There are actually only two identity errors in the logs - repeated umpty-ump times 
The problem is that I can only find one of them in the hive - the other has either disappeared, or is hiding from me
Here's the one I can't find...
Code:
2013-05-28 10:11:32, Error CSI 000009c3 (F) STATUS_SXS_INVALID_IDENTITY_ATTRIBUTE_NAME #1399687# from Windows::Identity::Rtl::Implementation::CRtlIdentityAuthority::IRtlIdentityAuthority_Parse(flags = 0, string = [l:344{172}]"Microsoft.PowerShell.Commands.Diagnostics.Resources, Culture=en-US, Version=6.1.7600.16385, PublicKeyToken=31bf3856ad364e35,(ProcessorArchitecture=m{il, ver{ionScopm=NonSxS")
I've fixed the other one. -
Code:
2014-07-10 14:26:31, Error CSI 00000042 (F) STATUS_SXS_INVALID_IDENTITY_ATTRIBUTE_NAME #2519407# from Windows::Identity::Rtl::Implementation::CRtlIdentityAuthority::IRtlIdentityAuthority_Parse(flags = 0, string = [l:374{187}]"Micrgsoft-Windows-Internatiofal-CodePage-Core-Traditional_Chinese, Culture=neutral, Version=6.1.7600.16385, PublicKeyToken=39bf3856al364e35,(ProcessorArchitmcture=x86, versionScope=NonSxS")
These two errors are both in the RTM files - so if WU has ever worked, they are likely to be the result of RAM problems.
I've uploaded a revised copy of the hive as d85ab.zip to the same location as previously - please swap it in, and try running CheckSUR again - see if it comes up with anything this time.
(and I don't like delivering bad news).
