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

... one of the drawbacks of the WIndows platform - from an development and engineering point of view - is that it's backwards compatible all the way back to (if I'm not mistaken) Windows 1.0. That's an insane codebase to be dealing with. By bundling an XP VM with Win7, they can- for the first time - take the backwards compatibility crap out of Windows and concentrate on providing a stable OS.
Isn't that essentially what Apple did with the transition from 68000 series chips to PowerPC, from OS 9.x to OS 10, and then again from Power PC to Intel?
I've believed this was a necessity for quite a while.

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".
So does this mean M$ will be extending the fully supported period for XP again, as it will be shipping with W7?

On the whole, I find that I prefer Slashdot posts to twitter ones because I don't get limited to 140 chars before
This would be great if Microsoft included a friendly P2V tool like platespin or vconverter. Then when people buy a new PC, it becomes short work to P2V their old XP system into a VM sitting inside their new system. A lot of people hate to upgrade for fear of losing their old files and settings.
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.
Politics is the art of looking for trouble, finding it everywhere, diagnosing it incorrectly and applying the wrong fix.
Probably the best enterprise marketing decision that MS has made in years...

What good is a rootkit in a VM? It'll be open just as long as the user needs to open some legacy app, won't have access to their file system, except what documents they choose to copy over temporarily and may or may not have internet access.
Running Windows in a VM is actually the ideal solution. Do all your net connected stuff via a secure OS like Linux, then open up a few ports for the VM to run games or whatever.
A fool throws a stone into a well and a thousand sages can not remove it.
Seems more like a way to do what Apple did with OS9 (aka 'classic') on OSX. Hopefully, they used the chance to remove as much back-compatibility cruft as they could, too.
