What is UAC?

User Account Control (UAC) is a technology introduced with Microsoft’s Windows which aims to improve the security of the OS by limiting application software to standard user privileges until an administrator authorizes an increase in usage rights. In this way, only applications that the user trusts receive rights from him to perform advanced system related functions and other malicious software don’t have the necessary rights to compromise or harm the operating system. In other words, a user account may have administrator privileges assigned to it, but applications that the user runs do not also have those privileges unless they are approved earlier or the user explicitly assigns higher privileges to them.

When is UAC triggered?
UAC is generally triggered in the event of

  • Changes to system settings
  • Installing Applications / Device drivers / Active X controls
  • Changes to Windows Firewall settings
  • Changes to UAC settings
  • Windows Update configuration
  • Adding or removing or changing User accounts
  • Configuring Parental Controls

Why disable UAC?

In addition to enhancing the security, UAC (User Account Control) also can get a little annoying sometimes. Normal users don’t like being prompted for confirmation everytime they try to run a key system process or perform administrative tasks even at the slight risk of decreased security. Also whenever a UAC prompt is triggered, the Windows Aero interface is disabled and the Secure Desktop Mode is activated, which can lead to random crashes in some cases.

How to Disable UAC?

There are many ways to disable UAC, you can do so through MSCONFIG (Windows System Configuration) , GPEDIT (Group Policy Editor), REGEDIT (Registry Editor) or the plain simple way – through Control Panel. We will show you the 2 most easiest ways to do so.
