Windows 10 Home

You may choose between the ‘Full’ and ‘N’ editions. The N editions are an excellent alternative if you are looking to save money. They have exactly the same characteristics as the full version, except that these do not include the default Windows Media Player and Windows DVD Maker programs; you have to install them separately in a package that is included in your purchase.
If you're planning on purchasing an N Edition, it is very likely that you will have to perform a clean installation of Windows, thereby reformatting the computer. You cannot simply activate the current installation on your computer, for that you will need a Full Edition.

To install a 64-bit version of Windows, you need a CPU that's capable of running a 64-bit version of Windows. The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more. In such cases, because a 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, a 64-bit system can be more responsive when running several programs at the same time and switching between them frequently.
