The name change to UAC likely happened when it forked off into two separate things, as LUA (Limited User Account) is also a Microsoft term as seen by the user control panel in 2000/XP. Least-privilidged User Account is another name for the LUA acronym that most of the industry uses and as you said this is likely why the UAC name came around. Because they are separate, you can run Vista as a LUA, without requiring UAC to be on.

With all the codenames and internal only names we use here, I can see how such things could easily be confused inside a larger company. Would be interesting to see how many of the Windows developers still call it Longhorn after hearing that name for many more years over Vista.


On the topic of UAC, I just brought a new vista box online here at work, and instead of being annoyed the first second a UAC box appears, I'm trying to live with it. One problem with that though, it doesn't play nice with Synergy. I have turned off the "Use Secure Desktop for elevation requests", and Synergy still can't click on the popups, I have to use a hardwired mouse to do it. Any way around this, possibly with another remote keyboard/mouse solution?
