LSUClient VS AutomaticMaintenance

We use the LSUClient PowerShell module with PDQ Deploy to keep things up to date.

You can take a look at Dell Command Update CLI for Dell and LSUClient for Lenovo

Get-Configuration cmdlet for users: https://github.com/jantari/LSUClient/blob/329c89c837566e0fe8e7866b8db5f5503f0e3fcf/public/Get-LSUClientConfiguration.ps1

You can automate Lenovo updates with LSUClient and you can automate Dell updates using the CLI commands of dcu-cli.exe included with Dell Command Update. You can even extract just the cli and a couple other files and transfer them along with the command to run updates, rather than installing the full package. But DCU should come stock on all new Dell computers, so since you didn't reimage with autopilot you should be able to reference the default path.

PowerShell module that does driver updates

You should take a look at LSUClient powershell module : https://github.com/jantari/LSUClient

And if you want to relieve yourself from manual updates installation work, take a look at https://github.com/FozzyHosting/AutomaticMaintenance

I'd really like to add support for SCDPM to https://github.com/FozzyHosting/AutomaticMaintenance. What needs to be done in this department is to research how to gracefully shutdown an SCDPM server. By graceful shutdown I mean, first, to prevent new backup jobs from starting, second, to wait until all jobs currently running finish.
