Planning To Run Office 2013 On Your Windows XP System? Think Again
If you are running WinXP or Vista and you're willing to upgrade, there's some good news: Microsoft announced earlier this month that it wil make the Windows 8 upgrade $39.99 when Windows 8 is officially released. The Windows 8 upgrade (not Office) supports operating systems as old as Windows XP. You'll just need to find a friend with a newer OS if you want to check out the preview of Office.
Microsoft's Office Customer Preview FAQ has some worthwhile information for anyone planning to take Office for a spin. A couple things to keep in mind: you can install the preview alongside your current Office without affecting it, and you'll need to be at Release Preview or higher if you are testing Windows 8.
