Restoring a registry backup in Windows 10
Microsoft recently reported that regular backups of the system registry are no longer supported in Windows 10 from version 1803. This means that you must re-enable the feature manually to save the registry. The Windows registry contains several low-level settings that control certain features of the operating system.
If you navigate to the RegBack folder, you will notice that each registry hive still exists, but all its files are 0 kb in size.
Last October, the operating system automatically stopped backing up the registry, even though it reported that the backups were complete. At the time, most people thought it was a bug, but Microsoft says the change is in the design and it’s a way to reduce the size of the footprint.
However, the RegBack folder doesn’t take up as much space, probably only a few hundred MB on most systems. Also, there are cheaper storage options these days, so it would make sense that most people will hardly ever use registry backups, and the folder size may increase as backups become corrupted due to system errors.
Why a registry backup is necessary
When your Windows registry is damaged, it can cause crashes, crashes, and startup errors. This is also important for troubleshooting, but Microsoft asks users to rely on system restore points for this purpose.
It also recommends that you create restore points before doing anything that might make your system inoperable or unresponsive, which is more than not doing them at all.
Restoring a registry backup
If you still want registry backups, you must manually re-enable them by using registry editing to change the value of the registry key. Do this:
1. Click the Search button in the lower-left corner of the screen next to the Start menu icon.
regedit.exe and click the search result that appears.
