How to Disable Fast Startup on Windows 10?


Windows 10 users get to use a lot of features aiming to improve user experience with different computer-based functions. The Fast Startup feature is an upgrade from the Windows 8 Fast Boot function. The new version assures a speedier boot-up process but is slightly complex.

Users sometimes find functional defects in the Fast Startup process, which is why it is necessary to disable Fast Startup on Windows 10 when using a new device. In this post, learn how to deactivate this feature with a detailed step-by-step breakdown.

What is the Fast Startup function in Windows 10?

Before learning the steps to disable Fast Startup, knowing what feature is useful is necessary. This default Windows 10 feature allows the PC to go start up after the shutdown phase, similar to the hibernation mode.

While the PC is in the shutdown stage the operating system stores some system information on the disk. Upon switching the computer on, the Windows operating system resumes functionality through the saved system data in the disk instead of restarting the computer fully.

Therefore, the startup time of the system is faster.

Why Deactivate Fast Startup in Windows 10?

For specific reasons, users have to disable Fast Boot Windows 10, more commonly known as “Fast Startup” in the latest version.

  • Allow Windows update installation– The Fast Startup feature can block the steady installation process for new Windows updates. This is because updating a system needs a full OS shutdown to activate. However, during the Fast Startup function, the PC hibernates somewhat. Therefore, the update cannot occur.
  • Allow BIOS/UEFI Settings Access- In some cases, users need to disable Fast Boot Windows 10 or the Fast Startup feature since keeping it active blocks the BIOS/UEFI functioning. So, you need to deactivate this feature to enter the BIOS and make your chances as you need.
  • Manage encrypted disk images better– In case managing the encrypted disk images is proving difficult, you should deactivate this feature on the PC.
  • Dual PC boot up– Some users operate the dual booting function for the PC. To access the available Windows drive on one section while operating on the second, turning on Fast Startup is necessary first.

Sometimes, like checking and updating Windows updates, you can use third-party software like IoBit Software Updater. You should still know how to disable the Fast Startup function when needed. Later, it is possible to reactivate the feature on Windows 10.

Step 5: Tap the option titled “Turn on Fast Startup”, click the tick mark beside it, and then press the Save Changes button.

Situation 3: How to Force-Stop Fast Startup on Windows 10?

How to do this?

Step 1: Click on your Windows button in the Toolbar.

Step 2: Choose the Shut Down option and press the Shift key simultaneously. This causes the Windows OS to go through a hard system shutdown sequence while the Fast Startup function is still active.

You should use the steps to disable the Fast Startup method, as mentioned, and enable it later if needed. Of course, you should practice the steps a few times to get familiar with the sequence over time.
