Empty start menu
MS's latest update KB 4467702 failed twice to install. After the first failure I got an empty start menu. I changed WBs on version 10.65 several times with the same result. On the third try the install happened and I rebooted yet the problem persists. I don't know what happened so I'm running an sfc scan now. Also look at the settings window. Notice the frame is only partially applied. WB tried to skin it but it reverted back to flat buttfugly.
