13.10.2009

If your DVD/CD drive is not being recognized by Windows and other software, making it impossible to access it, the problem may come from the registry. This might occur when you installed/uninstalled a software or maybe even the Windows OS itself.

As in this article we will talk about modifying the registries, you have to make sure you follow each step carefully. In addition, it may be a good idea to back up your registry before you start editing the entries. This way, you will be able to restore it if anything bad happens.

1. Go to Start, click All Programs and go to Accessories->Run.
2. Type in “regedit” and press OK.
3. While in the navigation pane, you should now find the „ HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318” entry. Click on that entry.
4. Find the “Upper filters” in the right pane and click on it. If you cannot find it, go to step 6.
5. Go to Edit->Delete and press yes when prompted for delete confirmation.
6. Now you should find the “LowerFilters” entry in the right pane. Delete this entry also. If you did not find the “LowerFilters”, this article cannot help you.
