The image is a screenshot of a pop-up window on a computer screen. The window is titled "Ready to install" and it appears to be a tutorial or guide on how to install Windows 10 Enterprise. 

At the top of the window, there is a message that reads "You won't be able to use your PC while Windows 10 installs. Save and close your files before you begin." Below the message, there are two options - "Install Windows Enterprise" and "Keep personal files and apps". The "Change what to keep" option is highlighted, indicating that the user is in the process of installing the Windows 10 operating system.

On the right side of the screen, there has a blue "Back" button and a "Install" button, which may be used to proceed to the next step in the installation process. On the left side, it seems like the user has already completed the installation and is now ready to proceed with the task.
