Examples and tips

See available updates:

Get-LSUpdate

Find and install available updates:

$updates = Get-LSUpdate
$updates | Install-LSUpdate -Verbose

Install only packages that can be installed silently and non-interactively:

$updates = Get-LSUpdate | Where-Object { $_.Installer.Unattended }
$updates | Save-LSUpdate -Verbose
$updates | Install-LSUpdate -Verbose

Filtering out non-unattended packages like this is strongly recommended when using this module in MDT, SCCM, PDQ, remote execution via PowerShell Remoting, ssh or any other situation in which you run these commands remotely or as part of an automated process. Packages with installers that are not unattended may force reboots or attempt to start a GUI setup on the machine and, if successful, halt until someone clicks through the dialogs.

To get all available packages:

$updates = Get-LSUpdate -All

By default, Get-LSUpdate only returns "needed" updates. Needed updates are those that are applicable to the system and not yet installed. If you want to retrieve all available packages instead, use Get-LSUpdate -All. To filter out unneeded packages later, just look at the IsApplicable and IsInstalled properties. The default logic is equivalent to: Get-LSUpdate -All | Where-Object { $_.IsApplicable -and -not $_.IsInstalled }

Download drivers for another computer:

Get-LSUpdate -Model 20LS -All | Save-LSUpdate -Path 'C:\20LS_Drivers' -ShowProgress

Using the -Model parameter of Get-LSUpdate you can retrieve packages for another computer model. In this case you almost always want to use -All too so that the packages found are not filtered against your computer and all packages are downloaded.

For further documentation please see the documentation site and run Get-Help -Detailed on the functions in this module.

Misc

• Only Windows 10 and Windows 11 are supported
• This module does not clean up downloaded packages and installers at any point. The default download location is $env:TEMP\LSUPackages - you may delete it yourself
• By default this module reaches out to https://download.lenovo.com and must be able to download .xml, .exe and .inf files from that domain for successful operation. Alternatively, a custom package repository can be used for completely internal or offline operation with the -Repository parameter of Get-LSUpdate. A custom repository can be served over HTTP(S) or just be a filesystem path - local or UNC.
