I just found that Windows Update is failing and hasn't installed any updates for a little more than a month.
It says:
Windows could not search for new updates
There was a problem searching for updates
Errors found: Code 80244019
This article at Microsoft suggests it might be a virus: Windows Update error 80070422, 80244019, or 8DDD0018
The operating system is Windows 8.1 Pro with Media Center.

What worked for me was going into services.msc and restarting the 2 services bits and windows update services; Background Intelligent transfer service.
