If you're a reader of this blog, I'm going to take a low-risk gamble and assert that you probably consider yourself a power user. You pride yourself in the responsibility of having full and absolute control over your machine environment and anything that comes between that perfect human-machine symbiosis is to be spurned. If only there were a way to turn User Account Control off on a Windows Vista machine, you'd upgrade immediately. Well, dear reader, I'm here to help.
Firstly, it's worth a brief digression into the benefits of this feature. Running as admin is a bad thing, as most of us know. Aaron Margosis has blogged extensively on this issue, and I won't rehash it here. But for reasons of compatibility, running as a standard user can still be a somewhat painful proposition. Windows Vista attempts to give you the benefits of both worlds by allowing administrators to execute most processes in the context of a standard user and only elevating the privileges on their user token by consent, in addition to allowing standard user accounts to perform administrative tasks by selectively elevating a process to use administrator-level credentials.
In general, UAC has turned out pretty well. It was pretty intrusive in early builds, prompting often and sometimes capturing focus at the wrong time. For the vast majority of users, UAC will offer a valuable level of security protection that will protect against malware: it simply won't have the rights to perform invasive actions like installing device drivers or services. Once a system is configured, you'll rarely see UAC prompts unless you're an inveterate settings tweaker. Incidentally, you can find out a great deal more about how UAC works, what you need to do to your own applications so that they co-operate well with UAC, and the rationale for its design at the official UAC blog.
It is possible to switch UAC off. I really don't recommend it - if you like full control over your machine, surely you want to know when something is attempting to perform an administrative-level action? Nevertheless, I'd prefer to have you run Windows Vista without UAC than having you run a different operating system.
There are two ways to disable UAC. The easy solution is through Control Panel. Type "UAC" into the search bar at the top of the screen and you'll see this task presented:
This approach is pretty brute-force, though. It just switches the whole thing off. There's a more subtle configuration choice that gives you some of the benefits of UAC without any of the prompting. You'll need to edit the local security policy to control this, as follows:
Perhaps the best choice to select is to change the setting: User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Modefrom Prompt for consent to Elevate without prompting.
What does this do? Despite the warning from the Windows Security Center, UAC isn't actually switched off. It's still there, and all your processes will still run as a standard user. To prove this, open a command prompt and try to save a file to the c:\ directory. You'll get an access denied error message. However, when a process is marked for elevation, instead of getting the secure desktop elevation prompt, the request will be silently approved. To show this in action, right click on a command prompt shortcut and choose "Run as Administrator". You'll see the command prompt open without elevation, but the window title will show that you're running with full administrative privileges.
Using this approach is better than nothing, but it's a bit like relying on everyone else having a vaccination against measles to protect yourself from infection. Read the explanations on the second page of the property sheet for each policy setting before tinkering, and be careful!
There's also a setting in Local Security Policy to not use "Secure Desktop" for UAC. This will diable the "lock and dim" behavior but not the UAC prompt.
The only downside of this is that malware (in another process) could possibly interact with the UAC box and click "Yes" for you.
Help how do I config UAC so it auto-elevates without prompt ONLY for command prompt shortcut in start menu and nothing else.. There must be a way..
User Account Control is, as I mentioned in secret #4 , an important part of the security protection that
If there's one thing that puts me off an application, it's when it unnecessarily inserts itself into
You should be disabling UAC like this:-
go to security policy and disable "run all administrators in admin approval mode"
Changing "Behavior of administrators in admin approval mode" doesn't really turn off disable UAC services underneath.

can i elevate myself from the commandprompt? (possible getting a prompt for verification if it is not set to elevate silently?
Mike Peter Reed - "I was lost to OS X in 2003. It only prompts me for the admin password when I am administering something, not when I want to do something. I can install all the programs I want in my home folder and I have full access over them. Windows Vista is a kludge but don't let that stop you having fun administering it rather than doing anything constructive like personal computing. "
Construstive things like going around to other peoples blogs and telling them they are stupid for using PC's....good one there Mike!

Yes there is always a Mac fanboy on every forum or blog because thats all Macs are really good for, surfing the web...might as well use a mobile phone probably has as richer applications!
