Finally, Windows 10 is here and Battery Level has some new updates!
For those who upgraded from the Windows 8 version, you will need to run a command to remove the scheduled task. If you did not know, Windows 8 did not have any access to the power APIs from a store app, so it was necessary to have a batch file do the work.
To manually remove this old task run the following command from a command prompt. Type cmd into the Search bar next to the Start button, right click the icon and select Run As Administrator.
To remove the old task:
schtasks /delete /f /tn "BatteryLevel"
Some people have had issues installing the batch file, usually due to non english characters in user name paths.
Here are some instructions on manually setting up the schedule which should make Battery Level work for you
