Not really a Windows Mobile tip but...

May be everyone in the world knows about it, even Pluto who lives next door.

I frequently need to look for "Microsoft ActiveSync" or other programs in the Start -> Programs list on my desktop PC. With the number of applications installed, this activity resembles a treasure hunt. Not only for ActiveSync, but you can sort the programs in the Start -> Programs list. Just go there and right-click and select "Sort by name". All programs are then listed alphabetically (folders first and then short-cuts). Really makes searching apps easier.
