The UAC (User Account Control) feature is a handy feature in Windows that asks you if you are okay with a change you are going to make. But several users find this pretty annoying.
If you want to disable and get rid of this feature in Windows 8, then here is how. It’s just a matter of steps.

1. Type msconfig in Run or in the Metro screen and a window should open up.
2. Go for the Tools tab.
3. Choose on the Change UAC Settings option.
4. Now go for the Launch option.
5. The lowest level shown is the one you are looking for. Choose it to never notify and apply the changes to disable UAC.
