A technician is setting up a newly built computer. Which of the following is the FASTEST way for the technician to install Windows 10?

Factory reset restores an existing system to its original state, which is not applicable to a newly built computer without an OS.

System Restore reverts system files to a previous point in time, requiring an existing OS and restore points, and does not install a new OS.

In-place upgrade updates an existing operating system to a newer version or edition, which is not relevant for a newly built computer without an OS.

An unattended installation uses an answer file (unattend.xml) to automate all setup steps, including partitioning, user accounts, and driver installation, significantly reducing the time and manual effort required for a fresh OS install. This method is ideal for deploying Windows 10 rapidly on multiple new machines or a single new machine where speed is paramount.
