The Windows Presentation Foundation Font Cache service optimizes performance of the Windows Presentation Foundation (WPF) application by caching commonly used font data. You may have multiple versions of this service, such as Windows Presentation Foundation Font Cache 3.0.0.0 and Windows Presentation Foundation Font Cache 4.0.0.0, to support applications that are created with different versions of WPF. WPF applications will start this service if it is not already running. It can be disabled, but doing so degrades the performance of WPF applications.

This service is installed by default in Windows 7, and its startup type is Manual.

When the Windows Presentation Foundation Font Cache service is started in its default configuration, it logs on by using the Local Service account.

The Windows Presentation Foundation Font Cache service is not dependent on any other system service, nor is any service dependent on it.
