PCmover Windows 7 Upgrade Assistant
Full user review
"Haven't tried it, but documentation informative anyway."
Documentation identified things I needed to learn about, be aware/careful of when upgrading from Vista to Win-7 (whether I use this tool or not).
Not used yet thus zip so far ... so rated it a 4 because it least is seems to be better documented than many free toolsets.
Since I have not tried it, I can't really speak for the product itself but but reading the documentation I at least learned a few things that I should do/not do when upgrading. Note: I've done an XP to Win-7 upgrade (without a toolset) and it was a long process due to having to copy/reinstall lots of software, etc., so I would hope that if you followed the advice in the documentation using this toolset could/would simplify (if not speed up) the process a bunch.
