a few days ago my logitech wireless keyboard started "coughing".
Now I'm trying to figure out why and the windows ressource monitor reveals that svchost.exe is permanently using 1 core (25%) for itself. So far it's been either wuauserv or ssdpserv. Restarting the service doesn't help.


Edit: Even when I stopped the service it still used 25%!



Now I'm trying to figure out what causes this and of course a solution.


Same for the keyboard issue, if those are not connected. (New battery, driver updated, tried a different usb port).


I suspect a failed Win10 upgrade might be the cause. I started it from within windows, it took quite long and in the end it failed telling me it's reverting to Win7.


If I don't find a solution over the weekend I'll just restore a disk image of July 3 - I tried to upgrade on July 4.


thanks for any suggestions,
