No compatibility wizard in win2k. Win2k was originally NT5 but microsoft prolly didnt finish winME in time for the 2000 release so they renamed NT5 to win2k. Being an office OS based on the NT kernel win2k lacks DOS resources needed for (at the time anyway) many PC games. If you ask me..and I'm sure noone does..winXP is yet another slowed down OS by all its bells and whistles like the win9x tradition way up to winME and just getting worse. Dont mind me..I need coffee :)
