Error source CAPI2 id 513 - Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object

[Win7ine]

Running Windows 8.1 PRO RTM x64 upgraded from Win 8 PRO. Updates to 8.1 as of 17 October installed

Event viewer still shows newly triggered Error(s) CAPI2 event id 513.

I can trigger this error by manually creating a restore point invoking VSS.

The VSS System Writer is listed and is error free.
