TerryFox Posted September 12, 2005 Share Posted September 12, 2005 Hi ... I'm having a problem with a registry key that I would like to delete but , for some reason I can't remove it , This is what I'm trying to do 1. Start Registry Editor (Regedt32.exe). 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} When I try I get a error that I cannot delete this key , Does anyone know how I can remove this entry ? TIA Link to comment Share on other sites More sharing options...
Hatefulsorrow Posted September 12, 2005 Share Posted September 12, 2005 One way to remove this would be to do a complete export of your registry and hand remove the entries. Then re-import the edited registry. But this can be dangerious because it may cause the system to crash. Don't know if it would work for sure but it's an idea.

what3v3r Posted September 12, 2005 Share Posted September 12, 2005 if nothing else works, boot with bartpe and open the registry in bartpe's registry editor. Link to comment Share on other sites More sharing options...
Takeshi Posted September 13, 2005 Share Posted September 13, 2005 (edited) This reg key is actually a link to the corresponding ControlSet00N key. One of these is used to boot your PC.The CLSID points to CDROM device.It might be more productive to say what hardware problem exists than just to delete a subkey.I don't know if you can actually delete the subkey but removing the device first might help.PS. In XP, there's no need to use Regedt32.exe any more. Regedit will do. Edited September 13, 2005 by Takeshi Link to comment Share on other sites More sharing options...
