You can refer to the following methods to reject the update before the shutdown.
01 Power off with the power button.
The reason why the automatic system upgrade is triggered is actually because we are used to using the shutdown command on the boot menu. So, as long as you switch to the power button to turn off, you can skip the automatic update of your computer.
Open the Control Panel - Power Options, click "Select the function of the power button" in the list on the left; Select the "Power Off" option in the "When the Power Button is Pressed" list, then click the "Save Changes" button and you're done.
02Clear the distribution folder.
Since the update file will be automatically sent to the system's distribution folder first, to reject the automatic installation, first disable the relevant distribution service items, and then clear the contents of the distribution folder, so that the automatic upgrade cannot be performed when the computer is shut down.
Related services are prohibited.
net stop wuauserv
net stop cryptsvc
net stop bits
net stop msiserver
Delete the contents of the distribution folder. Locate the distribution folder "C: Windows Software Distribution Download" in File Explorer, select all the folders under that folder, and then press the shift+del key combination (or select the permanent delete command from the dashboard) to perform the permanent deletion operation.
After the above command is executed, the automatic upgrade will not be performed when the machine is shut down, since the distribution file no longer exists.
net start wuauserv
net start cryptsvc
net start bits
net start msiserver

It doesn't have to be a program in the background.
When you click "Shut down the computer", the Windows system will send a message to each application, informing them to close by themselves, and some programs will process this message normally to perform the shutdown process normally (for example, some programs need to save the configuration before closing, so the system notifies the application to close itself, rather than the system forcing these programs to close, because the application has to be left time to process its own affairs); For other programs, if for some reason they can't respond to the system's notification message immediately (e.g., they are working on a time-consuming transaction that they don't have time to respond), the system will pop up a dialog box asking the user if they want to force close (end immediately), and if the user chooses to end immediately, the system will force the program to close. >>>More
