PC Magazine's 91 Best Windows Utilities
These utilities are carefully organized into categories, as they should be, such as Appearance (which includes such things as Taskbar Shuffle); File Transfer and Backup. In each category are at least one or more free gems, as well as one or more pay programs. I guarantee that there will be at least one in each category that you have not heard of. I was surprised at how many were new to me, and it might take some time to experiment with all of the new ones. Hopefully you have a computer that you can experiment with, because there is certainly a lot here to try out. Have fun, and please share with us the ones you like best.
