A newly surfaced problem in PowerToys 0.95.0 is causing the Light Switch utility on Windows 11 to revert manual light/dark theme changes back to the active schedule. The behavior is documented in an open issue on Microsoft’s PowerToys tracker.
The report describes Light Switch flipping themes correctly with a hotkey, then switching back a few seconds later to whatever the timer is set to. The item is labeled as a bug and still awaiting triage.
New features in PowerToys Light Switch
Light Switch is designed to automate Windows theme changes on a schedule and provide a hotkey to toggle between light and dark on demand. In practice, the schedule appears to take precedence in version 0.95.0 when it’s enabled, overriding a user’s manual switch shortly after it’s applied.
Known issue in PowerToys 0.95.0
The report details consistent behavior where a manual toggle doesn’t persist if a timer is active:
“Timer was set to dark mode. I pressed the hot key to change to light mode, and it changes it back to dark mode after a few seconds. Same happens when the timer is set to light mode and I manually press the hot key to dark mode.”
The issue suggests there’s no way to disable the schedule entirely in the current implementation, so the timer continues to reassert control after a hotkey change. It remains open with the labels “Issue-Bug,” “Needs-Triage,” and “duplicate.”
The behavior was reported on Windows 11 Pro with PowerToys 0.95.0. The module impacted is Light Switch, and the app was installed via PowerToys’ built-in auto-update.
