🔳 Microsoft is working on a built-in feature that would let Windows 11 switch between light and dark themes on a schedule. Code found in an Experimental Channel build suggests it may support idle-based switching and location-based scheduling.
The core of the feature is in the new file, c:\windows\system32\Windows.Shell.AutoDarkMode.dll

The following features are planned:
* A schedule.
* The themes can only switch when the PC is idle, i.e. you are not doing any work.

Moreover, the strings state that there will be conditions to prevent the device from changing the theme. Also, theme switching can be location-based.

"Schedule auto mode"
"Mode only changes when PC is idle"
"This prevents the mode from changing while you're working or in meetings"
"Turn on location services to automatically schedule dark mode. When location services are turned off, dark mode is active from [START] to [END]."

Microsoft has not announced the feature yet, but users can already achieve similar results with registry tweaks + Task Scheduler or third-party tools like Auto Dark Mode.
