You are most welcome DaChew, and thank you for asking as it clears how there is a need to use a clear language, and that is what I sometimes forget.
But still it remains to explain to DocSatan that all the effort was to backup registry with regedit, not because the backup made by regedit is better than Erunt. No, Erunt is much better and could be easily accessed via recovery console. But the question was whether the changes to registry would be preserved/saved by regedit or not. When you run those commands would the registry changes be saved or they would be lost because regedit can't handle .reg file? So backing up registry was not the aim but a test of windows registry editor.
However I leave it as it is now as I feel it is said enough.
