October 22nd hastily approaches, Microsoft is slowly but surely dropping all sorts of knowledge on to-be Windows 7 buyers. The latest tidbit about the forthcoming OS revolves around upgrades, with a company spokesperson reportedly confirming that users running an activated version of Windows 7 Release Candidate will not have to "reinstall an older version of Windows before using a Windows 7 upgrade disk." Unfortunately, those who choose this path will see all of their files and such ushered into a folder labeled "Windows.old" when the final version of Win7 is installed, essentially putting a damper on what would've been an otherwise awesome experience. Interestingly, the fun doesn't stop there; if you ever need to reinstall the final version of Win7 from scratch using the upgrade copy you purchased, you'll first need to install (and activate) a copy of XP or Vista, which is different that Vista's somewhat more lax upgrade policies.
