said by Blackbird:Since when does "soon-to-be-unsupported version of Microsoft Windows" itself constitute a security vulnerability problem (assuming the current support patches are implemented, just as for any Windows version)?
I'd guess that they may have applications that won't work on newer Windows versions, and that the time frame left to convert may be too short.
I know there were even some Windows 2000 in some DHS installations as recently as last year.
It may be DHS, but the people who are 'boots on the ground' still endure government bureaucracy. Budget and approval processes are basically what they were ten years ago, even worse with cuts and 'sequestration'.
