The registry editor is an integrated utility that comes with the Windows 10 operating system. It contains all hierarchical data configurations for the Windows 10 operating system, its kernel, drivers, application programs installed on it, and much more. This means that some settings that cannot be switched from the user interface can be changed using the registry editor – if the right keys are found and changed if necessary. But the main problem is that in many cases, the user has to restart his computer to find the changes in the registry. But today, we will discuss how we can disconnect from this time by running the restart process and accelerating it.

Windows loads the content of many registry keys at startup or when connecting. If you later change one of them, the change will have no effect until you disconnect and reconnect.

It is generally not possible to make registry changes immediately and without restarting. Most programs are only read from the register during the boot process. There are 2 possibilities:

1. restart the program OR
2. Define a named event to notify the program to reload the modified registry settings. To do this, the program must wait for the named event.

It is not possible to restart a system process without a software or hardware reset and very few support the signalling mechanism (option 2 above).

Force changes to the registry without requiring a complete restart.

  1. Press CTRL-CLEAR to access the Windows task list.
  2. Select Explorer and click Finish Task.
  3. When the shutdown screen appears, click Cancel.
  4. After a few seconds, an error message appears. Click on Finish the task.

Windows will then reload the Explorer and all the new registry settings.


Registry changes take effect immediately, but many applications (and some operating system components) read the registry settings only once at first startup, so registry changes only take effect after the application / machine restarts.

If you are responsible for maintaining an application that uses registry settings and you want your application to respond immediately to registry changes without having to restart, you can receive WMI notifications when the registry is changed.

If you are trying to update a registry key for another application (or component of the operating system) and you want the changes to take effect immediately, it is because of this application – note that there is probably no full load that you can run unless this application already supports it, or you can convince application managers to change the application for you.
