Restore Missing CD or DVD Drive

Reports have filtered in that CD or DVD drives will suddenly cease to exist in XP AND windows 7 Systemssystems. Most often this has been reported in conjunction with program installations and Windows upgrades, but it has also happened for no apparent reason. This tweak will restore the missing drives after a reboot.

[Start] [Run] [Regedit] WINDOWS 7  [ Start ], and in bottom it says Search programs and files, (this is the Run in Win 7)
Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
Key Name: {4D36E965-E325-11CE-BFC1-08002BE10318}
Value Data: [Delete All Value Data from UpperFilters and LowerFilters] Note: Do not delete the Key or the Multi-String Values. Delete only the data values.
Exit Registry and Reboot

When I tryed this I could only find the LowerFilters Value Data, so just took that out and it worked also. So try either or both.
