The Windows 10 April 2018 update shut down the automatic backup process for the Windows 10 log file, leaving normal PC users more vulnerable than before.
The Windows 10 April 2018 update made many changes to the way the operating system works on your PC, and it is possible that more than a few have gone unnoticed. One of the changes below the radar may have been the fact that Microsoft decided not to automatically back up the Windows 10 log file; It is a change in the behavior of the operating system that could have serious consequences for the unsuspecting.
The reason for consensus was that Microsoft wanted to reduce the memory footprint on local hard drives, probably because many of us are using SSDs with smaller capacities than their mechanical hard drive pairs these days. While that sounds reasonable, it means that typical PC users no longer have a backup copy of the easily available Windows 10 log file. We can change that.
This tutorial shows you how to adjust the Windows 10 log file to enable automatic backup of the Windows 10 log file, returning to the way it used to be.

How to enable automatic backup of the log file  You can see for yourself where the backup copy of the Windows 10 log file should be located using File Explorer to navigate to this Windows directory on the operating system drive (usually C :).

Double-click EnablePeriodicBackup in the right panel and change the value to "1", as shown in Figure D .
Click OK to complete the process and then Exit the regedit application. You will have to restart your PC for its new configuration to take effect.
From now on, Windows 10 will create a backup copy of the log file in the RegBack folder we saw earlier ( Figure E ).
Windows 10 will also configure a task in the Task Scheduler to periodically update the backed up log file as needed, which should give you peace of mind if you will ever find it You need to troubleshoot your computer.
