When you’re returned to the Virtual PC Console window, select the new vir-

tual machine and click Start. Immediately a black window will appear, and

you’ll see Virtual PC attempt to boot off the network. Since that’s not likely

to work, open the CD menu, select Use Physical Drive D: (or whatever drive

letter is assigned to your DVD drive), and pop in your Windows 7 disc. Or, if

you’re installing off an ISO, select Capture ISO Image and select the .iso file.

When you’re ready, open the Action menu and select Reset to boot off the

disc (or image).

From this point, install Windows 7 as described earlier in this chapter.

Windows XP Mode

One of Vista’s biggest failings was its incompatibility—or rather, its perceived

incompatibility—with a broad range of applications and devices during its

early days. Microsoft was so concerned that the same thing might happen with

Vista’s successor that the Professional, Enterprise, and Ultimate editions of

Windows 7 include a free licensed copy of Windows XP for use with the

Windows Virtual PC software.

But rather than running Windows XP in a window, thereby confining XP

applications to a smaller, isolated desktop, XP Mode applications run along-

side Windows 7 applications. Windows 7 and the virtualized XP share the

same desktop, Start menu, and even file type associations. (XP Mode uses a

Terminal Services session for its hosted applications via the same protocol—

RDP—as the Remote Desktop feature covered in Chapter 7.)

The result is a fully functional, licensed copy of Windows XP running more

or less as a layer on top of Windows 7, not altogether different from the 32-

bit layer on 64-bit Windows. And this means, at least in theory, no compati-

bility problems, and thus no barrier to the inevitable upgrade to Windows 7.

(The big exception here is non-USB hardware; if you don’t have a Windows

7-ready driver for one of your devices, the virtualized XP system won’t be able

to talk to it.)

But what if you have the Home Premium edition of Windows 7? Although

you won’t have access to Windows XP Mode per se, you can install XP in

Windows Virtual PC, provided you own an XP license and have an XP install

disc. Or, if that’s overkill, you can try running that cranky application in

“compatibility mode,” as described in Chapter 6.
