On my HP laptop with factory installed Windows 10 with the latest updates, opening or closing the CD/DVD device consistently causes the screen background to change from the Autumn scene to black. Hitting the keys Start-Tab shows small version of whatever screens (sessions, whatever they are called -- can have multiple such screens), each with its proper background and a left click on one of those will give a correct screen. In addition the background of the screen from Start-Tab has Autumn, and a left click on part of that background give a correct screen. When this error first occurred, just after a Windows 10 update, in Firefox a Web page caused Windows to display a pop-window about a security problem. The Autumn background went to black, and the desktop icons were scattered across the desktop. I ran a "quick scan" and a "full scan", and they found no problems. I put the icons back where they belong, and they have stayed there. Looks like the most recent Windows 10 Home Edition update has a bug that causes the screen background to go to black. Starting Firefox puts up a pop up window asking if I want to permit Firefox to "change" my system or some such. As this popup is displayed, all other windows have been minimized, and the screen background is black. If I left click on the push button "No", then Firefox runs and the background and all my windows are restored.

Black desktop usually is a sign of a Windows licensing/activation issue. I'd guess when your DVD drive opens, the driver somehow reloads, and windows sees a different serial number, so the windows license is no longer valid. It then auto-re-licenses itself a few minutes later, provided it has an internet connection and the desktop background returns.

  That’s interesting. I would have guessed something like an unsigned driver or malware. I don’t think just one device change would be enough to cause a reactivation, but maybe repeated ones. I’ve changed CPU, GPU, optical drives, RAM on a system with no reactivation. Motherboard seems more likely to trigger it, but that doesn’t seem likely in this case. More info would help, but in the meantime OP should scan for malware with RogueKiller or at least ADW Cleaner/Malwarebytes/ESET or another decent alternative.

If you don’t have the new update, get it after making a backup. Then run these commands in an elevated command prompt to attempt repairs to your Windows 10. Make sure you restart and have all programs closed when you do this. dism /online /cleanup-image /restorehealth sfc /scannow Run the first one, then run the second one until it says no problems or violations found or something to that effect. Then reboot as soon as you can.
