Determining OS version from the Evo stack trace

Evolution software uses a third-party component for error handling and reporting, and this includes a detailed stack trace on error. An example snippet

...
date/time         : 2015-09-26, 13:44:04, 532ms
computer name     : EVO1
user name         : SYSTEM 
operating system  : Windows NT New Service Pack 2 build 6002
system language   : English
...

Unfortunately, the "operating system" reporting hasn't been updated it some time to reflect the common name, so all versions beyond Server 2003 have a generic string that includes the build number. It's this build number that allows us to determine the operating system:

Build number	Operating System
2600	Windows XP
3790	Server 2003 (all editions, including R2)
6000	Windows Vista
6001	Windows Vista SP1
6002	Server 2008 and some Vista
7600	Windows 7
7601	Windows 7 or Server 2008 R2
9200	Windows 8.1, Server 2012 and beyond

It's not always possible to tell from the build number whether it's the desktop OS or the corresponding server OS, but you ought to be able to figure that out from context.

• Windows Vista ≈ Server 2008
• Windows 7 ≈ Server 2008 R2
• Windows 8 ≈ Server 2012
• Windows 8.1 ≈ Server 2012 R2
• Windows 10 ≈ Server 2016

Note that Service Packs are just cumulative sets of updates not really impacting the version, but R2 is considered a different version of the operating system.

We believe that all future OS versions will continue to report #9200 to applications unless that app has been built specially for the newer OS: this is a kind of workaround to application-compatibility issues.

We'll update this table as we learn more.
