Microsoft has issued a warning about a serious and long-running “bug” that affects all 800 million Window 10 users. The vulnerability isn’t an actual bug at all, but a deliberate deactivation of Windows 10 Registry backups by Microsoft despite notification from Registry backups that “The operation completed successfully.”
Registry backups are usually a critical component of security for businesses and users. In the event of a system restore failure, the registry backup is all you have to restore operations.
Ghacks discovered the issue. Microsoft confirmed the registry backup was turned off behind the scenes over eight months ago and stated,”Starting in Windows 10, version 1803, Windows no longer automatically backs up the system registry to the RegBack folder. If you browse to the WindowsSystem32configRegBack folder in Windows Explorer, you will still see each registry hive, but each file is 0kb in size.”
Issues like this may be why Microsoft is getting pushback on converting from Windows 7 to Windows 10, despite the End-of-Life plan for Windows 7 in early 2020.
