Windows 10: receiving event id 18, 19 and error with thumbprint expired

For the past couple of weeks I've been getting the following warning in the event log.Certificate for local system with Thumbprint e2 55 21 d7 49 13 03 1a 20 51 39 6c 0a f4 fd 51 20 ed 00 c9 is about to expire or already expired.In addition, sometimes 1-2 times a day my game crashes.It also wrote me this if it helps:The Windows Security Center Service was unable to load instances of AntiVirusProduct from datastore.The Windows Security Center Service was unable to load instances of FirewallProduct from datastore.Any ideas anyone ?

:)

 

Event 64 Error Message about expired thumbprint certificate

I just started getting the message attached below:



I read the older threads, but things seem to have changed. The Microsoft site https://docs.microsoft.com/en-us/pre...ectedfrom=MSDN says it hasn't updated the directions & my console root doesn't have a "personal" option. I don't want to do something without knowing what to do.

I did run Powershell to get more information, but I'm afraid I don't understand it. It said:
Subject : CN=F90019BD9C90462DIssuer : CN=XBL Client IPsec Issuing CAThumbprint : 8A081123B949018CEF2B6FCC8CE0F2FF0D1DFEF3FriendlyName :NotBefore : 9/22/2019 4:25:51 PMNotAfter : 9/23/2019 4:25:51 PMExtensions : {System.Security.Cryptography.Oid, System.Security.Cryptography.Oid, System.Security.Cryptography.Oid}

When I ran another PS command that was mentioned in another thread, it returned:
PS C:\Users\Phil> dir cert:\LocalMachine\my | Where-Object { $_.HasPrivateKey } | Foreach-Object { write-host $_.thumbprint - $_.subject }8C3603ADD9679756B426504FCCA4F03659DC83AA - CN=NVIDIA GameStream Server8A081123B949018CEF2B6FCC8CE0F2FF0D1DFEF3 - CN=F90019BD9C90462D

Can anyone tell me, step by step, how to track down & renew the thumbprint certificate?
Thank you in advance!

 

Event ID 19 WHEA-Logger

I just received two Event ID 19 WHEA-Logger's tonight, "Reported by component: Processor Core"

Google led me to a Ten forums thread that seems to indicate this Meltdown and Spectre patch related. Has anyone else had these or know anything more about it?
