Here's the list of what's being taken away with the Windows 10 upgrade. Many of the items on this list will affect Windows 7 owners only

• Watching DVDs requires separate playback software
  
• Windows 7 desktop gadgets will be removed as part of installing Windows 10.
  
• Windows 10 Home users will have updates from Windows Update automatically available. Windows 10 Pro and Windows 10 Enterprise users will have the ability to defer updates.
  
• Solitaire, Minesweeper, and Hearts Games that come pre-installed on Windows 7 will be removed as part of installing the Windows 10 upgrade. Microsoft has released our version of Solitaire and Minesweeper called the "Microsoft Solitaire Collection" and "Microsoft Minesweeper."
  
• If you have a USB floppy drive, you will need to download the latest driver from Windows Update or from the manufacturer's website.
