Windows Update error 0x800b0100

I am sorry... I have tried this method twice... restarted twice and repeated all the steps.

Unfortunately I still get the windows update error

Some update files aren't signed correctly.

Error code: (0x800b0100)

 

failed to install update Error code: (0x800b0100)

I completed the suggested steps. It does not resolve the issue that i am facing. Windows defender is giving error code 0x800b0100. I cannot get into the store to complete those updates either. Windows update says the device is up to date.

Any other suggestio s?

 

Getting "a digitally signed driver is required"

Hi Thomas,

This error can occur if there is a driver attempting to be installed on the system that was not signed by Microsoft digitally. Driver digital signatures help verify the integrity of the driver packages. To avoid this error, you need to disable the driver
signature enforcement. Follow the steps below:

• Press and hold the Shift key then click Restart button.
• Choose Troubleshoot, then select Advanced options.
  
• Select Startup Settings and click Restart.
  
• Once the computer restarts, you'll see a list of options. Press F7 to select
  Disable driver signature.
• Computer will now restart. Once done, check if the same error will occur.

Let us know the outcome so we can provide further assistance.
