UPDATE: Automatically disables the Windows Experience Service if it will not cause issues on your version of Windows.
But, as it turns out, doesn't always work. Be sure to open gpedit.msc and toggle a setting between enabled/disabled to force the group policy to activate.
E-Tweaks 2.0 is collection of batch scripts I've made for Windows 7 that aims to improve performance by disabling some background services and performing a few minor tweaks.
E-Tweaks.bat - Disables services that most users do not use. Also performs the following tweaks: 1) Shows File Extensions 2) Disables Action Center 3) Disables Administrative Shares 4) Disables Reboot on BSOD 5) Disables Autorun on All Drives
PowerSchemes.bat - This script's primary function is to disable the "Sleep feature" that Windows Vista and 7 has implemented. In addition to using extra power, the sleep feature can sometimes cause computers to hang when they are trying to wake. I've made this script to remove this so called feature easily. It will also change your Power Profile to "High Performance"
If the Windows Experience Service can successfully be disabled, the following other tweaks are applied to the Group Policy:
