Script to find when IE11 was installed.

I had a patch go out that updated all my computers to Internet Explorer 11 within the past 4 days. I need to isolate these computers from the others in my environment that already had IE11 installed. Is there a script that will help me locate the ones with the recent update?

Here's a PS function that should do the trick; you can pass a bunch of computer names either through the pipeline or as array.
You'll get one object per computer name returned, and if an error occurred, the property Exception will be set to the exception.
Function Get-IEInformation {
[CmdletBinding()]
Param(
	[Parameter(Mandatory=$False, ValueFromPipeline=$True, ValueFromPipelineByPropertyName=$true, Position=0)]
	[string[]]$ComputerName = @($ENV:ComputerName)
)
	Begin {
		$HKLM = [uint32]0x80000002L
		$IePath = "SOFTWARE\Microsoft\Internet Explorer"
	}
	Process {
		$ComputerName |
			ForEach-Object {
				$Result = "" | Select-Object -Property Version, UpdateVersion, InstallDate, ComputerName, Exception
				$Result.ComputerName = $_
				Try {
					$stdRegProv = [wmiclass]"\\$_\root\default:stdRegProv"
					[version]$Result.Version = ($stdRegProv.GetStringValue($HKLM, $IePath, "svcVersion")).sValue
					If ([string]::IsNullOrEmpty($Result.Version)) {
						[version]$Result.Version = ($stdRegProv.GetStringValue($HKLM, $IePath, "Version")).sValue
					} Else {
						[string]$Result.UpdateVersion = ($stdRegProv.GetStringValue($HKLM, $IePath, "svcUpdateVersion")).sValue	## Not necessarily a version string!
					}
					$binInstallDate = ($stdRegProv.GetBinaryValue($HKLM, "$($IePath)\Migration", "IE Installed Date")).uValue
					If ($binInstallDate) {
						$Result.InstallDate = [datetime]::FromFileTime(([BitConverter]::ToUInt64($binInstallDate, 0)))
					}
				} Catch {
					$Result.Exception = $_
				}
				$Result | Write-Output
			}
	}
	End {
	}
}
