Windows 10 received an update last night and now everything is fucked up. First of all, the start button no longer responds to left-clicking, nor to the start button. Right-clicking on it will bring up a menu, but it doesn't look nice like what the earlier start menu. Secondly, it doesn't display my open apps on the bottom taskbar; instead, they are consolidated into a single task view icon which opens up thumbnails of my open windows when I click on it. That's more work than just clicking on the icon on the taskbar to view the corresponding window. Also, the date and time is not visible on the right hand corner anymore. I can hover my cursor over that area and a text box will appear showing that info, but again, that's more work. I trying to figure out if there's a way I can reverse these unwanted changes.
