Solve "PresentationFontCache" (.exe) taking too much CPU

After working on a project on Visual Studio 2010, I faced an issue where nearly 25% of my CPU (i7 M620, Windows 7) was being taken by the PresentationFontCache.exe. This service is used by applciations that use Windows Presentation Foundation (WPF) but many a times I was not even using a .NET applicaton (rather I was working on Java !!) and still teh PresentationFontCache.exe was hogging my CPU.

After some search and analysing multiple possible solution running these command and rebooting solved my problem on my Windows 7:

cd /d C:\Windows\ServiceProfiles\LocalService\AppData\Local\ del Font*.dat
