is there a program that replaces explorer.exe?

Submitted by SDMA on September 14, 2007 - 3:01am.

I noticed that i can close explorer.exe and my computer still runs, there just isnt a program to handle the icons or to organize the open programs. Is there some kind of program that replaces this and maybe has more features, like a mac style or something? Just wondering because i know there is style XP which just changes how the PC looks. Thanks.
