May 26, 2012, 7:50 AM — SIUC asked the Windows forum about running software intended for Windows XP in Windows 7.
For the most part, it should just work. I've rarely run into programs that run fine in XP but have trouble in Windows 7.
But if you've run into one of those rare programs, try running it in XP Compatibility Mode:
Right click the .exe file or the shortcut and select Properties. Click the Compatibility tab. Check Run this program in compatibility mode for and select an appropriate option.
If this doesn't work, there's another work-around: XP Mode. (And yes, I know it's silly that the two solutions are called XP Compatibility Mode and XP Mode.) Unfortunately, this option is only available for Windows 7 Business and Ultimate editions.
You'll need to download and install Windows XP Mode and Windows Virtual PC (be patient; it's a big download).
Once you're finished, you'll be able to actually run XP inside a virtual machine in Windows 7. It's not as smooth as simply running the programs in Windows 7--you're in an entirely different environment. Even the hard drive that XP boots from and runs off of is a virtual one.
But you won't be entirely cut-off from Windows 7. You will be able to access the real hard drive from within XP, and both versions of Windows will share the same clipboard.
