You can modify the objects to list any number of past History of updated events.

# Convert Wua History ResultCode to a Name # 0, and 5 are not used for history # See https://msdn.microsoft.com/en-us/library/windows/desktop/aa387095(v=vs.85).aspx

function Convert-WuaResultCodeToName
{
param( [Parameter(Mandatory=$true)]
[int] $ResultCode
)
$Result = $ResultCode
switch($ResultCode)
{
2
{
$Result = "Succeeded"
}
3
{
$Result = "Succeeded With Errors"
}
4
{
$Result = "Failed"
}
}
return $Result
}
function Get-WuaHistory
{
# Get a WUA Session
$session = (New-Object -ComObject 'Microsoft.Update.Session')
# Query the latest 1000 History starting with the first recordp
$history = $session.QueryHistory("",0,50) | ForEach-Object {
$Result = Convert-WuaResultCodeToName -ResultCode $_.ResultCode
# Make the properties hidden in com properties visible.
$_ | Add-Member -MemberType NoteProperty -Value $Result -Name Result
$Product = $_.Categories | Where-Object {$_.Type -eq 'Product'} | Select-Object -First 1 -ExpandProperty Name
$_ | Add-Member -MemberType NoteProperty -Value $_.UpdateIdentity.UpdateId -Name UpdateId
$_ | Add-Member -MemberType NoteProperty -Value $_.UpdateIdentity.RevisionNumber -Name RevisionNumber
$_ | Add-Member -MemberType NoteProperty -Value $Product -Name Product -PassThru
Write-Output $_
}
#Remove null records and only return the fields we want
$history |
Where-Object {![String]::IsNullOrWhiteSpace($_.title)} |
Select-Object Result, Date, Title, SupportUrl, Product, UpdateId, RevisionNumber
}

Then now type the following command to get the updates history events with result date, update title, support URL, and update ID.
