Summary

Searches for and retrieves a file association-related string from the registry. A wrapper for the [IQueryAssociations] interface.

.

The Windows Shell (Explorer) stores your preference in the following registry key:

.

The problem of leaving behind the registry keys: Since the registry key gets stored in HKEY_CURRENT_USER, every different user on a system will have their own preference saved. If you uninstall the program for one user, you'll leave behind the registry keys for the other users. For example, suppose users X and Y have checked the "Do not show me this dialog again" checkbox, and therefore each have the registry key in their HKEY_CURRENT_USER area. Now user X uninstalls the program. The uninstaller must leave behind the registry key for user Y because that user is not logged in.

.

        "MyApplicationName.exe" // This last argument is the value of the registry key

.

        Console.WriteLine("\nAny changes will not persist a reboot - to do so, remove the font entry from the registry.");

.

                 // registry.

.

You can store the encryption or master keys used by CryptProtectData in a file in the Windows folder or in the system registry so that certain persistent registry implementations will retain the encryption keys after losing and regaining power. See Master Key Storage for more information.

.

Upon successful return, the hProfile member of PROFILEINFO is a registry key handle opened to the root of the user's hive. It has been opened with full access (KEY_ALL_ACCESS). If a service that is impersonating a user needs to read or write to the user's registry file, use this handle instead of HKEY_CURRENT_USER. Do not close the hProfile handle. Instead, pass it to the UnloadUserProfile function. This function closes the handle. You should ensure that all handles to keys in the user's registry hive are closed. If you do not close all open registry handles, the user's profile fails to unload. For more information, see Registry Key Security and Access Rights and Registry Hives.

.

Note that it is your responsibility to load the user's registry hive into the HKEY_USERS registry key with the LoadUserProfile function before calling CreateProcessAsUser. This is because CreateProcessAsUser does not load the specified user's profile into HKEY_USERS. This means that access to information in the HKEY_CURRENT_USER registry key may not produce results consistent with a normal interactive logon.

.

Microsoft changed the UuidCreate function so it no longer uses the machine's MAC address as part of the UUID. Since CoCreateGuid calls UuidCreate to get its GUID, its output also changed. If you still like the GUIDs to be generated in sequential order (helpful for keeping a related group of GUIDs together in the system registry), you can use the UuidCreateSequential function.

Summary

When an application is launched from the registry HKLM\init, that application must call the SignalStarted function to notify the operating system that the application has been launched.

.

dw is an unsigned integer type parameter that corresponds to the launch code of the application in the HKLM\init registry. ie. If the registry value "Launch25" corresponds to the application that you want to launch, the application that you launch should call SignalStarted(25) when it has launched.

You can also look at the configured timeouts at the registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power".
