You can remove: Languages: more of them if you click the + sign, only keep the ones you really need Multimedia: DirectX diagnostic tool- not needed for DirectX to function Network: NWLINK IPX/SPX/NetBIOS protocol unless your on a newtware network Operating System Options: Disk Cleanup and ZIP Folders (if you use another program like winrar, winzip, 7zip) Services: Beep Driver, Secondary Login (unless you use fast user switching), TCP/IP NetBIOS helper (very old from win3x days) Personally, I'd keep the Command Line Tools, and play with 16 Bit Support. If you find no games that need the 16 bit support during testing, then leave it out. Alternatively, copy the command line tools you want to keep to $OEM$\$$\SYSTEM32 folder of your CD from a working system and remove them in nLite. Ping for one is very handy to have for gaming. One way of making sure of 16 bit support, keep an eye on task manager while using your system, look for anything listed under 16 bit subsyste, and for WOW (Windows on Windows).
