Microsoft - PresentationFontCache.exe

The genuine PresentationFontCache.exe file is a software component of Microsoft .NET Framework by Microsoft Corporation.
"PresentationFontCache.exe" is by Microsoft Corporation, a Windows service from the Windows Presentation Foundation (WPF), the graphical subsystem of version 3.0 of the Windows .NET Framework. The WPF has been an essential component of Windows since Vista. Although the subfolder "C:\Windows\Microsoft.NET\Framework" may have multiple version subfolders, only "…\Framework\v3.0\WPF" contains this program, accompanied by "PresentationFontCache.exe.config". This program has no visible window. The first WPF program to start after rebooting, (which can involve substantial overhead), once running it improves performance of applications using WPF by caching the system fonts. Frequent complaints about its elevated CPU usage can sometimes be addressed by stopping the service, deleting the file "Windows\ServiceProfiles\LocalService\AppData\Local\FontCache4.0.0.0.dat" and restarting it. However, it can cause high storage consumption by creating 8MB "per-user" cache files; high user volume on a server may create more than 50GB of these. Founded in 1975, today Microsoft is the world's largest software producer by revenue.
