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
  Ray  
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
  Jenna  
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.
  Locke  
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
  ClarkDMerrifield  
It is safe and needed.

Best practices for resolving PresentationFontCache issues

A clean and tidy computer is the key requirement for avoiding problems with PresentationFontCache. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

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 resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the PresentationFontCache.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
