I have the same feelings. I downloaded a prior version from Giveaway of the day and am also perplexed by it. I really want to use this as a backup/clone to my entire Win 7 drive. Several years ago I was burned (literally) by a CPU and motherboard overheat and lost everything. I guess because the backup software (Aomei, EaseUS) tied the clone image to the CPU serial number (?) and I couldn’t load it onto another computer/drive. Took months to start over.
I did notice when I went to the about file in my old version it showed something like Machine Code: 000B8C3A029A392… and I wonder if that might be my CPU serial number.
I don’t like to post links on forums like this (promotion, spam, fake etc.) but you can search for the mentioned give away site and then for WinToHDD and read user comments on the 3 versions listed. We have several days to work on this.
