Enhanced Protected Mode is a security feature that was introduced in Windows 8. By default, this feature is turned off in Internet Explorer on the Windows 8.1 desktop.
When this feature is enabled, add-ons such as toolbars, browser helper objects (BHOs), and extensions are loaded only if they are compatible with Enhanced Protected Mode. If you have to load an incompatible add-on, you can disable Enhanced Protected Mode for the desktop browser. This action lets incompatible add-ons load, but it may increase the risk of having malware or other potentially harmful software installed on your computer.
To enable Internet Explorer to protect your computer and personal data, Enhanced Protected Mode isolates untrusted web content in a restricted environment that's known as an AppContainer. This process limits how much access malware, spyware, or other potentially harmful code has to your system.
Add-ons that are incompatible with Enhanced Protected Mode are not loaded when Enhanced Protected Mode is enabled.
If you have an incompatible add-on installed, you can choose to disable Enhanced Protected Mode for the desktop browser. To do this, you can follow the steps in the "Workaround" section. However, because Enhanced Protected Mode provides protection from malware, you may want to first contact your add-on vendor to see whether a compatible version of the add-on is available.
This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
To disable Enhanced Protected Mode, follow these steps:
- Start Internet Explorer for the desktop.
- Tap or click Tools, and then tap or click Internet options.
- On the Advanced tab, click to clear the Enable Enhanced Protected Mode check box under Security.
- Tap or click OK.
