    Great read. The bottom line is you're more vulnerable using an admin account + UAC (split token) than a standard user account. It's also interesting that he says there are similar vulnerabilities using the credentials of a different admin account for process elevation on a SUA desktop, and instead recommends fast user switching to create a separate session with an admin account. I don't know how well that would work ( ? )

    Oh and by the way I thought I would refresh everybody's memory as to who Mark Russinovich is. Sysinternals,( creator of all those cools programs you all use, Process Explorer, Autoruns, ect.) Rootkitrevealer, Detected the Sony Rootkit, last heard like Ep_xoff works for Microsoft. Over.
    I run as ADMIN and have UAC set to max and it doesn't bother me at all and I install and run a lot of crap.:D

    It's not realistic, it would annoy people and that's also the cool thing about Windows, at least it gives you the choice.

    That would mean educating inexperienced users about the need for/difference between a Standard User and an Administrator account - not going to happen.

    In my limited experience with Linux, I've never had to switch between Admin and SUA accounts. I have just been asked to enter my password when installing software.

    yes the sudo command (similar to UAC prompt) but the two accounts in linux are clearly separated unlike in windows. im not Linux expert, i just know how to use it.

    Okay, so in Linux, you get the same amount of security without having to switch between accounts, as you do in Windows by switching between Admin and SUA.

    I've just created SU accounts on my two Win 10 machines, and everything works perfectly. I tried SUA with Vista and XP in the past, but there were always problems with the functionality of some programs. With Win 10 it is really flawless. This is a very informative thread, thanks!

    to be simple, normally when you install Linux, it creates 2 distinct accounts: the root (admin) account and the user (default) account in which you will be logged in right away (opposed to windows ).

    in Linux, you will normally never need to switch to root account, because the standard user account give you the sudo command, so you can have root "rights" in your standard account in exchange of the password.
    MS just copied Linux with SUA and UAC .

    in Windows SUA is just the admin account stripped from some privileges resulting into a limited account.
