Architecture	Scope	Type	Silent switches	Source
x64	user	MSI	Custom: ALLUSERS=2 MSIINSTALLPERUSER=1	Default for MSI
x64	machine	MSI	Custom: ALLUSERS=1	Default for MSI

Declared by publisher means the switches come straight from the winget manifest the publisher (or community maintainer) submitted to microsoft/winget-pkgs.
Default for {type} means the manifest doesn't specify silent switches, so the framework's standard switches are shown (e.g. /S for NSIS, /quiet /norestart for MSI).

Frequently asked questions

What is the silent install command for LTspice?

LTspice uses MSI. After downloading the installer, run: msiexec.exe /i LTspice64.msi /quiet /norestart ALLUSERS=2 MSIINSTALLPERUSER=1. The silent install switches are /quiet /norestart.

How do I deploy LTspice via Intune or Configuration Manager?

Use winget for the cleanest path: winget install --id AnalogDevices.LTspice --exact 26.1.1.1 --silent --accept-package-agreements --accept-source-agreements. If winget isn't viable in your environment, package the publisher's installer directly using the silent switches above.
