Use Windows XP In Virtual Environment
Windows XP can run in a virtual environment on a Windows 7 PC, enabling the client to get the added benefit of using a more modern operating system. This may be an option for some firms that have custom software that won't run properly on Windows 7 or above.
IT administrators also can add whitelisting software to prevent code from executing on Windows XP systems, say some experts. Modern whitelisting sold by Bit9 and other vendors provides active monitoring over applications and systems, and can support physical or virtual workstations and servers. End users will be impacted by authorizing only mission-critical applications on XP systems, but the environment will be locked down to the point where executing code will be more difficult to carry out.
