What exactly does KB2952664 do?

@MD Tech

Just in case you have not noticed the whole 25 pages of this thread is largely devoted to rants against Microsoft. Very little space is devoted to rational discussion. I guess you think dissent equates to rant.

Guys,

Just ignore Cornell. His icon says he is a "Windows 10 Launch Expert." He's drinking the kool-aid; let him rant and ramble, then just ignore him.

I have NEVER participated in the Customer Experience Improvement Program and KB2952664 is still following me around like a puppy looking for table scraps, on all of my computers. If it behaves like nagware it IS nagware.

Some folks simply cannot see the forest for the trees. while they may have my sympathy, they don't have my trust.

BTW, I love the "digital dust" reference. Nice going, Thrash.  :)

Some updates I do not bother to hide this is one of them since it is reissued about every month.

I just leave it in the Optional section to collect digital dust.

This update performs diagnostics on the Windows systems that participate in the Windows Customer Experience Improvement Program.

If you are not in the Windows Customer Experience Improvement Program the update does not or should not apply!

Yet it still appears in my available updates every time it is re-issued, despite not participating in the Windows Customer Experience Improvement Program, and despite having hidden it every time it appears. And if you ask around, you will find that it does the same for others not in the CEIP.

You seem to be suggesting that for those not in the CEIP, the update will have no effect, despite folks reporting otherwise. Either way, since I don't need it, I will continue to hide it, along with just about everything else that is not specifically (and exclusively) security related.

Caveat emptor.

If you are not in the Windows Customer Experience Improvement Program the update does not or should not apply!

Gerry,

Legacy2000 stated this:

I am not participating in the Windows Customer Experience Improvement Program and have disabled all tasks, services, and processes related to it, as well as anything else from Microsoft that is telemetry-related. I still get KB2952664 in available updates every time it is re-released, as does everyone else (whether or not it has been previously hidden). It seems, then, that what is not relevant to receiving this update is participation in the CEIP.

I too am not participating in the Customer Experience Improvement Program and have disabled all associated tasks and settings. I have also hidden KB2952664 each time it has been reissued.

So, why does Microsoft continue to unhide KB2952664 (and place it into the list of available updates) if I have clearly disabled all settings for the Customer Experience Improvement Program?

As you said, KB2952664 should not apply (because I have opted out of the Customer Experience Improvement Program) ... but Microsoft keeps unhiding this update and giving it back to me. Why are they doing that (if I have opted out of the Customer Experience Improvement Program)?

Perhaps Microsoft keeps pushing KB2952664 (even to those who have opted out of the Customer Experience Improvement Program) because KB2952664 does more than "perform diagnostics on the Windows systems that participate in the Windows Customer Experience Improvement Program."
