Most noticeably I use VLC, can't live without it anymore. Windows media player is such a piece of junk. Then install MS Word and Excel. uTorrent is also among the few applications I can not live without. Need silverlight for Netflix and install WinRar only if needed(which is seldom anymore). I also install AVG free antivirus and dropbox is always a happy addition. Backup this restore point so trying out new apps won't bog down my system to unusability over time. Cheers!
