Looking in Task Manager, these two singled themselves out as very CPU-hungry, taking up 50-100% between them:
I found a working solution that suggested disabling three WMP-related services.
- Open the Start menu, right-click on Computer and select Manage
- Go into Services and Applications, and then Services
- Locate the following services:
- Windows Media Center Receiver Service
- Window Media Service Scheduling Service
- Window Media Player Network Sharing Service
- For each of those services, in turn, do as follows:
- Right-click on the service’s name and select Properties
- For Startup type select Disabled
- Click OK
- Close the Computer Management window
After I did this, my computer has been far better behaved. The ultimate step would probably be to uninstall Windows Media Player completely (or rather disable it, as I don’t think it can be fully removed from Windows, much like Internet Explorer), but I like to keep it around in the unlikely event that I might find myself in need of it.
