The Win7 system does not recognize the old DVD drive profile

  
Method 1: Open the Registry Editor and navigate to the [HKEY_LOCAL_MACHINE/SYSTEM/Current ControlSet/Control/Class/{4D36E965-E325-11CE-BFC1-08002BE10318}] item, directly to “ The Upperfilter” item and the “Loweverfilter” item are deleted, and the computer can be restarted.
Note: This method may cause some programs to malfunction after deleting the two key values. For example, the CD burning program may not be usable. Usually, just reinstall the latest version of the program to solve the problem.
Method 2: Open the Command Prompt window with administrator privileges, enter the following command "bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS" (without the outer quotes), after the execution is successful, you can solve.
Summary: The first method can be solved temporarily. I recommend using the first method to back up the registry before operating to prevent unnecessary risks. The second method is relatively easy to operate, and the risk of modifying the registry is eliminated. Users may wish to try the second method.
