We've seen a number of topics and questions from users whose Acer model is not listed in the Windows 10 update support list, which I'll link below.
The list that Acer provided is for products that we are committed to helping support running the Windows 10 operating system. Microsoft has also stated that they have worked very hard to make sure that the upgrade for Windows 7 and Windows 8.1 to Windows 10 is available for as many users as possible and that the Windows 10 operating system will work with as many different hardware components as possible.
If your unit is not on this list, you're still eligible for Microsoft's upgrade to Windows 10; however, Acer cannot guarantee full compatibility with all aspects of the PC. Again, Acer is not preventing users from taking advantage of the upgrade offer with Windows 10; however, if your unit is not listed, it's possible that you may run into trouble with specific components of your PC not working well, or at all, with Windows 10. The Acer Community is a great place for users in the second scenario to be able to work together to find sufficient drivers or applications that will support their needs.
