How to determine the date and time of most recent successful Windows Update run on Windows Server 2016

windows-registrywindows-server-2016windows-update

It appears that Microsoft removed this registry key in Server 2016.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install

Does anyone know of an equivalent registry key that has the last Windows Update install success date/time? Or perhaps a different method of querying this value?

I've spent hours googling, but have found nothing. Closest registry key I can find is:

HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

However, it has no key for last successful install date/time.

Tested and this guy's find did work:

Get-WmiObject -Class win32_reliabilityRecords -filter "sourcename = 'Microsoft-
Windows-WindowsUpdateClient'" -ErrorAction SilentlyContinue |
select @{LABEL = "date";EXPRESSION = {$_.ConvertToDateTime($_.timegenerated)}}, 
@{LABEL = 'Update';EXPRESSION = {$_.message}} |
FT -AutoSize -Wrap

Gives you a nice summary:

date                 Update
----                 ------
8/18/2017 8:39:51 AM Installation Successful: Windows successfully installed 
the following update: 2017-08 Cumulative Update for Windows Server 2016 for 
x64-based Systems (KB4034658)
...

Of course you could just take out the description & titles if you just want the date itself.
