UHS Reader for Windows - description from Softdepia.com:
The UHS shows you just the hints you need to solve hundreds of different games. Most of our hints are available in two different formats -- the on-line ("UHSWeb") version, and a downloadable version. UHS Readers allow you to view the downloadable copies of our hint files, so that you can read our hints quickly and conveniently, without having to connect to our web site whenever you get stuck. UHS Readers also allow you to print out or search an entire game's worth of hints at once, making it easier to find the hints you're looking for.
UHS Reader for Windows is a "Free to try" program. You can download and try it for an evaluation period.
