ehrec.exe using up CPU

Posted by admin on September 24, 2010; This entry is filed under Uncategorized.

Had an issue today with Windows Media Center where ehrec.exe was using nearly 100% CPU shortly after the PC had started up. In addition to this, after the desktop appeared, there was a 2-3 minute gap before any applications could be used – for example if you ran internet explorer, it would not open for about 3 minutes (or untill the networking icons showed up in the task bar).

Anyway, after a bit of research and troubleshooting, it turned out to be and update from Microsoft – .NET Framework 4 Client Profile (KB982670) that seems to have a bad reaction to ehrec.exe (apparently a component of Windows Media Center that controls TV recordings???).

Once this update was removed, all works fine. Apparently this issue only exists in Media Center – HOWEVER, this isnt the first time the NET Framework Client Profile has come up in conversations regarding a Windows issue. So I will be marking that update as “Don’t show again!!”.
