Dllhost.exe Memory leak

I'm often experiencing memory leaks from dllhost.exe. this happens most often when I'm runneing µTorrent, but also when I'm running spotify.

 

I'm running windows 7 x64

 

has anyone here experienced the same thing or know how to fix it?

 

Thanks.

I seem to have found a solution: windows update KB2670838, kill it with fire!
