Limited User Access (LUA) Paper
Microsoft have just published my white paper "Applying the Principle of Least Privilege to User Accounts on Windows XP" on TechNet at http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/luawinxp.mspx
This paper got probably the longest and most exhaustive reviews of any document I have
ever written, including reviews by the LUA gods such as Aaron Margosis, and it
was pronounced good. In fact, I see that Aaron's site still has the request for Beta reviewers for this paper.
Windows Vista is going to have limited user access built in from the ground up, and everything will be carried out under a limited user account. If you attempt to carry out a task that requries adminstrator access, a dialog box will prompt you to enter your administrative credentials.
If anyone does have a read of my LUA paper, do drop a comment and tell me what you thought of it.
