The issue arises from a bug in PowerToys causing Windows 11 to automatically change themes to light or dark.
A recent issue has been discovered in PowerToys. A new function named Light Switch was released and quietly activated auto-switching between light and dark themes based on the time of day. This change should not have been enabled by default, particularly without first notifying users. https://www.windowslatest.com/2025/10/19...powertoys/ This month's updates also brought several other problems. https://www.windowslatest.com/2025/10/18...ll-errors/ https://www.windowslatest.com/2025/10/18...ery-input/ It seems our QA team is now handling the end users.
It seems the settings were activated, yet no changes to the theme appeared.
