I'd like to uninstall some Windows updates that seem to be causing trouble with Outlooks search function. The updates were installed yesterday, so my approach would be something like "List all updates with deployment date xx-xx-xxxx yy:yy:yy" and loop through the result with an uninstall command. So far the theoretical part.

When I try to list the updates in commandline or PowerShell I receive incomplete results (at least when comparing them to the control panel): Screenshot from control panel

I've found multiple ways to list the updates via Powershell or WMI query, but none of them returns valid results:

wmic qfe list (the most prominent way to do it, apparently):

PS C:\Windows\system32> wmic qfe list

The result of both commands is based on the same WMI query, so I didn't really expect different results here... Some other Powershell Cmdlets I tried provided the same output (Get-WindowsUpdate from Powershell Gallery - "Install-Module -Name PSWindowsUpdate", Get-Hotfix)

I than tried Get-MSIPatchInfo from https://github.com/heaths/psmsi/wiki/Get-MSIPatchInfo - which listed quite a few patches and corresponds with my list in the control panel. Details to the patches reveal the PatchCode, ProductCode, State, Displayname and a boolean field if the Patch is uninstallable, bot no install date.

Am I right to assume, only the latest patches are listed here and can be uninstalled with something like:

Get-MSIPatchInfo | Where-Object {$_.DisplayName -like "*office*"} | Uninstall-MSIPatch -Force

Look at the Windows Update Powershell Module install-module pswindowsupdate since that might be a straightforward way to get this done

$history = Get-WUHistory -MaxDate (Get-Date).AddDays(-14)

or however many days you need to go one day beyond the date you want. Pop the variable to see if you have the updates you're looking for write-host $history

Filter that by the date you're looking for

$filterHistory = $history |Where-Object{$_.Date.tostring('yyyy-MM-dd') -like ((get-date).adddays(-13)).tostring('yyyy-MM-dd') -and $_.KB}

The last -and $_.KB is to ensure you're only getting objects with KBArticleIDs

Then feed that to the Remove-WindowsUpdate

$filterHistory | Remove-WindowsUpdate -KBArticleID $_.KB -whatif

remove that -whatif if you're satisfied with what it will do.
