Fix Registry

A little mistake in the Registry can make your computer unstable. Similarly, when backup and restore settings are incorrectly changed, it leads to error 0x80070643.

Using RegEdit, create a new sub key named “FilesNotToBackup”. (It’s subkey; not string value). After creating that sub key, close the dialog and use Services.msc tool to start the service named “Background Intelligent Transfer Service”. In case it is already running, stop and restart it.
