Samsung claims that this is to “help your windows configuration settings” and it was discovered by a researcher and Microsoft MVP .
It comes with SWUpdate, Samsung’s bloatware that comes with all their PCs.
Samsung’s says that by enabling Windows updates, you install the Default Drivers for all the hardware for a laptop which may or may not work. For example if there is USB 3.0 on laptop, the ports may not work with the installation of updates. So to prevent this, SW Update tool will prevent the Windows updates.
That may be true, but Windows Update is also responsible for critical security updates. And come Windows 10, it will also be responsible for new versions of the OS.
SWUpdate went unnoticed because it wasn’t permanently disabling the update process. People could still start and stop it manually, though the automatic service would get disabled again with every reboot.
