You can configure your system to wake only for important scheduled tasks. If you’re working on a laptop, the Wake Timers can be disabled, which means your laptop won’t wake up unnecessarily to update & overheat while stuffed in a bag. For people unaware, Wake Timers are your system’s Alarm Clock that pulls the PC out of sleep. What happens further, depends entirely on your PC’s active power profile & wake timers. Technically, your system stays On but conserves very less power.

So, when your PC goes into Sleep Mode, automatically all the actions get stopped & if there are any unsaved docs or opened applications, they are put into memory, keeping the PC into low power mode. Generally, users schedule ‘active hours’ so that Windows doesn’t install updates at inconvenient times. In the worst-case scenario, doing such things could corrupt your Windows OS, and you might have to reinstall it.

Making your system fall asleep while it’s installing Windows 10 Updates is not recommended. The short answer is NO! The moment your PC goes into Sleep Mode, it enters into a low power mode & all operations go on hold. Will Windows 10 Update Even If I Put My PC On Sleep Mode?
