Microsoft removed updating controls when it released the Windows 10 operating systems so that it has become less trivial to set the updating process to manual or disable updates altogether. This is true especially when it comes to Windows 10 Home.
One of the better solutions to regain controls over updates was to disable the Windows Update service, and enable it only when you wanted the system to find and install updates.
Microsoft changed that workaround in the Fall Creators Update version of Windows 10 however closing that loophole effectively.
There is another option that is still available, but it requires changing permissions of the program that is responsible for the update checks. Good news is that this won't affect manual checks for updates, but that it will prevent any automatic checks for updates.
There is also a reset option available, but I recommended that you create a backup of the system partition before you make the changes to the Windows 10 system.
Windows 10 has a task that uses the program C:\Windows\System32\UsoClient.exe to check for updates regularly and automatically.
You find the task under Task Scheduler Library > Microsoft > Windows > UpdateOrchestrator > Schedule Scan in the Windows Task Scheduler.
The task has several triggers: one that runs it once per day, one that runs it aver event log id 8202, and the third is a custom trigger.
The following workaround removes all permissions from the file UsoClient.exe. The update check that is triggered by tasks fails because of this.
Note that this won't affect Windows Defender signature updates, as those will still be downloaded and installed automatically.
You should get success messages, but you can verify that all permissions have been removed by right-clicking on 'C:\Windows\System32\UsoClient.exe, selecting properties from the context menu, and switching to the Security tab when the properties window opens.
Next time when Windows 10 triggers the event, you should get a "access is denied" error message under last run result in the UpdateOrchestrator task listing.
You can still run update scans manually by opening Settings > Update & Security.
You can restore the permissions of the file at any time:
Now You: No, manual or automatic updates? How is your system configured? (Thanks Deskmodder)Advertisement
