This will prevent windows update from waking up your computer / laptop from sleep mode at 4AM and applying a update. Scroll down to Sleep > Allow Wake Timers > Setting: Disabled (default is enabled)
On your selected preferred plans > change plan settings On the right side > Additional Power Settings Windows Search > Power > Power and Sleep Settings > Go to Task Scheduler > Task Scheduler Library > Microsoft > Windows > UpdateOrchestrator
