Microsoft Agent 2.0 is the latest version and current release of Microsoft Agent. It is an upgrade to Microsoft Agent 1.5, its predecessor. It featured many changes and also revamped the Microsoft Agent API to the point where most code made for Microsoft Agent 1.5 specifically would not run properly or not run at all if Microsoft Agent 2.0 is installed over Microsoft Agent 1.5. This is also the first public release of Microsoft Agent to install itself in the WINDOWS/WINNT directory instead of the Program Files/Program Files (x86) directory. It is also the first public release to use "CHARS" as the name of the folder ACS files go in, as Microsoft Agent 1.5 used a folder named "Characters".
Development
The first available build of Microsoft Agent 2.0 is in Windows 2000 build 1723. In Windows 2000 build 1701, Microsoft Agent 1.7 was included, which means Microsoft may have skipped 1.8 and 1.9 or they were in the in-between and undiscovered builds. The version of Microsoft Agent 2.0 inside of Windows 2000 Build 1723 is version 2.0.1114. This build has a mention of Microsoft Agent 1.6 inside of it and also has the taskbar icon that comes up when AgentSvr.exe is running removed.
Trivia
- Microsoft Agent 2.0 is the default Microsoft Agent installed on old Windows versions.
- The only known exception to this is Microsoft Agent 1.7, which was in a beta release of Windows 2000.
