To select your own timeframe, click Change and choose a start and end time.
Navigate to Settings > Update & Security > Windows Update > Change active hours. Take advantage of a feature called Active Hours, which lets you schedule a time for updates and reboots. That's a good way to lose data in open apps. What's worse: if you don't reboot your PC after an update, Windows 10 eventually takes it upon itself to reboot for you.
Windows 10 updates are regular and seemingly never-ending, and pretty much out of the user's control (unless you turn off updates altogether, which is a bad idea).
