windows - Using C++ to edit the registry

Question

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_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorerNoDriveTypeAutoRun 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?

Answer 1

• Open the registry : RegOpenKeyEx

• Query the value : RegQueryValueEx

  /* do something with value*/

• Set the value back : RegSetValueEx

• close the registry : RegCloseKey
