I run into the issue where Windows update is no longer working (keeps searching forever) and the CPU usage is at 50%. I found that others encountered the same issue on this forum. However, it was not clear to me what the solution is.
I had the problem previously in which case a reboot and time seem to have resolved the issue. No longer.
I kept the PC up-to-date so far. However, I had to uninstall two updates to enable a function that MS eliminated.
(KB3185330 and KB3108699.). The feature it disabled: hosting IE inline a Silverlight app within Microsoft Media Center).
Does anyone know how to fix this CPU usage issue? Other than disabling Windows Update?
