   6 My sister asked me to have a look at her notebook (a Medion Akoya P6612
   7 with Windows Vista) because the CDROM drive wouldn’t work, and it was
   8 not even displayed in the Windows Explorer. I looked into the Device
   9 Manager and noticed that the CDROM device (TSSTCorp SN-S083a) was
  10 displayed with a small yellow exclamation mark besides its icon, and it
  11 said on the Properties page that the device could not be started and
  12 referred to Code 39. Reinstalling the drivers had no effect, but after I
  13 had a little chat with [Big Blue G][0], I found a [howto entry][1] which
  14 suggested the following:
  15
  16 1. Be logged in with an administrator account
  17 2. Open the Registry Editor (choose it from the Start Menu or press
  18    Win+R and type `regedit`)
  19 3. Navigate to
  20    `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}`
  21 4. Then, in the right pane, delete all of the following keys:
  22    * UpperFilters
  23    * LowerFilters
  24    * UpperFilters.bak
  25    * LowerFilters.bak
  26 5. Restart your computer
  27
  28 This worked fine for us.
