Tips & Tricks

The CD/DVD drive no longer appears in Windows 10 and 11

• Windows 10/11

System registry: first make a backup copy of the registry.

If Windows 10 or 11 no longer sees the CD/DVD drive, you can try with the command prompt.

1. Open a command prompt as administrator: type “command prompt” in the Search box, right-click the matching entry and choose “Run as administrator”.
2. Type this command and press Enter:

   reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001

3. Close the command prompt and restart the system, so that the CD and DVD drives are detected.

If the drive still does not appear, try this other solution:

1. In Windows search for and open regedit. Select “Computer” in the main window.
2. Go to the system path:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class

3. Here find the following key and delete the values LowerFilters and UpperFilters:

   4D36E965-E325-11CE-BFC1-08002BE10318

4. Exit regedit and restart the system.

Alternatively you can download the file that does everything by itself (dvdGhost.reg). After running it and confirming that you want to add the change, open the command prompt as administrator, run the command “sfc /scannow” and then restart.
