It always is, it only becomes enabled once an update has been downloaded and awaiting a restart. Active Hours is one you can set at any time.

Active hours lets Windows know when you usually use this device. When a restart is necessary to finish installing an update, Windows won't automatically restart your device during active hours.

If a restart is not currently scheduled by Windows Update, then the restart options below will be grayed out.

Perhaps not, I think we may end up going outside Barabba's comfort zone :)

For my Home machine I always get in first with a manual check before windows update get's round to checking for and installing updates. That way I get to choose the time an update is installed and never suffer a surprise restart.

Check for and Install Windows Update in Windows 10

@Barabba, it may help to know that these updates are routinely issued on the second Tuesday of each month at around 10AM (Redmond, USA time). Occasionally an update is issued 'out of band', so it's worth checking for updates before beginning any important/lengthy work.
