"Server" operating systems should not be used as a Desktop operating systems - they are not designed for this function. The applications are not tested nor certified when using any Windows "Server" version as a desktop, personal computing operating system. Server versions are listed here for clients using Remote Desktop Services to 'publish' the products through virtual desktops. Server operating systems may display some parts of a program's interface a little different (menus, toolbars, etc.) which does not affect the overall usability or functionality of the program.
On Center Software supports our software on versions of Windows currently under "Mainstream Support" with Microsoft only. Once a version of Windows is 'retired' by Microsoft, products that were supported up to that operating system only are considered "deprecated" and OCS no longer provides technical support for them.
