We are using SaaS/VSA:
Patch Management - Patch Policy - Approval by Policy
We push all patches through Kaseya, denying Windows Auto-update everywhere.
Occasionally we get what appear to be two *almost-identical-but-not-quite-by-a-few-KB* patches under the same KB number. These aren't 32-bit vs. 64-bit or Internet-only vs. not: these are identical in every way but for a slight size difference. Even the dates are the same, and they are minutes apart in time.
See screen shots, above (these are for KB4462923).
Has anyone seen these? Should I select both? What will happen if I do that? Or should I throw a dart at one at random and pick that? What is the downside of doing that?
The update identifiers and the Location IDs are different as well ... So they must be for slightly different versions of Win 7, perhaps one is for Win 7 with a specific service pack and the other for without?
Gonna step out on a limb here and say, based on the Update Identifier, one is a generic update and the other is region/LOCALE specific, otherwise they are identical. The "1033" is the standard locale code for "US English". "200" doesn't show up in the Microsoft Locale chart that I checked, so guessing here that it's region-agnostic. The small difference in region-specific data would nicely account for the 30KB difference in size.
My experience with updates has been that the more-specific update will usually be applied. If you want to sleep better at night, download both to a test system, deploy the "1033" version first, then the other and see if it rejects the second install as "already applied".
Again - just a somewhat educated guess.
