As others said, you can use a VM for WinXP (both VMWare and VirtualBox are free and run well on Win7) or Win7 XP mode.=20 You can also get yourself a cheap old computer where you install WinXP and run it headless, controlled with e.g. VNC. (Or, if you have a spare monitor to go with it, use Synergy to use your keyboard and mouse to control it. Or use MaxiVista and get an optionally extended desktop for your main system.) Another option may be to disable Win7 UAC. This may make a few things a bit simpler -- but you lose a helpful bit of security. It is not so difficult to create a shortcut that runs an application with elevated privileges, for the apps that need it.
