PresentationFontCache.exe uses 50%+ of my CPU

Anonymous

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?

Hi,

the service PresentationFontCache.exe is only usefull if you use WPF (Windows Presentation Foundation) applications. If not, start services.msc and disable the service.

Worked perfectly with Windows 10 x64 as well.

note - Most users will have to navigate to the folder using windows explorer (vs using run command) to avoid getting a permissions error

As twsGumby has directed in other threads, this thread seems to offer another way to deal with the behavior:
