Which feature significantly changed from Windows 7 to Windows 10, easing the operating system installation process?

The feature that significantly changed from Windows 7 to Windows 10, easing the operating system installation process, is driver detection. In Windows 10, the driver detection capability has improved considerably, making it easier for the operating system to identify and install compatible drivers during or soon after the installation process. This reduces the need for users to search for and manually install individual drivers, enhancing the overall user experience and streamlining the installation.

With better driver detection, Windows 10 can automatically update and install many drivers directly from the Microsoft servers, ensuring that the system is optimized and fully functional sooner after installation. This was a notable enhancement over Windows 7, where users often faced challenges with driver compatibility and had to undertake more manual intervention.

While the other features mentioned—Metro interface, account control, and PXE installation—may have been updated or modified in their functions in Windows 10, they do not primarily focus on simplifying the installation process in the same fundamental way that improved driver detection does.
