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.

    PFC has been running constantly for the last three months straight.  I have checked it once every hour for 8 hours a day.  It seems every time any of my applications or windows gets an update a rebuild is required.  It seems to take about 72 hours of runtime to rebuild the cache on a quad core i5 3230.  It then shuts down until my next update (usually with in 24 hours I get some type of update to something and it fires off again.  Over the last 30 days when I have checked it at all ours of day and night at least 8 times a day it has been running for 96% of those checks and average 30% of my CPU!.  This is ridiculous.  Unfortunately I have mostly WPF applications running so need to have this process running.  If I just wipe out the fonts as is suggested within an hour the WPF is running again to regenerate them. I am at the point that I will have to  upgrade to a i7 6000 series with eight cores and 15K RPM drves to get enough processing power for my apps and the font cache to run at an acceptable performance level. $2000 for the upgrade. Essentially I am adding in 30% more processing power for the font cache to run.
