    TrustedInstaller User?

    I ran icacls on c:\windows and noticed a account called NT
    Service\TrustedInstaller that has full access to the directory. But I cannot
    find this account in the list of users on the my Vista Machine.
    Research shows that this is the account used by Vista installation service
    for installing applications. But Task Manager does not show any service or
    process running under that account.

    Can someone demistify where this account resides and which service uses
    this? Can I create additional directories and only allow this account to
    create/write files to it?

    TrustedInstaller _is_ the Installer service. It is actually a Service SID
    representing that service. The fact that it is the only thing that has write
    permission to system binaries means that it is the only thing that can update
    them (without jumping through hoops).

    Yes, you can make that account the only thing that has permissions. It is
    treated as any other account for access checking purposes.
