UAC or User Account Control is a security message that appears whenever you try to access a program or software and ask for your consent before the program or software can make any changes to your computer. The goal is to avoid any unexpected activity on your Windows system.
So basically you have to click Yup to proceed e No if you do not want. The UAC settings are set by default to the recommended level which forces the user to continue only after their consent. However, when you disable UAC by changing the setting to Never notify, you may see an error message "You need to restart your computer to disable UAC".
Now, if you are the only user on your machine and have UAC disabled, there is nothing you need to worry about. Reboot the system and the UAC will shut down completely.
