I used this product to transfer files to a new computer I had put together. I used the same operating system, Win98 SE. The program froze up a number of times. I was able to transfer most of my files, some of my applications. The problems is, when it freezes up, it starts all over again rather than being able to see what has already transferred. At one point, with just a few minutes to being finished, it was merging my old registry data with the new and froze up again. Very frustrating! Also, on a previous freeze up, the target computer would not boot fully, even into safe mode. I wound up having to revert to a previous system configuration. I would not recommend this program to the average computer user. You could wind up getting into a situation you may not be able to fix.
