I have Windows 10 Pro x64 installed and recently after a Windows update, the default plugins are all disabled. They are not greyed out, I cannot check to box to activate them. Out of all the plugins, I use the SevenDex plugin which shows the current active desktop number on the taskbar. If I uninstall Dexpot and reinstall, all is good. Turn off or reboot the computer and the plugins become disabled again. Not sure if this problem has been reported yet.
