Microsoft Reader is designed to make your onscreen reading experience as close as possible to reading a printed book. In addition, it adds active reading capabilities, instant access to content, and a personal library. Features include high-resolution ClearType and an add-on dictionary, as well as the ability to bookmark, highlight, annotate, make notes and drawings, and much more. Version 2.1.1 includes a security update that closes known gaps in the Microsoft Reader security architecture.
MS reader is so easy to use and when you reopen it takes you to the page you finished so that you can go forward. Looks like a book and also keeps track of all of your books so that you can reread.
It is not compatible with windows 7.
I have used MS reader for years and it was fast and easy to use. you can switch settings as you need to. Downloads are easier than Adobe. I do not have any dislikes except that it is not available with MS 7. This is my favorite reading software.
