First I’m going to tell you how to stop Windows 8 from asking for permission to do stuff all the time. Then I’m going to explain why you shouldn’t stop Windows 8 from asking for permission for stuff.
To stop Windows 8 from asking for permission all the time:
Click the Windows button
Drag the slider right to the bottom of the scale
Click Yes and enter your administrator credentials if required
Restart Windows 8
This will stop stop Windows 8 from asking for permission to do things all the time, how here’s why you shouldn’t do what I’ve just told you how to do :p
Windows 8 has a feature called UAC, which stands for User Account Control. Whenever something that can harm the computer (by changing the settings) wants to run, you have to specifically tell Windows 8 that it has permission. This stops viruses from doing administrative things and delivering their damaging payloads without the user noticing. It’s as simple as that.
Right now, you’re probably thinking that you can stop Windows 8 from asking for permission and your antivirus software will take care of the viruses, right? Wrong! Antivirus software can typically only stop viruses that have been around for a few days. This is because the viruses have to be noticed before your antivirus software provider can then get an example of the virus, study it and release the fix. Windows 8 gives you this extra level of virus protection by stopping many viruses from damaging your computer, stealing your bank details or whatever the virus is designed to do before the antivirus company even knows that the virus exists!
Of course this is a bit of a nuisance, so people naturally want to stop the constant asking for permission and that’s entirely up to you. But it’s not recommended, which is why Windows 8 asks for permission by default.
