Have installed this update 3 times and have been through all of the suggested fixes for other problems and still have this problem where the Windows search bar doesn't work. I start to type a search term, and the window closes. If yo are not going to fix this problem, please stop pushing the update on me. Every 7 days ( the pause period for updates ) it takes me about an hour to logon on. It first does the update, then I have top uninstall it.
