I've been trying the public Beta occasionally since it was issued.
After removing the Fisher-Price look and feel elements, tweaking the pagefile size and disabling unnecessary (for my purposes) services, I've managed to get the Vista Beta reasonably useable on my 5-year-old Dell laptop (1Ghz PIII/768/16Mb MobilityRadeon/60Gb 7,200) and C Dock II (inc. 128Mb nVidia 5200 PCI and USB2/1394). Just one hardware item it didn't install, in the dock - a SCSI controller - whatever it is, I don't use it anyway!
I've installed the Trend beta/freebie package, installed Firefox 2 Beta 1, Agent Ransack and a few preventative anti-malware measures; disabled Windows Defender and firewall. I can't seem to be able to disarm the security alerts though. (I'd like to get rid of the battery/mains indicator in the taskbar when mains-powered, too.)
I have to connect to my wireless network manually - no big deal, really.
It runs fine for basic tasks on the 'net, I've even got it playing FarCry on the lowest setting - it's not bad, but it plays a couple of levels of graphics higher on XP.
Currently starts up (rather slowly) using @35 processes, @400Mb of pagefile and leaving @ 320Mb of RAM free.
I'd like to be able to use Hardware Profiles like XP to create an offline/games/streamlined mode, can't see how to yet - maybe I'll have to create a new User and see if I can do it that way.
I've lost the ability to use both inbuilt and dock graphics cards together - I'd like to get that working.
What happened to the two-paned Explorer? I can't see an option to enable it - any alternatives that work that way?
No surprise that my system had a Performance Rating of 1 - until I disabled processes needed to test it
Just noticed that there's a bug in the formatting in Notepad as I put this together, I hope it's just something I've done ...
