Windows 8
Upgrading to Windows 8.1
Software compatibility
In order for software to work, it has to be compatible with the operating system. Therefore, you may not be able to use all of your existing software if you switch to a different operating system. Before you upgrade to Windows 8, ask yourself if there is any software on your computer that you can't do without—and then do some research to find out if it is compatible.
If you are upgrading from Windows 7 or Vista, most of your apps should still work. However, if you're using an older version like Windows XP, there's a good chance that some of your apps will not be compatible with Windows 8. A simple Google search will often be enough to tell if an app will be compatible in Windows 8.
