I'm looking into upgrading to Windows 8 from Windows 7 (64-bit) as I'm liking the various upgrades that Microsoft is making in 8.1 but I have a few questions before I commit. According to various upgrade tutorials I've seen, Windows 8 will keep any applications that were previously installed on the drive. However, I'm running a rig that uses 3 different drives (SSD for OS and choice applications, 1 HDD for music/documents/photos, 1 HDD for games) and was wondering if I'll have to reinstall or do anything with the applications/files on the non-OS drives.
