The Fast Startup function can make the Windows 10 system faster at startup. Based on the user experience, Microsoft will enable fast startup in the system by default.
This function can shorten the startup time of our operating system to 8 ~ 15 seconds. The reason for such a quick start is that the operating system will not be completely shut down.
The combination of hibernation and shutdown properties allows the device to start faster, but quick startup sometimes also affects the normal installation of Windows 10 cumulative updates.
In the latest support document, Microsoft stated that a quick start may cause confusion in system updates, and the company will fix the issue in a future version.
Microsoft said that under normal circumstances, after installing the cumulative update, you must wait for the system to restart to complete the installation. This requires the operating system to be completely shut down and restarted.
The Fast Startup does not completely shut down the computer but has the property of hybrid hibernation, which causes the system to always fail to deploy the update.
“Without a full shutdown, those pending operations won’t be processed. As a result, these update installations will not complete. Full shutdown only occurs when you restart a computer or when other event causes the computer to process a full shutdown,” Microsoft said.
In response to this problem, Microsoft will fix it in a future version of Windows 10. The repair solution may be to perform a hard shutdown and hard restart of the update installation.
For users who have been unable to perform the cumulative update due to this problem, you can temporarily turn off Fast Startup after completing the installation of the update and then turn on Fast Startup.
