Windows 10: Recurring Certificate Expiration Issue for `taskhostw.exe` Right After Fresh Windows Install

Hello Microsoft Community,I am experiencing a recurring issue with expired certificates for `taskhostw.exe` on my Windows 10 PC. I am just noticing the problem now but can see it started just two days after I performed a fresh installation of Windows, and in that time 1 year I have gotten about a dozen of these errors. I would appreciate any help or guidance on resolving this issue.Problem Description:- Error in Event Viewer: A certificate for taskhostw.exe has expired.

Expired certificate

When trying to update a Nokia N95 I am getting the message "Expired Certificate" after the step Install MMS Sync.



On the computer it is saying installation complete?



Is the installation complete or is the expired certificate a problem?

 

Expired Certificate

Hi,

We understand that you're having an issue with an expired certificate on your Windows 10 PC.

In line with this, have you tried contacting your device manufacturer for an update about the next steps you need to do after the procedure they did on your PC?

To make sure that your PC is secured, kindly run your antivirus software as well as the
System Maintenance troubleshooter. The
System Maintenance troubleshooter will find and clean up unused files and shortcuts, and perform maintenance tasks. Here's how to run the troubleshooter:

• Right-click the Start icon, then select Control Panel.
  
• Choose the Large icons option from the View by drop down list found on the upper-right part of the Control Panel window.
  
• Locate then select Troubleshooting.
  
• Click View all from the left pane.
  
• Locate and click System Maintenance to run the troubleshooter then follow the next steps.
  

We also suggest that you perform a Disk Cleanup in Windows 10 to delete temporary
files.

Let us know the result after following the steps above.
