Surun beats all Sudo like applications in Windows

If you ever tried to work in Windows NT systems as a limited user you surely have encountered wondrous things like having no permission to change the Windows clock and especially when installing applications. Working as a limited user on the other hand increases system security because malicious code will run with the same privileges which as the name implies are rather limited.

An owner of a computer surely wants to install software on it even if he is running as a limited user. This is where the problem starts. The Run As command can be used to run applications as a different user. The major problem is that you have to provide the username and password for that user to be able to run the selected application. This data can be easily logged by a keylogger.

Surun uses its own Windows service that adds the user to the group of administrators during program start and removes him automatically from that group again. The user, not the administrator, will be asked on a secure desktop that only services may access if he wants to run the program and if he confirms that the application will be started. Programs are started with a right-click and the selection of Run as Administrator.

Surun comes with lots of settings and a huge configuration. Each application that was once started with Surun can be added to a list of applications that are started without the prompt from then on.

    I just have been working with Surun 1.2 for a while running XP Professional. It is surprising how well designed this program is. I found it much easier to use than I thought and if you understand the theory of using a limited user account you see how much simpler life can be – I wonder if this is better than Vista’s thing (I’ve only read about Vista’s system). I especially like how the little icon in your tray turns red and a clear popup tells you a program is runing with admin rights. Since the author is German it is great to find the program written in very clear English.

    I really like the layout of this program. Perhaps it is too new to be considered “safe” for critical uses but I have been surprised at how little this functionality impacts performance (I even tried it on a P3 800 mhz machine with XP pro – no noticeable performance slowdown.) So far so good.

    less than 2000 to go in less than eight months, that should be doable ;)
