On my work computer I have Windows 7 Professional. I was creating Administrative Images and testing software installation, and wanted a new blank Windows installation (any version) to test on. I use vmware quite a bit on my home PC, but I didn’t have a XP key or CD handy. Bring on Windows XP Mode.
Follow the 3 Steps outlined on the above website. One of which is a 480MB download of WinXP. (Note: Windows XP Mode is only officially available for Windows 7 Professional and up.) Within a few minutes Windows XP will be running inside Windows Virtual PC. All integration tools will be installed. The XP virtual machine will have Local Disks mounted from the Host Windows 7 computer, and it will have networking all setup.
Looking more into things, I found and enabled “Undo Disks” which was just what I needed. (Browse to : C:\Users\$username\Virtual Machines\Windows XP Mode.vmcx, and right-click and go settings). It’s a little more basic than vmware which lets you take snapshots, but it works.
Apart from testing Administrative installs etc. the possibilities are endless. It could even be used to test website designs in IE6.
The biggest plus with Windows XP Mode was that a fully activated genuine copy of Windows XP was installed within minutes.
I did give it a go installing on a Windows 7 Home Premium version, following this guide. It installed, however it did not activate correctly (after many attempts, even entering a correct XP key) due to Windows 7 Home edition, but it left me with the 30 day trial period, which combined with undo disks, will suffice.
