Does somebody knows how to disable animation in WPF ProgressBar (Windows 7 and Vista) because it is very CPU intensive, especially when many of them are displayed at the same time. But I do not want to disable it system wide, only in my C# application.

It's not the ProgressBar that's cpu-intensive - it's your code. If you want to prove that theory to yourself, simply comment out all of the calls to all of your ProgressBar controls.

Jogn Simons, even using an i7, cpu usage of 3 progressbars hits 2% (1 progressbar 1%)

Dizz, here's the solution for cpu usage. It only animates when IsIndeterminate == true. The RAM usage doesn't change :(
