Windows 10's Automatic Maintenance featureTime: Jan. 15, 2018 From: SCDKey
In Microsoft Windows 10 Pro OEM CD-KEY GLOBAL, automatic maintenance is a feature that helps keep your computer healthy and optimized by combining and performing all your maintenance tasks without compromising performance or energy efficiency.
In general, automatic system optimization occurs once a day when you are not actively using your device. However, it is possible to change the time and other settings to avoid losing a maintenance plan because the computer has shut down, been used actively, or has not behaved as expected.
Automatic maintenance is a series of related tasks that run by default at 2:00 a.m. everyday. These tasks run simultaneously in the background, but only when the computer is on and inactive. If your device is in sleep mode and plugged into a power source, Windows 10 can also turn it back on for maintenance and then return it to hibernation.
It should be noted that the updates are more intrusive in Windows 10 and are even downloaded and installed outside of the usual maintenance plan. Therefore, you can not use this feature to disable Windows Update.
Automatic maintenance is usually a useful feature and you must continue to enable it so that your computer works properly. However, if you notice problems such as the unexpected impact on performance, sudden crashes, and other problems, you may want to disable this feature.
