Here is a really quick way of checking if a particular Windows Update patch has been installed using PowerShell.

And it’s much easier than searching through the Windows Update History!

The PowerShell Cmdlet we’re going to be using is Get-HotFix.

Open a PowerShell window and type Get-Hotfix

If you are looking for a particlar KB article use the following: Get-Hotfix KB3185911

That’s great for the local computer but what if you need to check on a remote computer?

First let’s look at the help, type Get-Help Get-Hotfix

So we can see there us a -ComputerName String parameter and -Credential, so let try the following:

Get-Hotfix KB3185911 -ComputerName MGMT, HV01 -Credential domain\username

You’ll be prompted for the user account password

And then you will get a similar output to below.
