To perform a compatibility check, please do the following:
  • Find the Get Windows 10 app icon in the notification tray at the bottom-right corner of your screen (it's the white Windows logo as shown in the image below).
       
  • Right-click on it and select "Check your upgrade status."
  • Then, in the screen that appears, click the icon with the three horizontal lines in the upper-left corner. From the menu that drops down, click "Check your PC."
The app will bring up an overall "yea" or "nay" on installing Windows 10, and then list some items on the computer that might not be fully compatible. There might be things it misses, but it should give you a general idea of whether or not an upgrade is going to be smooth for you.
