The Microsoft Update Health Tools appears to be an optional add-on which helps Windows do updates. Beyond that all of my searching has come up with vagueness. But Microsoft recommends it and often installs it without informing us, so probably it helps fairly often.

Microsoft Update Health Tools comes in KB4023057. To install KB4023057, we can use PSWindowsUpdate:

Here’s a complete run-anywhere command paste for preparing to use the module (administrative shell only please):

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Set-Executionpolicy RemoteSigned -Scope Process -Force
Install-PackageProvider -Name NuGet -Force -ErrorAction 'SilentlyContinue' > $null
Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
If (Get-InstalledModule -Name PsWindowsUpdate -ErrorAction 'SilentlyContinue') {
	Update-Module -Name PSWindowsUpdate -Force
} Else {
	Install-Module -Name PSWindowsUpdate -Force
}
Import-Module PSWindowsUpdate

and the command for just KB4023057:

Install-WindowsUpdate -KBArticleID KB4023057

PSWindowsUpdate is a very interesting module all by itself, it can do lots of things, e.g., install all updates available from Microsoft. Another nice function is:

Reset-WUComponents

To get a full list of functions:

Get-Command -Module PSWindowsUpdate

Get-Help works for all of them.

One can install all updates available from Microsoft, though this can be dangerous, there are huge ones and drivers and BIOS too. So this simple command won’t be here :-)

To just see the list of available updates:

Get-WindowsUpdate

To install all available updates except one KB:

Install-WindowsUpdate -AcceptAll -NotKBArticleID KB000000

and except a list (here of two) KBs:

Install-WindowsUpdate -AcceptAll -NotKBArticleID "KB000000,KB000001"

where KB000000 is a KB to be excepted. There’s also -NotCategory and -NotTitle for items without KB articles.
