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.

Regards.
