Notes

• This wizard may be in English only. However, the automatic fix also works for other language versions of Windows.
• If you are not on the computer that has the problem, save the Fix it solution to a flash drive or a CD and then run it on the computer that has the problem.

Then, go to the "Did this fix the problem?" section.

Let me fix it myself

To do this, change the value of the following registry subkeys to 3 (Manual) or 4 (Disabled)：

• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cdrom
  Name: Start
  Type : REG_DWORD
  Data: 3 or 4
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\parport
  Name: Start
  Type : REG_DWORD
  Data: 3 or 4

Note: If the above registry is changed to 4 (Disabled), the related device is not usable because a driver used in the device is not loaded. Therefore, if the device will be used in the future, the above registry should be set as 3 (Manual).
