Constant Certificate Errors (Home Premium)
I noticed that in event viewer I have been getting the following error for taskhostw.exe persistently, beginning just 2 days after I installed Windows on this PC. The error says:
"A certificate has expired. Please refer to the "Details" section for more information." Each of these errors has a unique thumbprint but share the same the same certificate name (F900DF260332AC7F) and the same EKUs and OIDs, which are found in the following screenshot:
According to the timestamps of the events, the first error was 2 days after I installed Windows on this PC. There have been 28 of them in the ~1 year I've had Windows on this PC. Sometimes they happen a day or 2 apart, but I haven't been able to correlate it to anything specific.
--------------------------
In trying to fix this issue I saw I also get constant CAPI2 certificate errors in event viewer too. For example:
I even got one for tenforums.com while writing this post:
If it was just one certificate issue I wouldn't notice or care, but I get these constantly for various Windows processes including Defender and 3rd party programs.
Steps I've tried:
-Made sure Windows is up to date.
-Ran sfc /scannow, DISM CheckHealth, ScanHealth, and RestoreHealth commands.
-I ran a powershell script to search all stores for the thumbprint 99aec08668bd760c46f5b5aadff4f0d5c565f470 (the most recently expired taskhostw.exe thumbprint from the first 2 screenshots) but it found no results.
-(For the CAPI2 errors) I reset my cryptographic services database via:
net stop cryptsvc
ren %systemroot%\System32\catroot2 catroot2.old
net start cryptsvc
-I synced my clock (sometimes when I turn on my pc the time is off by 3 hours) and restarted windows time service
-I restarted the cryptographic service
I've never messed with certificates before so I've had to familiarize myself with the MMC, and it might take me a bit of time to try out any suggestions. With that said does anyone have any ideas how to fix the certificate errors and find out what the mystery certificate that keeps periodically expiring is?
My current version of Windows is: Windows 10 Home 22H2 19045.4412
Thank you!
