We know that there are benefits of hibernating your computer instead of shutting down, but shutting down periodically does have its benefits. Many critical Windows updates require you to restart your computer so that system files that are currently in use can be updated. This is annoying but a necessary step to ensure that your Windows PC is not susceptible to bugs and security vulnerabilities addressed in these updates.
Before shutting down your computer look for any notifications that updates are ready to be installed. If any such notification is present expect your computer to take a little longer to shut down. Also expect your computer to take a longer time to start up on the next boot because files are being updated.
