XP Mode is essentially a virtual PC running within Windows 7.
Windows Virtual PC provides the capability to run multiple Windows environments such as Windows XP Mode from your Windows 7 desktop.To download the Release Candidate of XP Mode, go here:
Windows XP Mode is basically a fully licensed copy of XP buried inside the Windows 7 OS. It will not run on all processors (including some fairly modern ones such as Atom), and is only available on the upper two versions of Windows 7 (Professional and Ultimate). I'm not sure if the release version will or won't require you to download the extra functionality like the RC1 version does. Hopefully it'll be on-disk and an optionally installed component.ReplyDelete
