I did a registry backup with the Windows Repair AIO v1.6.4.
I tried then to restore it but the problem is that the registry backup folder doesn't contain the needed "ERDNT.EXE". I tried to manually add them by running the ERUNT to make a backup and copy the needed files to the backup folder made by AIO. I managed to restore the registry but had many error messages concerning some missing backup files.
Can you take a look what's wrong with the ERUNT and why it didn't create the needed .exe files to restore the actual backup.
Also, will the ERUNT make a full registry backup? Now it doesn't let the user configure it, so I can't know what all it includes in the backup.
