How to add hotkeys to Windows 10 system setting toggles?

Question

There are certain system settings that I toggle regularly, such as enabling and disabling HDR or night light. Is it possible to add hotkeys for these or at least somehow toggle them without the settings app?

Answer 1

To turn Night Light on or off requires a Registry change. Save a Reg file for each state and add keyboard shortcuts, e.g through Windows links (shortcuts) or a third-party utility such as Clavier+. Caveat: For security reasons, you'll still need to confirm any Registry change, so it's not a single-click solution.

For HDR, there are a number of Registry keys that might work, but you also might need to create your own application calling HdmiDisplayMode Class
