Does the “group policy service failed the sign-in” error message keep popping up? You’re most likely dealing with a corrupted file. Other issues can cause it too, like having fast start-up enabled, and an outdated Windows version.

If you’d like an ultimate look at the error message, along with all the fixes available, read ahead.

Why Does the “Group Policy Service Failed To Sign In” Error Appear?

The error message pops up when the Group Policy fails to respond to Winlogon. Most of the time, a corrupted file causes this. However, an outdated operating system and isolated glitches can be responsible too. There are 5 easy fixes to this error.

Solution 1: Edit Registry Via an Administrator Account

Editing your computer’s registry can help. Although this sounds like a lot of work, it’s actually not.

Here’s what you do:

  • Press Windows key + R (the Run program should launch)
  • Run the Regedit command
  • Search for the following registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\gpsvc
  • Find this key afterward – HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SVCHOST
  • There should be a GPSvcGroup-string. Right click the panel and create a value with the same name, and then assign it to GPSvc if there isn’t
  • Open the new folder that you made
  • Right click the panel again
  • You will have to create 2 DWORD values. AuthenticationCapabilities, which should have a value of 0x00003020, and ColnitializeSecurityParam, which should have a value of 1.
  • Reboot your PC afterward

Solution 2: Reset Google Chrome

An isolated glitch could be causing apps that don’t require admin permissions to act up. Resetting these applications will do the job. But there are probably many of them on your computer, so you might not know where to start.

We recommend Google Chrome:

  • Press and hold the Windows Key + R
  • Run the appwiz.cpl command
  • Click on the Program & Features menu
  • Search for Google Chrome
  • Uninstall the browser

Solution 3: Turn off fast startup

Do you have the fast start-up feature running? Although it can be useful, it can cause your PC to slow down when shutting down. Error messages like the one you’re facing can pop-up because of this.

Here’s how you fix this:

  • Click the Start button
  • Tap on Settings
  • Select the Power and Sleep menu
  • Click on Additional Power Settings
  • Tap on “Choose What the Power Buttons Do”
  • Scroll down
  • Disable the Turn on Fast Startup feature
  • Save the changes that you made

For added measure, we recommend restarting your computer. The issue should be history now.

Solution 4: Restart Group Policy Service and Reset Winsock

Restart the Group Policy app if you’re still having trouble. Just keep in mind that this is a bit of work. We’ve divided what to do into 2 parts to make it easier.

Part 1:

  • Press the Windows key + R (the Run app should launch)
  • Type in the ‘Services’ command
  • Scroll through until you find the Group Policy Client
  • Right click its properties
  • Toggle the Automatic feature on

Part 2:

  • Click on the Start button
  • Click on Apply
  • Tap the OK prompt
  • Open Power Shell
  • Type in the following command – .netsh winsock reset
  • Run the ‘Exit’ command afterward

Solution 5: Update Windows

When was the last time you updated Windows? You might be dealing with a bug if it’s been a while. Downloading the latest OS version should sort this.

All you do is:

  • Click on the Start button
  • Enter the Update command
  • Wait for the Windows Update window to appear
  • You should see an update prompt
  • Click Ok
  • Install the firmware file available

Try not to disconnect mid-way. Your PC can end up on a boot-loop otherwise. Hopefully the Group Policy error will be gone now.

Fixing the Group Policy Service Failed to Sign in Issue

The error message pops up when the Group Policy acts up and stops responding to the call-upon system that Winlogon initiates. This can happen due to various reasons, but isolated glitches, bugs, and corrupted files are the major culprits.

One of the most popular fixes is editing your PC’s registry. Hopefully, you found everything that was discussed useful. What do you think?
