Wake up unresponsive DVD drives, restore transparency effects and keep clocks in sync
Guest OS doesn’t respond to new CDs/DVDs
If you’re using VirtualBox to run a guest operating system (OS), such as an older version of Windows, you may find it fails to recognise your optical (CD/DVD) drive. A quick Registry tweak should fix the problem. Back up the Registry first, by creating a system restore point. Then, in your guest OS, type regedit into Start and press Enter to open Registry Editor. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\cdrom. Right-click AutoRun in the right-hand pane and choose Modify. Change the ‘Value data’ field to ‘1’ and then restart the guest OS.
