I downloaded your program and took a brief look at it.

Not a big deal, but on the Service Pack screen maybe you could populate each field with only the available Service Packs based upon the selected OS. i.e. Windows 2000 does not have any SP above 2 at the moment and NT 3.51 quit around 5 I think.

How can you do custom things like search for files and take different actions based upon the results? How can you check file dates and compare? How do you check IP address and split it up into octets? etc... Maybe I'm overlooking the obvious.

A screen resize would be nice also. I use 1600x1200 and the program is a little small. Not bad, but still small.
