I have used windows live photo gallery for a number of years, tagging, commenting and organizing my photos.  I want to continue on my new computer however the download is no longer available and it is no longer supported.  I am extremely disappointed because I have spent countless hours tagging and commenting on my photos.  Does anyone know:

1. How to download it to my new computer or get it from my previous computer?

or

2.  The best alternative to tag, comment, organize, etc.?  Another program would need to be able to see and use the tags I placed on windows live photo gallery.  

It is the tagging and commenting that I need.  

Thanks.
