I have a limited c++ background and I would like to edit the registry. For example, I want to grab the value of HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDriveTypeAutoRun and check to see if 0x20 is in it, and then if it is, subtract 0x20 from it’s value and write it back (and kill and restart explorer.exe but I can figure that out on my own).

How would you do it?

    • Open the registry : RegOpenKeyEx

    • Query the value : RegQueryValueEx

      /* do something with value*/

    • Set the value back : RegSetValueEx

    • close the registry : RegCloseKey
