Vista Build 5728
Vista 5728 installed on the main PC (did an upgrade over 5600). Not noticed any real differences which is to be expected I suppose. Will be interesting interesting if I can get Office 2007 working in this beta 
.
Weridly though the performance thingy went up from 4.7 to 5.0 which is good I suppose. Just need to get the last few bits of software working like printers, VNC Manager, WinRAR, Nero, FlashFXP and Adobe CS2. Once they’re running on it I’ll be a happy chap.
This new build of Vista installed perfectly on Parallels on the macBook Pro running OS X 10.4.7. Did an in place upgrade, took about an hour and a half and is there working perfectly as before . Still no point in using it in Parallels over XP has the software I like doesn’t work perfectly in it.
