Didn't try Tenorshare, but I did try a few others. As I replied above, the trial-versions only searched so far before telling me that I needed to buy the "full version". Understandable since they are in the business to make money. Besides, the PW I forgot was quite long (15+ characters) that used lots of symbols so I didn't think too much of this.
That is until just as a lark I changed my PW to "go" and then tried to use the same trial versions again. All of them after a few seconds got the PW but only showed me the "g". They said that I needed to purchase the "full version" to find out the last letter. Again, I understand that they are in the business to make money, but that seemed a little lame.
So I decided to save my money and invest in a pen and some paper instead.
