Delete all favorites from Edge?

I've managed to sign out of Windows 10 but that really takes me no where. I've tried opening your bat file but that only brings up Notepad and what you've written. I don't see Powershell anywhere. Waiting for further instructions!
And oh yes, I would like to have the Bookmarks removed only from Edge but not IE if possible. Thanks!

Unblocked it but still getting no further than it opening in Notepad. Extracted it and it puts the file into another directory under Users. Clicking on it there only does the same thing, bringing it up into Notepad.

I'm going to call this a closed case. Obviously, this is not an easy fix. Thanks for the efforts Brink.

Thanks for the persistent effort Brink. I'm away from my computer for a bit but will follow your directions when I get back. Thank you again for this!

There is no way this is easy for me Brink. I'm on site you gave me, but what I'm to download from there is beyond me. It's way too confusing for an amateur like myself. I see one that might come close (in my mind) which is called Bat (Windows Batch File). Is this the one I download? And if so, will running that particular file in itself clear my Bookmarks from Edge (only) or do I have to run this Batch File then run the "Reset Microsoft Edge" after opening the Bat file? Am I confusing you? I know I am!

Brink, when one does a Registry backup and then uses that Backup, does what was put in the Registry remain there even after importing the Backup?
