"gwmi win32_quickfixengineering" but only need InstalledOn date - windows

Question

gwmi win32_quickfixengineering InstalledOn |sort installedon -desc | select -First 1
I've tried but that gives me an odd formatting. I simply need to return the installedOn date and maybe the name.
i'm trying to find the most recently installed patch on a system and get that date value.
I've also tried.
gwmi win32_quickfixengineering |sort installedon -desc | select -First 1
better formatting but still too much information.

Answer 1

To get just the InstalledOn properties, you can use the -ExpandProperty option as below.
GWMI win32_quickfixengineering | sort -Descending InstalledOn `
| Select -ExpandProperty InstalledOn -First 1
Otherwise you can do something like the below to get a brief overview of the installed KBs.
GWMI win32_quickfixengineering | Select HotFixID, InstalledOn, Caption
Info:
Select -ExpandProperty
Get-HotFix / win32_quickfixengineering

Answer 2

The easiest way to get specific information you want is the following:
Lets say you need a name of a service for a command:
$Service = Get-Service Spooler
That command would retrieve more information than just the name, but to get the only name, you can type:
$Service.name
That will return only that value from the saved variable.
So in your case you could do:
(Here you save all the information into a variable)
$Quickfix = gwmi win32_quickfixengineering | sort installedon -desc | select -First 1
(You can then use that variable to return specific information from that variable)
Then use: $Quickfix.InstalledOn
That will return you JUST the date.
Then you could do something like:
Write-Output "Latest update was $($Quickfix.HotFixID) installed on: $($Quickfix.InstalledOn)"
That will give you an output of the KB and the date installed. You can of course edit the text, it was just an example.
