Turn on inline autocomplete for File Explorer of Windows 8.1

Today, I am going to share with you a brilliant tip which will significantly improve the usability of File Explorer in Windows 8.1. The inline autocomplete feature will save a lot of your time when you work with the Run or Open/Save File dialogs. Let's see the details.

When you begin typing something in the Run dialog, it tries to suggest you some autocomplete values, which show as a dropdown list. For example:
Run dialogThe same thing happens when you are trying to open a file (or save some document). When you type a few letters, Windows suggests you a name from the files that are already present in the folder:

There is an option for File Explorer which can significantly improve this behavior. It is called "inline autocomplete". When enabled, it will automatically add those suggestions right in the text field besides the dropdown list, so you don't even have to type the full text or select it from the dropdown. In the example, I typed just one letter and the rest got filled in automatically:

This is an awesome feature and is actually present in Windows since Windows 98/IE4 days. Inline autocomplete was removed in Internet Explorer 8 but returned in newer versions of IE.

There are two ways to enable this useful inline autocomplete feature.

Enable inline autocompletion using Internet Options

For some strange reason, the option that controls the File Explorer behavior is located in Internet Options and not Folder Options. To change it from there, do the following:

  1. Open the Internet Options dialog. It can be opened via the Control Panel (Control Panel\Network and Internet\Internet Options):
    Or, you can launch it directly from Internet Explorer. In Internet Explorer, press F10 on the keyboard to display the main menu. Choose Tools -> Internet Options:

    The Internet Options window will appear on the screen:

  2. Switch to the Advanced tab. Locate and enable the setting 'Use inline Autocomplete in File Explorer and Run dialog' (under the Browsing section):

That's it. Enjoy improved autocomplete functionality in your apps. Microsoft has also split it into 2 options now: one for File Explorer's Run dialog and address bar, and another for Internet Explorer's address bar.

Enable inline autocompletion using a Registry tweak (the geeky way)

  1. Open the Registry editor (see how).
  2. Go to the following key:

    Tip: You can access any desired Registry key with one click. If this key doesn't exist, just create it.

  3. Create a string value named Append Completion and set its value to yes:
  4. Close all Explorer windows and restart Explorer. Alternatively, instead of restarting Explorer.exe, you can also log off and log back in.

That's it.
