There's lots of free software out there, thanks to the open-source movement. But there's none that can transfer programs, data, and settings to a new Windows computer as well as PCMover. And the $50 program is free to download today, if you've got patience to get through its website, which is very slow today.
Demand might ease this evening. The program's author, LapLink, is making the offer through midnight Pacific time to celebrate its 25th anniversary.
Or, I found the process much quicker if you're willing to also buy something from the LapLink store. That raises a bit of suspicion of a come-on, but LapLink is a credible company with servers that I'm sure are hammered today.
I found PCMover to be a good download if you're trying to set up another PC. That's true at its normal, $50 price—and even more so with today's one-time free download.
