To turn it off just move the slider all the way to the bottom to “Never notify”. UAC is controlled by a slider that controls its level of intrusiveness, as shown in the image below. In Windows 8.1, search the Control Panel for UAC. However, if you find it too annoying to put up with, just enter UAC in the Search box in Windows 7 and Windows 10 and click on the link provided above the box to bring up the User Account Control Settings window. Note that it is not advisable to disable UAC, because it is a key security feature against malware infections and hacking attempts.
Unless it is disabled, you can’t even set Windows to run msconfig to start up in Safe Mode from within Windows without granting UAC permission. It requires the user’s permission to install and run software and tools. User Account Control (UAC) is the feature that most people who have used Windows Vista/7/8.1/10 are familiar with.
