As of April 8th, 2014 Windows has decided to stop supporting Windows XP. This means that any machine running Windows XP is no longer HIPPA compliant.

Windows XP was released in August of 2001, and can be found on many old computers both in the home and in the workplace. One of the difficulties with upgrading your system to Windows 7 or 8 can be trying to run old proprietary applications. Many hospitals and nursing homes have their own software that they use that is not compatible with Windows 7. This means that you may have to upgrade your software as well as your old Windows machine.
Why is XP not HIPAA Compliant?
As of April of 2014, Windows has stopped giving updates and security patches for Windows XP. This means that information is not completely secure and no future security updates will be available. According to HIPAA you have to have measures in place keeping electronic health information secure from people who are not authorized to access it.

What do you do if your facility is still running a device on Windows XP?
You will want to talk to your vendors and see if your proprietary software is compatible with the upgrade and get an inventory of all the devices that need upgrading. You will also want to see if you should upgrade the software or buy new desktop computers. Windows XP requires less resources and upgrading an old computer to Windows 7 or 8 can make the computer run a lot slower depending on its hardware.
