256986 Description of the Microsoft Windows registry



SYMPTOMS
After you install Microsoft Windows XP or Microsoft Windows Beta 2, the CD-ROM drive, the DVD-ROM drive, or CD-ROM R/W drive may not be visible in the My Computer window. Additionally, there may be question marks on the devices that are listed under CD-ROM drives in Device Manager.



CAUSE
An incorrect device driver was installed for the CD-ROM device.



RESOLUTION
To resolve this behavior, use the following methods in the order in which they are presented.

Method 1: Remove the registry entry
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Note If you had installed multiple CD-writing software products on your computer, you need to uninstall the software products before you remove the registry keys.  Click Start, and then click Run. In the Open box, type regedit, and then click OK. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Class/{4d36e965-e325-11ce-bfc1-08002be10318}

 On the File menu, click Export. In the File name box, type savedkey, and then click Save. Click the REG_MULTI_SZ data type UpperFilters, and then click Delete on the Edit menu. When you are prompted to confirm the deletion, click Yes.

Note If this data type is missing, go to Method 2.</li> Click the REG_MULTI_SZ data type LowerFilters, and then click Delete on the Edit menu. When you are prompted to confirm the deletion, click Yes.</li> Quit Registry Editor, and then restart the computer.</li></ol>

Method 2: Replace the existing driver

 * 1) Click Start, and then click Control Panel.
 * 2) If Control Panel is in Category view, click Performance and Maintenance, and then click System.

If Control Panel is in Classic view, double-click System.
 * 1) On the Hardware tab, click Device Manager.

Note In Windows Vista Beta 2, click Device Manager in the left pane. If a dialog box appears that describes permissions, click Continue.
 * 1) Click the drive with the question mark next to it.
 * 2) On the Action menu, click Uninstall. When you are prompted to confirm the removal, click OK.
 * 3) Repeat steps 4 through 5 for any other drives with question marks.
 * 4) On the Action menu, click Scan for hardware changes.

Note If Windows XP cannot locate the driver for your device, the device may not be supported by Windows XP. To see the list of supported devices, see the most recent Windows Hardware Compatibility List (HCL) at the following Microsoft Web site:

http://www.microsoft.com/whdc/hcl/default.mspx

Although Microsoft does not encourage the use of devices that are not on the Hardware Compatibility List, sometimes you can obtain a Windows XP-compatible driver by contacting the device manufacturer directly.
