How to check if your PC … Well, I just happened to have an old system lying about, so I decided to install Windows 10 on it just to see what would happen. Windows 10 features a more familiar experience for Windows Vista users, such as the Desktop, Taskbar, Start menu and floating application windows. The table below lists Dell Inspiron Laptop computers that have been tested for upgrade to Windows 10 and tested for update to Windows 10 November update.

The 64 bit versions of Windows 7,8 and 8.1 requires a minimum of 2 GB RAM.
