Windows Update 80092026 plus Certificate Crypto Operation Failed
in Microsoft on Certificates, Windows-update
Ok, two separate issues but here, but fixed the same way. First up is Windows Update reporting:
Windows could not search for new updates Error(s) found: Code 80092026
Then un-related to Windows Update, a code-signing certificate issued from an internal certificate authority, reporting:
The cryptographic operation failed due to a local security option setting
Both issues fixed by deleting the following registry key:
HKLM\SOFTWARE\Policies\Microsoft\SystemCertificates\TrustedPublisher\Safer
I’m unsure of what the cause is, presumably it’s got something to do with the way Windows Vista handles certificate revocation and status checking.
