When User Account Control (UAC) was introduced in Vista, users found it annoying. It’s less intrusive in Windows 7, but power users typically turn it off. Here’s how to turn off UAC in Windows 8 Developer Preview.
From the Metro UI click on Control Panel.
Next, scroll down the left panel and click More Settings.
The Control Panel window displays. Change View by to Large icons.
Scroll down and click User Accounts.
Next, click Change User Account Control Settings.
Now set the slider all the way to Never Notify. Click OK.
Then click Yes when the UAC verification message comes up. Then close out of Control Panel.
If you’re installing several programs in on sitting, you can turn off UAC to avoid having it constantly popping up. Then remember to turn it back on to get the extra security protection it provides.
If you’re new to computing, I recommend not turning it off.
