[Wine] How to masquerade as Administrator?

[xyzzy1 at hotpop.com]

Greetings,

Wine 0.9 installation.  I installed Internet Explorer using the manual 
procedure in the applications database.

I then changed the version reporting to Windows 2000 using winecfg and then 
went to http://v4.windowsupdate.microsoft.com which went ok until I got a 
"Must be Administrator".

I notice that there is a stub that is IsNTAdmin that seems to be returning 0.

Is there any way to be administrator on my own box with an installation that 
is under my home directory (~/.wine)? Perhaps some sort of "runas" command?
