All Samsung laptops come with a tool called SW Updater that checks for any updates to bloatware that comes pre-installed, along with driver and software updates. While such utilities are available from most vendors, what's unique about Samsung's SW Updater is that it was found to disable Windows Update, preventing Microsoft's default updater tool from finding new updates.
A researcher discovered the problem while debugging Samsung's utility, finding a program called "Disable_Windowsupdate.exe" that constantly monitors the Windows registry to block access to Windows Update. Even if you manually enabled Windows Update, Samsung's program was found to prevent access to the utility after every system restart. The researcher confronted a Samsung customer service representative to confirm that the manufacturer was indeed blocking Windows Update:
Samsung's move to block Windows Update could just be a measure to ensure that any system updates rolled out by Microsoft don't break Samsung-centric bloatware. If you're using a Samsung laptop, all you need to do is uninstall SW Updater and enable Windows Update to continue receiving updates in a timely fashion. Coming on the heels of Lenovo's Superfish incident, this is just another reason why manufacturers should re-consider filling up brand-new machines with bloatware.
