Re: Remove permissions to install software from Power Users group



That's still not good enough. There are some exploits (I'll leave the research up to you, heh) that allow power users to elevate to administrators. That's why we've removed power users from Windows Vista.

Instead, demote your users to standard user. Then, for troublesome applications, profile them using Aaron Margosis's LUA BugLight tool. This will allow you to relax permissions on particular registry keys and files so that these apps will run under standard user accounts.

Hi Shenan,
Thanks for the speedy reply.
I too am a firm believer in the "least priveledges required" rule -
unfortunately we run so many different applications, it would take me many
months to identify the user requirements for each application. The Power
Users group membership ,without the ability to install software, would be a
lot more secure than the position we are in currently - i.e. all users are
local Administrators.
Thanks,
Kieron

When dealing with security - give least privs first and GRANT what is
necessary beyond that. Do not try to work in the opposite direction. You
will end up giving to many rights and possibly - not even know you did it
until things go wrong.

If they have software that is not working when they are simply 'users' on
the workstation, you should try and discover why (likely file/folder
permissions to the program folders and/or to the All Users profile
directory - MAYBE permissions to a given registry key...) and fix that
instead of continuing to grant the users more rights than they should have.
