2018-01 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4058258)

I don’t see this fixlet in BigFix, but it’s available on Windows catalog. Any idea when BigFix will see the fixlet?

Seconded. I do not see anything on the MS websites that would immediately flag this as something IBM would not include, and it is not a superseded update as of the time of this writing.

Unspecified Severity, but we have plenty of those. Applies to Windows 10 1709 (x86 and x64), so nothing special there either.
