I am not able to find site where to download ms Powerpacks 10, I use it with vb.net 2010.
Microsoft.VisualBasic.PowerPacks.Vs 10.0.0.0 is included with Visual Studio 2010.
By default located C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\VBPowerPacks\en\VisualBasicPowerPacksSetup.exe
