autoupdate alternate for large corporations!
I'm surprised that I have not seen this alternative. It is possible to setup your own windows update server. When you do this you have the flexibility to select which patches you want to install, and you can also have SMS push the updates to the computers during non peak hours when the users will not be interrupted by it.
From what I've heard the server setup is relatively easy to install and this will fix ALOT of vulnerabilities to a massive amount of computers and quickly. I don't really know of many other ways you can say you've patched 1800 computers in a day!
Just a suggestion!
Have a great day!
