How to Add or Remove Internet Explorer from Power Options in Windows
The JavaScript Timer Frequency setting under the Internet Explorer power option can slow down the java script animations and execution in Internet Explorer which in turn can save battery life. If you want faster browsing in Internet Explorer, then you might want to change this setting to "maximum performance" in power settings. Slower performance is a compromise to save battery life. By default, when using a PC on battery, Internet Explorer will automatically switch to "maximum power savings" for JavaScript Timer Frequency.
This tutorial will show you how to add or remove Internet Explorer and its sub JavaScript Timer Frequency setting in Power Options for all users in Windows 7, Windows 8, and Windows 10.
You must be signed in as an administrator to add or remove this setting in Power Options.
Internet Explorer 11 will be retired on June 15, 2022 in Windows 10
