I know of many people that use the Paragon stuff.
I've been using a paid version of Partition Commander for a long time. One of it's myriad of toys is a stupid fast way to find/resize partitions on drives, and set things up for a quick image of any drive on the system. I have a fresh blank drive ready to go for the upgrade. Toying with the idea of doing an image to the new drive first, then upgrading on top of it.
The new drive is bigger and faster than the current boot drive running Win7Pro 64bit. Imagine that.
That's the main PC. I have a laptop ready to go, and my wife's laptop as well.
One other Win 7 Home edition won't agree to being a real copy of Windows.
Working that out with MicroCenter, it's one of their refurbs with an OEM version of Windows.
