Partner Briefing notes

Hi all. I apologize for the lack of postings this past 4 weeks. There's been a lot going on!

To whet your appetites, I'm posting the text from my brief talk at the Mobile PC Partner Briefing, which was held on MS Campus Feb 1st and 2nd.
To those I met, I'm glad I met you and hope we can meet again! To those I didn't get to meet, I hope to meet you someday!

What’s changed in Vista vs XPSP2

   New input modes

   Device form factors are more varied

   User account control

   64-bit compatibility required for (Windows) logo

Input modes

   Mouse+kb - can’t assume people will have this anymore (slates)






Devices are more varied now

   Fujitsu p1510d (1024x600)

   Motion LS800 (800x600)

   Toshiba Tecra M4 (1400x1050)

   Intel GMA (Graphics Media Accelerator) limitations (1024x768)

User Account Control (UAC) Aka Least-privileged User Account (LUA) aka User Account Protection (UAP)

   What is it

      All interactive administrator-group accounts run as Standard User but have “elevation potential”

      Applications have to be marked to require administrative privileges

         -One-time elevation

         -Always run elevated

   ConsentUI must be handled interactively

   Most common effect likely to be setup/uninstall (file system access)

   UI Privilege Isolation (UIPI) enables Windows to block applications at lower privilege levels from sending messages or hooking threads against processes with higher privilege; protects vs. “shatter” attack

Why is it

   UAC prevents attacks by malware, root kits, spyware and viruses by limiting admin-level access to authorized processes

How do I deal with it

   Can no longer assume user has admin privileges by default

   Whitepaper available simultaneously with Vista Beta 2
