Typing IEXPRESS.EXE in the command box launches IExpress 2.0 wizard to let you create an installation package.
I wonder if I'm the only one that didn't already know about this...
[Update] This exists in Windows 2000 as well as XP. I don't know anyone with win98 that can check for IExpress there.
Awesome. I'm still trying to figure out what this thing does... maybe I can use it for a quick and dirty .NET installer?
