Abstract: http://hi.baidu.com/gzqzbz/item/8c0e97b7e1964975244b093f

The optical drive of the computer is used properly. It cannot be used because of software installation or other reasons. It is not reflected when you put the disk in. The light of the optical drive lit up when I first got in.
Open the Device Manager and there is a yellow exclamation point in the DVD/CD-ROM item, and the following text appears in its properties: "Windows cannot load the device driver for this hardwareProgram. The driver may be corrupted or missing. "Re-uninstall the installation is useless.

Solution:

1. Open "Registry Editor" (run: Regedit ).
2. Find the upperfilters value under the following registry key:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ class \ {4d36e965-e325-11ce-bfc1-08002be10318}FindUpperfilters
3. On the editing menu, click Delete, and then click OK.
4. Find the value of lowerfilters under the same registry key:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ class \ {4d36e965-e325-11ce-bfc1-08002be10318}FindLowerfilters
5. On the editing menu, click Delete, and then click OK.
6. Exit "Registry Editor ". Note: After deleting the upperfilters value and lowerfilters value, if you notice that a specific program (such as CD recording software) has lost its function, you may need to reinstall the software. If the problem persists, consult the software supplier for help.
7. restart the computer.

In the registry, all drivers under HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ class \ are drivers. If other drivers cannot be installed, you can delete the corresponding project here, after the instance is restarted, it is automatically installed.

Warning improper use of "Registry Editor" can cause serious problems that may require reinstalling the operating system. Microsoft does not guarantee that it can solve problems caused by improper use of the Registry Editor. Use the Registry Editor at your own risk.
