CO-Release Build 21364 to Dev Channel + KB5003397 + KB5003402 to .1011

364 took it, the Definition Update without any error or Retry.  Had no problem, at all, successful & of course, listed.

I, also, hit this on 20H2.  I used PowerShell.  Now, says it's Up to Date, but it is not listed in Update History.

I'll get back shortly regarding this in 364... (y'all have me curious, now)

If if is not done with W.U. it does not show up in the History. When I update directly from defender it shows  here, but not on W.U. history. History will update next time W.U. finds another defender update.

Hi Johnny, 

I'm sure the problem was on their end.

Try the update from defender directly, it worked fine for me and then the next update worked normally with W.U.

Same on all 20H2 machines.
