Download USMT 4
USMT 4 x86
Microsoft decided to incorporate USMT 4.0 into WAIK which is over 1GB download. I have stripped out the USMT 4.0 binaries, manifests and templates and created a new MSI install.
All installed binaries are digitally signed by Microsoft.
Download the repackaged Microsoft's (c) USMT 4 command line migration utility.
