I have disabled everything and don't use a background scanner. Windows
Update Advisor says that my system is fully supported by Windows Vista
including Aero user experience. Maybe dmex is right. Most application
I have used today were faster than yesterday (only 50% CPU usage).
Only Terratec Home Cinema is still unusable but this could be a bug in
their software. I seems that this is the first version of Windows
which gets faster every day.

Regards,
Stefan
