Problems after installing Internet Explorer 11
After you install Internet Explorer 11 in your organization, you might run into the following issues. By following these suggestions, you should be able to fix them.
Internet Explorer is in an unusable state
If IE11 gets into an unusable state on an employee's computer, you can use the Reset Internet Explorer Settings (RIES) feature to restore the default settings for many of the browser features, including:
ActiveX® controls (resets to the opt-in state, unless they're pre-approved)
Branding settings created with IEAK 11
RIES does not:
Clear the Favorites list, RSS feeds, or Web slices.
Reset connection or proxy settings.
Affect the applied Administrative Template Group Policy settings.
RIES turns off all custom toolbars, browser extensions, and customizations installed with IE11. If you change your mind, you can turn each of the customizations back on through the Manage Add-ons dialog box. For more information about resetting IE settings, see How to Reset Internet Explorer Settings.
IE is crashing or seems slow
If you notice that CPU usage is running higher than normal, or that IE is frequently crashing or slowing down, you should check your browser add-ons and video card. By default, IE11 uses graphics processing unit (GPU) rendering mode. However, some outdated video cards and video drivers don't support GPU hardware acceleration. If IE11 determines that your current video card or video driver doesn't support GPU hardware acceleration, it'll use Software Rendering mode.
To check your browser add-ons
Start IE11 in No Add-ons mode by running the Run command from the Start menu, and then typing
iexplore.exe -extoffinto the box.
Check if IE still crashes.
If the browser doesn't crash, open Internet Explorer for the desktop, click the Tools menu, and click Manage Add-ons.
Click Toolbars and Extensions, click each toolbar or extension, clicking Disable to turn off all of the browser extensions and toolbars.
Restart IE11. Go back to the Manage Add-Ons window and turn on each item, one-by-one.
After you turn each item back on, see if IE crashes or slows down. Doing it this way will help you identify the add-on that's causing IE to crash. After you've figured out which add-on was causing the problem, turn it off until you have an update from the manufacturer.
To check for Software Rendering mode
Open Internet Explorer for the desktop, click the Tools menu, and then click Internet Options.
On the Advanced tab, go to the Accelerated graphics section, and then turn on Software Rendering mode by choosing the Use software rendering instead of GPU rendering box.
If the Use software rendering instead of GPU rendering option is greyed out, it means that your current video card or video driver doesn't support GPU hardware acceleration. For more information, see Windows 10 Support.
Adaptive streaming and DRM playback don’t work with Windows Server 2012 R2
IE11 in Windows Server 2012 R2 doesn’t include media features like adaptive streaming or Digital Rights Management (DRM) playback. To add these features, you’ll need to download and install the Media Feature Pack from the Microsoft Download Center, as well as an app that uses PlayReady DRM from the Microsoft Store, such as the Xbox Music app or Xbox Video app. The app must be installed to specifically turn on DRM features, while all other media features are installed with the Media Feature Pack.
