Windows: cd/dvd drive doesn't work (error code 19)

Your CD/DVD drive isn't working (not showing up in My Computer)? You got the following error:

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"

? If you right click My Computer, click manage, and click device manager, your CD/DVD entry should have a yield sign over it

There's a good chance you can fix it by deleting the UpperFilters and LowerFilters registries in regedit.

1) Run regedit.exe: open Run (Windows Key+R), type regedit, hit enter.
PS, "Windows Key" is also known as "Meta"

2) In regedit's tree (the left panel), navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class. Do this by highlighting HKEY_LOCAL_MACHINE and pressing right to expand the tree, etc.

3) Once you get to Class, find this specific Key: {4d36e965-e325-11ce-bfc1-08002be10318}. It should say "CDROM" in the right panel

4) Delete the LowerFilters and UpperFilters registry values (highlight them and press delete)

5) Restart your computer
