Refreshing local Windows Server Update Services (WSUS) settings and deleting the Windows Update cache are effective steps in resolving issues with Windows 10 not installing updates.

The first step in installing an operating system on a new computer is Setting the boot order (Option A). This ensures that the computer can boot from the installation media (USB, DVD, etc.).

* Entering the product key (Option C) and Selecting the filesystem (Option D) are subsequent steps during the installation process.
