More information for advanced users
This issue occurs when the Managed Object Format (MOF) file that
is associated with Security Center (Wscenter.mof) has been modified in a way
that makes it incompatible with the update process.
By performing the
procedure in the "Resolution" section, you use the MOF compiler, Mofcomp.exe,
to register the original MOF file. (Mofcomp.exe is included with Windows.) The
Windows Vista SP1 update replaces the original MOF file
registration, and this behavior causes the problem that is described in the "Symptoms" section.
After you restore the original MOF file registration, install the update
again.
