that seems to affect power plans on Windows 10. The “balanced”

Windows 10 Build 19043.1151 has also addressed an issue that
prevents gaming services from opening certain games. Similarly,
another bug has been fixed that prevents users from enabling
Input Method Editor (IME) when your device is set to shut down
automatically when the lid of the laptop is closed.
Another issue has been fixed where Windows is unable to detect
internet connectivity when you’re connected to the virtual
private network (VPN). The company has also applied a fix for
an issue that results in printing problems or printouts with

The patch is available for testing in the production channel,

your Microsoft account.
For those unaware, Windows Timeline allows users to keep a
track of their activities across various devices. Timeline was
ditched from Android (Microsoft Launcher) last year and
Microsoft has now retired the sync capability.
