Yes, Windows 10 is faster from Windows 7. If you have the proper hardware and drivers available from your system manufacturers, you can use it.
Upgrade to Windows 10 and see the changes. There are many options like Cortana, multi desktop and easy switch between tab…it will help you to make your work easier.
System startup and shut down process is also easy and takes only few seconds to start machine. But to work properly, you must have enough RAM on the system.
