I find these commands quite helpful — maybe you know them already — if not, here you go:
Microsoft Hotfix Installer (.exe)
setup.exe /t:C: /c
Microsoft Update Standalone Package (.msu)
expand -F:* update.msu C:
cd
expand -F:* update.cab C:
Microsoft Patch File (.msp)
msix patch.msp /out C:
msix.zip
Windows Installer Package (.msi)
msiexec /a setup.msi /qb TARGETDIR=C:
