization's support person".

I have similar problem but with Windows 8.1
After I installed Windows Update updates and rebooted it says Windows is not activated but when I click activate it throws error without any error code. And it placed the "Windows 8.1 build 9600" watermark on my desktop. Any way to fix it?
