Hi I have found out that PresentationFontCache.exe is using 50 % of CPU usage all the time.
I really want to stop it..
I have disabled the .Net framework 4 etc from the services.msc etc and still comes up.
I dnt want any answers with how important it is.
If you know how to stop it..please let me know.
Go to control panel, Administrative Tools, then Services, and find that service (Windows Presentation Foundation Font Cache 22.214.171.124). Double-click it to open its Properties dialog, and change the "Startup Type" to disabled.
