Windows XP was first released in October 2001, making the software now over 12 years old. Microsoft announced in April 2012 they will be ending support for Windows XP in April 2014, this means they won't be releasing any updates to fix security problems or other bugs. We haven't taken this decision lightly, however, given the security risks involved with unsupported versions of Windows and the sensitivity of data that myPractice holds we too will no longer be able to support myPractice running on Windows XP from this time onwards.
An unsupported version of Windows will no longer receive software updates from Windows Update. These include security updates that can help protect your PC from harmful viruses, spyware, and other malicious software, which can steal your personal information. Windows Update also installs the latest software updates to improve the reliability of Windows—new drivers for your hardware and more. More information is available here in regards to upgrade options for Windows: http://windows.microsoft.com/en-au/windows/end-support-help
Don't wish to upgrade? Windows will still work however you will be at a higher risk to viruses and other security problems. The current version of myPractice will continue to work on XP as will Version 5 when it is released early in 2014 however any updates to myPractice after April 2014 won't be guaranteed to run on XP and we will no longer test the software in an XP environment after this time. This is not to say you can't continue to use the current version of myPractice in an XP environment at your own risk.
Once an Operating System is no longer supported from Microsoft you will find that many other Software Vendors will follow suit given that we need Windows to be up to date for software to run correctly. This article sums up the case quite well as to why you should consider making the move away from Windows XP: http://www.ltnow.com/windows-xp-end-of-life/
We encourage all of our clients to take this time over the coming months to make the change away from Windows XP to either Windows 7 or Windows 8.
