Create a Power Prompt
Another approach is to keep UAC running but use a special command prompt with elevated privileges when you have a lot of system chores to do. Such a prompt lets you launch applications and issue commands without constantly triggering UAC confirmation prompts.
First, create a shortcut to the command prompt (cmd.exe): Locate the Command Prompt shortcut in Start, All Programs, Accessories, and use the right-mouse button to drag it to a location of your choice. Release the mouse button and choose Copy Here. (This keeps the normal Command Prompt on the Accessories menu unchanged.) Right-click your new shortcut and choose Properties. On the Shortcut tab, click Advanced. Check Run as administrator, and click OK.
Because this prompt can launch applications and perform other functions without any UAC prompts, it's a good idea to give it special colors to remind you of the risks involved and to help you avoid mistaking it for an ordinary command prompt. Click the Colors tab and use the controls there to set the colors for 'Screen text', 'Screen background', and other items, as desired (see the image below). Click OK. The changes may affect your default command prompt window as well; if so, you can change those settings back to their default values the next time you open that prompt, and the problem should not return.
Use special screen-text and screen-background colors for your power prompt to distinguish it from a command window with normal privileges.
The next you need to do system-related chores, launch your special power prompt. You'll still have to provide one UAC confirmation when you first open the power prompt. But tasks that you perform from within this prompt--such as creating or renaming folders on the Start menu, launching disk utilities, and running installers--will be UAC prompt-free.
