I've been tasked to automate a process of uninstalling few MS kb's that's causing some of the other applications to fail. I wanted to get the blessings from my fellow packagers to go with the uninstall or if it's not a good idea of uninstalling them than please let me know. Any thoughts on this will be appreciated.

KBs are installed for a reason so you'd have to have some pretty powerful justification for removing them.

What is the nature of the application failure? Can you not work round it by some other means?

BTW, what are your patching/Desktop people doing, if not regression-testing MS updates?!? Jeez...

We don't really have a team here to perform the rigorous testing on MS patches we only have a testing pilot group & if the updates not breaking anything it's consider a go from a deployment stand point.

We have an in-house browser based application which breaks after installing these patches & if you uninstall them everything seems to work fine. It's only a small group of Users i guess uninstalling those patches should not cause any other issues?

Take a look at the registry key HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall

There should be an UninstallString which you can use to uninstall your Hotfix.

But as VBScap said, it's much more recommended to resolve the problem by figuring out whats from with your browser application

Most have a rollback, but some don't. You would need to look at the release notes for that KB and it should provide uninstall instructions. It will also tell you exactly what was affected by applying the patch (files/registry/setting/etc) and known issues so you will have an idea what broke and what is broken when the patch is removed. This is what you should be doing before patching and after a problem is found.

Having said that, you can also find the spuninst.exe in the patch folder. It has to be exucuted from that specific directory to work.
C:\WINDOWS\$NtUninstallKB#######$\spuninst

CAUTION!!!!! This can do far more damage to the system than a broken web app so test like crazy before you touch a live system. Maybe even clone a live system and test on that.
