ahem..... Settings offers Update & Security which offers Windows Update which offers Update history, and under Update settings there is change active hours (don't restart while busy), Restart options (handles logins etc) and Advanced options (what else gets updated when Windows updates) and Choose how updates are delivered (decide how many more machines on your network suffer at the same time!). Nothing to stop the OS updating or manually decide which bits to do. It clearly states that Available updates will be downloaded and installed automatically.
Looking at the Update history shows that all of the incremental security updates go through OK but the larger updates often take several tries, the number is getting bigger.
