The UAC, which is actually an acronym for User Account Control has recently adapted to some changes, especially in its user interface. The change was done with the intention of reflecting the move for making the entire UAC process less annoying. With the new changes, the UAC is now easier to control and much more user-friendly.
In Windows 7, it includes a slider bar that gives permission to its users for configuring as well as choose what particular level of notification they want. This is necessary if they want to make sure that they are fully protected from any unauthorized malicious access. However, because of the new changes, the Disable or the Turn Off button is now elsewhere.
How can you disable the UAC? Or, at least, is there any way that you can turn off the notification prompt so that you only get them less often? The steps to disabling the UAC in Windows 7 are actually quite the same with disabling the UAC in Windows Vista. You just have to take note of some slight changes in the user interface. Plus, the good thing is that there are actually lots of ways for you to turn of the UAC.

Using Control Panel
If you want to use the Control Panel, you can make use of quite a few methods.
1.    Go to the Start menu, click Control Panel, User Accounts and Family Safety, and, lastly, click User Account.
2.    After that, you need to go to the Start menu again, and reselect Control Panel. But, this time, you need to click System and Security, and then Action Center.
3.    You will find a Flag icon in the notification area, which is a fancy term for the system tray. Once you find it, right click on the icon and then click Open Action Center.
4.    Look for Start Search and type in MsConfig. This will start the System Configuration process. After doing so, go to the Tools tab and select Change UAC Settings. Once changed, click Launch.
5.    Find the User Account Control settings link and click on it.
6.    Slide the slider bar up to the lowest of all values, which is actually towards the direction of the command Never Notify.
7.    If you are now satisfied with the changes you implemented, click on the OK button and the changes will be immediately effective. Now, to start, you need to restart your computer.
Using Registry Editor
Another method for disabling the UAC in Windows 7 is with the use of the RegEdit, or the Registry Editor.
1.    First, you need to run RegEdit and find ways so you can navigate this particular registry key (HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System)
2.    You need to find the REG_DWORD value, which is EnableLUA. Once you find it, you must set the value to 0.
3.    It is optional to suppress the UAC consent prompt log. If you want to do so, then the only thing you need to do is to look for another REG_DWORD value, which, in this case, would be ConsentPromptBehaviorAdmin. Furthermore, you also need to set the value to 0.
4.    When done, you must exit the RegEdit and restart you computer. Doing so will turn off the UAC, just like you wanted.
