Start menu dead, Explorer frozen, .NET apps broken

September’s update managed to break the three things you need most: Start menu, File Explorer, and Search. All three became completely unresponsive. As an encore, the update silently disabled .NET 3.5 Framework, breaking every legacy business application that depended on it. SQL applications crashed on both client and server. Gamers got TDR errors and blue screens. The update contained “24 fixes” according to the changelog — it just also contained about 24 new bugs to go with them.
