So, when you type regback copy -.- .. , the command interpreter sees:
This backs up the Registry along with system files. regback copy -.- .. not working
'regback' is not recognized as an internal or external command, operable program or batch file. So, when you type regback copy -
reg save HKLM\Software C:\Backup\software.hive reg save HKLM\Software C:\Backup\software
Prior to Windows 10 version 1803, the Windows Task Scheduler ran a task called "RegIdleBackup." This task would automatically backup the registry hives to the C:\Windows\System32\config\RegBack folder periodically. This was a safety net for power users and administrators.
Once enabled, Windows will create a backup in the RegBack folder during the next maintenance cycle, and your command line tricks will work again.
The regback copy command ( copy * ..\* ) is failing primarily because in Windows 10 (version 1803 and later) and Windows 11 . In these versions, the RegBack folder still exists but typically contains files that are 0 KB in size, meaning there is no data to restore. Why the Copy Fails
