Today, Windows 7′s hit feature, XP Mode hit RTM. XP Mode is a virtual machine of Windows XP Professional built in into Windows 7 Professional, Ultimate, and Enterprise that simulates the XP enviroment inside, and gives you the ability to run programs installed on the virtual machine in Windows 7 natively. This is ideal for those end-users who have applications incompatible with Windows 7. The VM, available on October 22 as a final release uses hardware virtualization on newer computers to run the XP environment using the full speed of the processor. This also might be great for those accustomed to XP’s looks. In any news, Microsoft announced via Twitter and their blog that XP Mode hit RTM and would launch via Windows Update on 10/22. MSDN or TechNet subscribers can download it right now.
