  1. Windows 10 has a dark themed UWP File Explorer app built in. You need to create a new shortcut on the desktop and either copy and paste (or type) this into the location box:

    explorer shell:AppsFolderc5e2524a-ea46-4f67-841f-6a9465d9d515_cw5n1h2txyewy!App

    Click Next and give it a name, like Explorer or Dark Explorer. Then click Finish and double click the new icon and you have the hidden dark UWP File Explorer.

    Next major update of Windows 10 will have a proper dark Windows File Explorer.
