Windows 7 To Include "Windows XP Mode"

Z80xxc! writes "Paul Thurrott's WinSuperSite reports that Windows 7 will include a built-in virtual machine with a fully licensed copy of Windows XP Professional SP3. The VM runs in a modified version of Virtual PC, and applications running in the VM can interact directly with the host operating system as if they were running on the Windows 7 installation itself. While details are scarce for now, it looks as if this feature will only be available as a (free) addon for Professional, Enterprise and Ultimate editions of Windows 7. Also, a processor supporting hardware virtualization will be required, indicating that this is perhaps aimed more at power users and corporate users, rather than consumers. Microsoft confirmed the feature last night."

Wait a second

if it will run XP mode software, wouldn't that mean XP style viruses now have a key right into the system?

Won't solve a whole lot

[SilentChris]

Unfortunately, while this is a long overdue solution that other companies have used fine before, but it's going to prove problematic for Microsoft. Things that won't work (and Joe User will try to do anyway):

1.) Install their XP-compatible Antivirus program. "It said on the Windows 7 box that I could run old programs!"
2.) Install a printer which works on XP only. "The printer box said it works on Windows. Why can I only print from some programs (the older ones seem to work)?"
3.) Play an old game at reasonable speed. "I installed Super Hardware Killer Shooter for Windows XP and the 3D is running really slow!"

Virtualization is a great thing. I use it work all the time and love it. The public doesn't quite "get it" yet. They're going to see some things work, some things not and wonder why the hell that is. It happened when Apple moved to OS X, but the user base was much smaller so the complaints were less.

Until someone creates a hypervisor which is presented in a completely transparent way to the OS, in that things difficult to virtualize (e.g. video card hardware) run at normal speeds, it's just going to appear to the user "every time I run an old program, either it's too slow or it doesn't work".

Requested by the Military

The U.S. Military is heavily invested in several applications that have been tested at Microsoft. (Military members do have offices in Redmond for this purpose.) Windows 7 was shown to have some issues. The USN scrapped plans to move to Vista, planned for this quarter, and decided to wait for Windows 7, but needed XP compatibility. The VM compromise was brewed up.
