I find these commands quite helpful — maybe you know them already — if not, here you go:

Microsoft Hotfix Installer (.exe)

setup.exe /t:C:\<target_dir>\ /c

Microsoft Update Standalone Package (.msu)

expand -F:* update.msu C:\<target_dir>
cd <target_dir>
expand -F:* update.cab C:\<target_dir>

Microsoft Patch File (.msp)

msix patch.msp /out C:\<target_dir>
msix.zip

Windows Installer Package (.msi)

msiexec /a setup.msi /qb TARGETDIR=C:\<target_dir>
