Today, when I was browsing my files, I noticed that for every folder, its right-click context menu includes an option to open it in a new window. I have never used this option. Some of you may find it useful, while others may not.

Remove Open Folder in new window context menu option
You can set your folders to open in the same window or in different windows from the Folder Options as follows-
Search for Folder Options in Start Search and open it. Then under the General tab, ensure that this option is selected – Open each folder in the same window.
However, if you prefer, you can also remove the “Open in new folder” entry from the context menu in Windows File Explorer.
As I am a big fan of modifying registry entries, I decided to remove the Open in new window option from the Explorer context menu in Windows 11/10. Luckily, I found the registry key that manages this option, and I was finally successful in removing it. The way that worked for me is being shared below.
Do remember to back up your registry or create a system restore point first so that you can always revert, should you wish to.
Manual Registry Method
1. Press Windows Key + R combination, type Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.
2. Navigate here:
HKEY_CLASSES_ROOT\Folder\shell\opennewwindow

3. Now two cases are possible – either you delete/erase Open in new window option or disable its functionality.
4. If you want to delete that option, simply make a backup of key opennewwindow in the left pane highlighted with green and then delete it. It will remove Open in new window option from the context menu.
5. If you want to simply disable its functionality, look out for the DWORD named LaunchExplorerFlags, in the right pane as shown in the image above.
6. Double click on it or Modify it and use the following data for Value Data section:
- Insert 0 – To disable Open in new window function
- Insert 1 – To Enable Open in new window function (Default)

7. Close the Registry Editor, restart explorer.exe and you’ll get to see the results.
