Disable Creation of Last Known Good Configuration

This feature allows you to disable or enable the creation of the Last Known Good Configuration, which stores a copy of the configuration after each successful boot-up.

“Last Known Good Configuration” (LKGC) is a recovery option Microsoft built into all versions of Windows (starting with XP), available from the Advanced Boot Options menu, and can be a valuable asset when attempting to recover a PC that isn’t working correctly.

Generally, the LKGC is recreated after each successful logon.

When starting up the operating system, it is possible to instruct it to use an older backup of parts of the Windows registry that are often misconfigured and responsible for many bootup problems. This state is known as LKGC, and is essential in allowing you to access your computer after a failed update, driver installation, software setup, or malware activity.
