Somebody helped me 2 years ago to install MS Fligth Simulator.
This guy made me create two entries into XP just after starting the PC.
One entry is the normal XP used as usual and the second entry started also XP but with many services disabled so that the Flight Simulator had more resources and memory for itself.
With my bad (human) memory I don't remember how I did that. Could somebody help me ?
After lot of searching I think I know which services can be disabled for FS.
