3CX & Microsoft Windows XP Support

July 17th, 2012



Since the announcement that 3cx has released the new version (version 11) of the 3CX Phone System, and 3CX Myphone for Windows, IOS and Android, many of our existing customers have been asking Century IT Services why the new version of 3CX, version 11 that offers so many improvements as a phone system, now isn’t supported on Microsoft Windows XP.


This blog entry will hopefully answer that question explain the direction that software companies like 3CX are going in.


Many software companies create their software using a Microsoft development system called .net. This framework gives developers a stable platform to access all the different flavours of Microsoft Windows with ease, so that they can create the software code once and it will run on any version of Microsoft Windows. The disadvantage with this framework that when Microsoft decide to drop support of a certain version of Microsoft Windows from this system the software developers have to drop it from new versions of their software too. And that is really where we are with 3CX and Microsoft Windows XP.

If you stand back and look at Microsoft Windows XP the answer really is clear. Windows XP is now a very old Operating System that started off in 2001 and Microsoft have been trying to retire since the fated Windows Vista was released. Microsoft have extended support for XP but now that Windows 8 is looming the time has come to move on.


Support for Microsoft Windows XP has now stopped and it is now on ‘extended support’ and even this will stop in 2014 which isn’t really that far away. After the extended support period has ended no new security updates will be released. This will make Windows XP vulnerable to attack from new viruses and malware.


The other major reason for dropping Microsoft Windows XP is that 3CX are now developing their software to run using 64bit native code. The advantage of developing 64bit software is that the 3CX will run more efficiently on newer hardware. This means that the same hardware will be able to reliably handle more extensions, lines and conference calls etc. when running the 64bit version of the 3CX Phone System software.
