Download and Install WuInstall

Download WuInstall directly from wuinstall.com. A fully functional 30-day trial is available so you can evaluate WuInstall against your infrastructure before committing. After the trial, licenses can be purchased online by credit card or via purchase order — see the the website for pricing details.

Setup is minimal by design. Download the ZIP, extract it, and you're done — the only file you need is WuInstall.exe. No installer, no dependencies on external DLLs, .NET frameworks, or PowerShell libraries. This makes it a true portable executable you can call from any location, which is a significant advantage over PowerShell-based solutions or other third-party tools that require runtime dependencies.

Every WuInstall call must include exactly one of these three flags. Additional options can be combined freely alongside them.
