Energy management.exe has 6 known versions, the most recent one is 18.104.22.168. Energy management.exe is run as a standard windows process with the logged in user's account privileges. Anyway, people want to remove whitelists, remove Intel ME and install core/libre-boot. I think based on bios-mods.com that the bios flash updater used crc and encryption on parts of the normal bios (UEFI) aswell. And only somewhat after 2.5 (lenovo) changed to only update.efi files that needs updateing. But I might be mistaken.
If you need to disable System Update scheduled updates on a single machine, you can easily do this manually. Open System Update and then click Schedule updates under the “Advanced” section. Uncheck the box “Enable monthly check for updates”. Congratulations! Your box-unchecking skills are impeccable.
If you need to modify a machine remotely or disable updates on a large number of machines, you’ll probably want to disable scheduled updates in the registry.
To disable/enable automatic updating, locate the following registry key:
Change value “SchedulerAbility” to NO
You are now free from Lenovo’s oppressive updating tyranny.
Enabling Scheduled Updates
