value related to cd/dvd rom. PLz help me to fiind upper value . I know what
is lower filter value.

To resolve your issue, follow these steps:

1. Start Registry Editor (Regedt32.exe).
[Start > Run and type: REGEDIT , and hit enter]

2. Locate the UpperFilters value under the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318}

3. On the Edit menu, click Delete, and then click OK.

4. Locate the LowerFilters value under the same key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318}

5. On the Edit menu, click Delete, and then click OK.

6. Quit Registry Editor.NOTE: After you remove the Upperfilters value and
the Lowerfilters value,
if you notice lost functionality in a particular program, such as CD
recording software, you may need
to reinstall that software. If the problem recurs, consult with the software
vendor for assistance.
7. Restart your computer.
