Not directly related to SLSK, but when i still used windows a couple of decades ago, id backup my profile and move it to the new machine so i would retain everything of 'mine' and not have to set things up one by one, and risk loosing stuff. I would assume any SLSK settings are down in there so they would come across.
On UNIX, i do similar, my entire home folder is backed up and restored, which is basically the profile in windows ( settings, files, desktop, bla bla )
