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

Solution 1:

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.

Solution 2:

I use:

    Invoke-Command -ComputerName  $ComputerName -ScriptBlock { (New-Object -com "Microsoft.Update.AutoUpdate").Results.LastInstallationSuccessDate} -ErrorAction SilentlyContinue

Be aware that the time is in UTC.
