Changing the Settings
By default, the cursor should be at the second-highest option (which is bolded as the recommended setting). If you wish Windows to give you more notifications when changes are being made to your computer, you can move the cursor to the highest possible setting. The highest setting is what Windows Vista had equipped with it. If you’re a former Vista user who preferred having the high UAC alerts, this setting may apply to you.
Moving the cursor to the second-lowest setting will still give you the same amount of warnings as on the default setting, but your desktop just will not be dimmed. It’s not a bad choice if you don’t mind the current UAC setting, but don’t want to have to deal with the drama of having your screen dim every time a message prompts you.
To disable UAC entirely, move the slider to the option at the very bottom. Windows of course does not recommend that you choose this setting, as this can leave your computer open for a potential attack. However, the majority of programs most users have on their computer were downloaded from the internet. Every time you try to run a program you have just downloaded, you will be prompted by default from that web browser whether or not you want to run the program. If you have that security, you may not need UAC messages.
Once you’ve chosen the option you want, click OK. Windows will then tell you that the settings will take place once you restart your computer.
