According to a user by the nickname, "seveninsider" on AeroXP, build 6780 has gone out to the very, very select number of TAP customers. Usually designated for large companies and colleges, the TAP program is the mother of trust between Microsoft and whoever they accept. Members of a TAP receive very early builds of whichever program they're accepted for. (There are various TAPs... Windows, Office, etc.) Anyway, though it's very, very little to go by at the moment, "seveninsider" left a very miniscule teaser in addition to a couple of tidbits of information:
"...it has some nice new features that are not yet publicly known and major improvements to some old friends (WordPad, Paint, Calculator)... They also seem to have worked on the performance-side quite a bit... (I am running it inside Virtual PC 2007). This might also be the build that gets distributed at PDC an WinHec in October, who knows...."
With PDC right around the corner, it very well could be. With Microsoft undoubtedly thinking about the PDC build, it would make sense to gather all the information they could from TAP testers prior to compiling the PDC build, reports Stephen.
