Is this the correct 'rescue CD' image file?

So I reinstalled Windows 10 on my SSD. And just now I created an 'image' backup of my current SSD Windows 10. So it's like a 'right at the beginning' image type...if that makes sense.

But before I did that, I opened Macrium and it asked me to make a 'rescue CD'. Now I did this with my internal HD (before I bought the SSD), but I presume as this was a new install of Windows 10 on a new SSD I had to do it again. But this way felt somewhat different.



I dont remember having this icon (iso on desktop) as the iso image to backup. Also, it creates a things on the side of File explorer, under my SSD C drive. Why has it done this? I right click it and hit 'eject' and it goes away, even though its not a CD?

And the 'iso' on the Desktop, I rightclick and select 'Burn disc image' and that has burned it to my CD I inserted...but I didnt do this method last time either. I had to drag the files onto the CD and click burn.

Is everything here ok and normal?

1. MF just saved the Rescue.iso to your desktop.
2. When an .iso is mounted it shows in File Explorer as DVD-Drive, it's actually a Virtual DVD-ROM Drive.
3. It will also be listed in Device Manager (Show Hidden Devices) > DVD/CD-ROM Drives > Microsoft Virtual DVD-ROM.

Note: Every time you mount/eject an .iso it creates a new Microsoft Virtual DVD-ROM in Device Manager, so you can end up with a lot of Microsoft Virtual DVD-ROM. You can right click on the Light Grey ones and uninstall if you like, it'll get recreated next time you mount an .iso.

Ah yes there were 2 greyed out in Device Manager. I just right clicked and uninstalled one, and kept the other.
Is there a need to keep them there? I have 1 but shall I also 'uninstal device' with the other one?

Also, do I need to keep my Macrium key? I was given a 28 digit code but didnt use it when installing Macrium
