DO NOT install WAIK on a functioning VS2005/TFS RTM computer…
The .NET FX version WAIK uses will fail during install and leave VS 2005 unusable.
Note: You can fix the computer with a repair of the .NET Framework 2.0 but you probably have better things to do with that time.
For those of you that haven't heard of WAIK it is described in MSDN downloads thusly:
