Latest Windows 10 20H1 Insider Build Introduces A New Shutdown Bug, Here’S How You Can Fix It

Microsoft rolled out a new Windows 10 Insider Preview build for Fast ring Insiders. The Windows 10 Build 18999.1 belongs to the 20H1 branch.

The Redmond giant didn’t roll out any new features in this build. However, the build brings some changes for Fast Ring Insiders. Windows 10 Your Phone app now allows you to receive phone calls. Additionally, you can resize and move Cortana as per your requirements.

The Windows insiders started downloading the update soon after its release. Notably, there are multiple reports on Reddit (1,2) and official Microsoft Community forums that the update breaks the shutdown process.

“Help! since the 18999.1 update my pc won’t wake from sleep and won’t fully shut down. I keep having to press and hold the power button.”

Another user who installed the recent Insider Build confirmed a similar problem.

“This same exact thing is happening to me. I have fastboot and hibernation turned off, no dynamic lock, actually turned bt off along with any running programs and I tried going back to the stock drivers, etc.”

Apparently, some people installed the update with the Fast Startup feature enabled on their Windows 10 PCs. The update created problems on such systems, but those who didn’t enable this option reported that they are unable to shut down or restart their PCs as well.

Fix Shutdown Issues on Windows 10

Microsoft has already acknowledged this problem and confirmed that the company is investigating the reports.

“We’re investigating reports that some devices are getting stuck during shutdown or restart.”

For now, we have listed some quick workarounds that you can use to fix this issue.

Disable Fast Startup

The Fast Startup option in Windows 10 restricts the operating system from performing a regular shutdown. Basically, the feature hibernates your Windows kernel that eventually turns off the display before shutting down your PC. In other words, Fast Startup is just a new word for hibernation. Follow the below-mentioned steps to disable Fast Startup on your PC.

  1. Open the Run dialog by pressing the Windows Key + R keys.
  2. Type powercfg.cpl and hit the Enter key to open the power options.
  3. Go to the left pane and select Choose what the power buttons do.
  4. Under the Shutdown settings section, uncheck the Turn on fast startup option.
  5. Click Change settings that are currently unavailable if the Shutdown settings options are greyed out.
  6. You can then apply the changes by clicking the Save changes button.

If the feature is not enabled on your system, move to the next solution.

Run System File Checker Tool

Many Windows 10 users confirmed that running the sfc /scannow command resolved the problem. The System file checker tool scans all the protected system files on your system and replaces the corrupted files.

Shutdown Without Using The Power Button

You can try using the old school word around to shut down your system. Simply press the Alt & F4 keys in order to shut down your system. Moreover, if the above-mentioned solution does not work for you, you can try using the command prompt:

  1. Type cmd.exe in the Windows 10 search box.
  2. Look for cmd.exe option from the list of search results. Right-click on it and select Run as administrator.
  3. Once the cmd window opens on your screen type shutdown /s and hit the Enter key.

Your system might take a few seconds to shut down your computer.
