WuInstall - Manage Windows Updates

WuInstall is a command line tool that makes it possible to install Windows Updates on demand. This gives you full control over the patching process. You decide what patches should be applied when and on which machine.

Depending on the System configuration it uses either the internal WSUS server or the external Microsoft Update Server to look for available updates. Afterwards those can be downloaded and installed.

WuInstall was first released in 2009 and today it is used by ten thousands companies all over the world; amongst them are a lot of big enterprises across all industries and public institutions.

Testimonial 3

Many thanks for that – great product!

Testimonial 4

This software is a great tool, and it's command-line based, which I still like best for having some degree of 'control'.

Testimonial 5

Thank you for the updated version of WuInstall Pro. WuInstall is working extremely well for us.

Testimonial 6

Thank you for supporting such an outstanding product!

Testimonil 7

My operations group is looking to automate the WSUS update process and your software is their primary choice.

Testimonial 8

Have been using WuInstall for some time and we have bought the site licence twice now.

Testimonial 9

Often there are a lot of patches already released at the WSUS but not yet installed on the clients. If a security issue arises, only one patch has to be deployed instantly to solve this problem. Until yet we had only the possibility to deploy all released patches or none.

Testimonial 1

We are an NGO trying to train youth in a Zanzibar, a very undeveloped country. Our bandwidth constraints are considerable so I love the cache idea to allow me to distribute updates in my computer lab.

Testimonial 2

It'll keep installing updates and rebooting over and over until all updates are installed. This has been very useful for newly installed Windows XP and Windows 7 computers. I know I could probably setup some slipstream install, but that's more effort than I want to deal with, plus there are too many OEM installs to make that work out for us.
