We just upgraded to CU3. There is a particular hotfix that is causing us problems (mbs2.microsoft.com/…/kbdisplay.aspx). I was not sure if it is possible to remove just this hotfix without doing a restore.
Please follow the procedure mentioned in the link.

Obviously you want to remove just a hotfix in CU3. I may be wrong -perhaps easiest option may be to find underlying code and comment. Or if you can view the hot fix under Add/remove programs, it can be uninstalled from there.
Thanks for the help. We currently have been commenting out the code as we don’t need its functionality. I will check the add/remove programs (fingers crossed).
