Windows 8.1 64 bits for Windows

Windows 8.1 is the version of Microsoft's operating system between Windows 7 and Windows 10. This file is in ISO format, so it has to be run from a previous version of Windows or installed on a pen drive.

This update from Microsoft is a general improvement of its latest operating system that includes customization options, improved search and applications, the Windows Store, connection to the cloud, and improved security. In addition, it's the only version of Windows to eliminate the drop-down start menu and replace it with a version that takes up the entire screen.
