Welcome to the Community Forums!
This kind of problem happens when the machine detects a virtual drive that was used on this machine.
Have you installed programs such as (MagicISO) to be able to open ISO files recently?
We'll wait for your response. Thanks.

Adding to what Jack said, Windows 10 can open ISOs directly in Windows Explorer. This will also cause a virtual CD/DVD to appear.

As previously mentioned, virtual drives only appear when you install a software which is able to mount disc images. When using the Windows Explorer to do this, it is supposed to disappear. It's an option that exists since ~2012 in Windows 8, and I have never seen it fail to entirely dismount the virtual image. Did you perhaps install any software like Daemon Tools that mounts/edits ISOs?
