Here’s a third acknowledgement about this software. I also have been using it for years and have purchased and renewed. It keeps my computers clean by fully removing the remnants of all these free to try programs after the licenses expire. Sometimes there are hundreds of leftovers! One can also check if any unwanted changes have been made. Yes, it is a time-consuming extra step, but when one wants to get a new version of something one does have to fully remove the old version and license sometimes. I recommend it.
