PresentationFontCache.exe Consues High CPU Usage
» PresentationFontCache.exe uses 50%+ of my CPU and therefore my 64 bit Windows 7 system runs even slower than it did with Vista. Is there a fix other than killing it every time I boot up?

you may use view hidden files and then you will see it for your prob. I suggest to open your windows task manager and terminate the "presentationfontcache.exe", you will never have this annoying problem any more (CPU usage 100%)

- DEH SIGEE replied on March 20, 2013: » It's grabbing large CPU because it is rebuilding the cache. When you first install or upgrade .net no matter which parts. the .net assemblies are rebuilt.
This process does need to complete and shouldn't be interrupted. you can however negate issues with the cpu by changing the processes cpu affinity. using task manager right click the .net process that is hogging the cpu and change its affinity to below normal or lower. This essentially sets it to a background task and lets the rest of your applications have priority.
- M SCHMIDT replied on March 21, 2013: » As you know now that presentationfontcache.exe is a part of .net framework 3 and it is very much required for some applications to work properly. You should not disable it as it is highly recommended to run it. If presentationfontcache.exe is using very high CPU then you can try killing the process temporarily, but please note that it will start automatically after some time.
