Not really a program but for those who don't have the Windows CD + Asian languages to play games/VNs; I uploaded my own file that I got from piratebay:

And if you want the torrent from the bay itself:

EDIT: When I installed it, there were some missing files but just keep installing it; in the end, I can read all the characters of any language.
Also;
CCleaner for those who need to clean their system, uninstall stuff, remove startups and etc. It's easy to use and lightweight.
