Once you disable the fast startup, it is going to fix the CPU uptime, even though I don’t care about the fast startup but sometimes a shutdown should fix an error. But because of the fast startup it is not going to fix the error, unless you restart the computer or you have to disable it and let the CPU rest for a bit. Before getting into disabling the Fast Startup, you need to learn What is Fast Startup, how it works and what are the pros and cons of this feature. Learn How to check the CPU Up time on your windows too.

What is Fast Startup (Pros & Cons) and How it works?

As far as I know with Windows 10 Microsoft introduced the fast startup which is increasing the startup process of your Windows. Apparently this is really a good and handy feature to quickly access your computer without wasting a lot of time. But sometimes it has a backlash on the users too. Specifically since it is not completely shutting down your computer instead it is putting your computer into a hibernation mode and when your computer restart it automatically grabs the files of the hibernation and you’ll be on your windows very quickly.

What is the backlash, well the backlash is that since it is putting your computer into into the hibernation mode the CPU is not completely shutting down. Instead CPU is totally up and running even if your computer is shut down. There are couple of methods that you can check the CPU up time how many days, minutes and weeks it has been running without completely shutting down. This is the setting which is not letting CPU to rest for a while.

The other backlash of using fast startup is that updates require a full shut down of the computer. And if the fast startup is enabled mostly it is not going to and install those updates unless you restart or disable the fast startup.

According to, TrueCrypt users have also reported an issue regarding the encryption. Before shutting down if the drive is mounted, after the restart of the computer you will notice that it is still mounted. This is the issue that the TrueCrypt users have reported. For that the answer is to manually unmount the encrypted drive or disable the fast startup.

Note: Fast startup mostly depends on the hibernation, since most new computers come with the hibernation feature, you can assume that the fast startup is also supported. Older pieces mostly do not support the fast startup so you’re good to go.
