It is a native 32-bit Win32 application. Sandra is an acronym and has no connection whatsoever express or implied with anything or anyone, living or deceased in the past, present or future.
Any resemblance is purely coincidental.
BTW, don't search for the name Sandra on a WWW search engine. You'll get at least half a million hits and none will reference this page. Search for SiSoftware Sandra . You still get information on the 16-bit subsystem. Enhanced, SSE, SSE2 and other CPU information like cache, speed, etc.
