User account control (UAC) is an important part of Windows that helps to prevent potentially harmful programs from making changes to your computer by notifying you before changes are made to your PC that require administrator permissions.
We don't recommend that you alter or disable this feature but if you would like to alter these settings you can do so by following this guide.
How to change the Windows 8 user account control settings
Logon with a user account that has administrative permissions.
From the Windows start menu, type "Control".
Within the search results on the left of the screen click "Control Panel".
If you are using category view click on "User Accounts and Family Safety". If you are using Large Icon or Small Icon view you can skip this step.
Click on "User Accounts" and then "Change User Account Control settings". If you are prompted by the User Access Control click "Yes" to continue.
On the User Account Control settings screen you can move the slider bar up and down to set the security level of UAC.
As you move the slider up and down you will see that the description to right change. These explain what each of the different UAC security levels mean.
Once you have changed the security level click "OK". If prompted by User Account Control, click "Yes" to continue and apply your changes.
important note: If you set UAC to "Always notify me", then you will not be able to use the refresh or reset features of Windows 8 as they require UAC to be set to the default or lower level to work.
