Part of the .Net Framework - if you use Windows Media Centre, XBMC, or stuff like that, it can remain running in the tasklist, even when the program which invoked it exits. See This Thread at Microsoft

It takes100% of my procesor, it dosnt start everytime and if i kill it, theres no change (just my PC run much faster), for me its a unwanted program
Original text from Windows XP: Optimizes performance of Windows Presentation Foundation (WPF) applications by caching commonly used font data. WPF applications will start this service if it is not already running. It can be disabled, though doing so will degrade the performance of WPF applications. Enter 'services.msc' from your Windows installation.

taking 50% cpu - I searched for font*.dat and deleted - restarted and it is now gone.

Appears to help programs that run off the .NET framework run a microsecond faster
Causes CPU to get bogged down. Had it running on my Duel Core CPU at 62% or higher and slowed my PC down considerably! Killed it with the "Security Task Manager" link above and it stopped it for now and my CPU is running normally now. I have the feeling it is a Virus.

I think it's part of NET 3.5 - it showed up on my system when I installed JING to do screen recording. Once you unload JING, then you can kill it using task manager
this file helps .net 3.0+ apps start slightly, but not enough to warrant keeping it, disable it, keeping it running doesnt make things happen that much faster and often causes more CPU issues, is it dangerous, not really no, but the lag might make you pull some hairs from your head
This is a Windows file; unless there is some problem with it (e.g. it goes crazy and eats up your CPU) you should leave it alone. It's not essential, but it is beneficial.
High CPU usage when not disabled 50% CPU usage with dial pentium 4 under windows XP and nothing running. Is a real pain when running high CPU apps such as Rybka chess engine
It is safe and needed.
It is an official Microsoft application and is harmless, it is not critical to the operation of Windows and can safely be disabled if needed.

I run scannow and get this error: CSI 000001a2 [SR] Cannot repair member file [l:64{32}]"PresentationFontCache.exe.config" of PresentationCore, PublicKey neutral in the store, file is missing 000001a3 [SR] Cannot repair member file [l:64{32}]"PresentationFontCache.exe.config" "PresentationFontCache.exe.config"; source file in store is also corrupted SO, HOW REMOVE IT THIS CRAP? ANY IDEAS!
PresentationFontCache.exe started slowing my windows 8 computer down. Always grabbing 49/50% cpu. I have good anti virus checkers none found anything, but who knows? Deleted every sign of PresentationFontCache.exe from the registry and then task manager. Everything fine now, no more high cpu, back to normal speed with computer. As far as I am concerned, get rid of it.
I'm running Firefox and have it "disabled" as an add-on. It's running, anyway. I'm trying to figure out if it's behind my slow-downs and hang-ups, but the Task Manager won't open until whatever's slowing it down gets done, so I can't be sure of the culprit.
PresentationFontCache.exe uses 98% of my CPU on Windows XP starting...:(
It is highly annoying and slows my computer. Have to delete / stop running in task manager twice before it disappears. Slows computer down with over 50-60% usage resulting in dead stop computing.

I know nothing of PresentationFontCache.exe but am a programmer. It is most likely a safe program, but it is possible a virus replaced it with it's own copy. Judge based on whatever data you get (chewing memory, outbound connections from process, etc.) but basically I think it's just a bug in the code... I make bug all the time, some of them are easy to miss...
It slows down AutoCAD

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
