Microsoft Bob - A failed attempt of Microsoft at creating a "user-friendly" software. Rare to get now. It was developed it the 1990s. Search for it and if you can get it, do try. Little kids will like it, as it will be a fun way for them to use your computer.
RiverPast Video Cleaner Pro - What I use to convert videos from one format to another. User friendly and straight forward. For simple as well as advanced users.
Windows Defender - Anti-spyware for free, from Microsoft.
MidpX J2ME Emulators Package - Play Java mobile games on your computer! (also Midp2Exe)
MatchUp - A concentration game from Microsoft.
And of course, Vista Transformation Pack (see last post :)
