Hi Dinh,

Thank you for posting in Microsoft Community.

I understand your concern and frustration you have been through. I will be glad to assist you.

1. Have you installed all pending updates?

I suggest you to install any pending Windows updates on the pc to check if that helps. Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.

This issue might occur if your computer is not up to date with Windows updates. Also if there are app corrupted.

Follow the Methods below.

Method 1: Run app troubleshooter

Refer:

If this doesn’t resolve the issue then try next method.

Method 2: Refer the link suggested by Rohit Siddegowda on October 9, 2015.

Thanks

Thanks. I tried the renewal option but I got this error:



What is the XBL Client IPSec Issuing CA certificate for and do I need to do anything to update it? I would delete it if I knew what it's for but the certificate properties shows You have a private key that corresponds to this certificate. I don't want to delete it unless I'm sure what the certificate is for.

I also discovered the certificate warning is directly correlated with and preceded by a fraction of a second with this warning:



Knowing what this warning is for may shed some light on the issue.

 

Event ID 219 task(212).

Event ID 219 Windows Kernel PNP - Microsoft Community

 

I exported / backed up the outdated certificate then deleted the original certificate. The warning is now gone and I can always reinstate the certificate if required. I've stopped the Event ID 219 error which happened at the same time by disabling the Portable Device Enumerator Service.
