Group Internet Explorer Tabs Into One Icon In Taskbar

One annoying default "feature" of Internet Explorer is it displays each tab as separate taskbar icon. This is unlike other browsers like Chrome and Firefox. To get around this, try the following steps:

1. Tools → Internet Options
2. Under the General tab, click on Tabs button.
3. Make sure 'Show previews for individual tabs in the taskbar' option is unchecked.
   
   
4. Click OK to apply changes.
5. Re-launch Internet Explorer.

IE tabs should now be grouped into one single icon in the taskbar.
