You want to create a custom OS? Don’t do it!

More than one and a half year ago I have been working on a project — I used to call these kind of hackjobs “Custom OS”, but that term doesn’t fit very well if you ask me (actually it was a OS customization) — called Codename Sylvester.

How to extract msu/msp/msi/exe files from the command line

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:* C:<target_dir> Microsoft Patch File (.msp) msix patch.msp /out C:<target_dir> Windows Installer Package (.msi) msiexec /a setup.msi /qb TARGETDIR=C:<target_dir>
