A help desk technician is preparing to upgrade the company's desktop OS from Windows 7...

The Update Assistant tool is designed to perform an in-place upgrade to Windows 10 that preserves user applications, data, and settings while automating much of the upgrade process. A clean install (A) wipes all data and applications, which is more time-consuming and risky. The Windows Update tool (B) is typically for updating the current OS version, not a major version upgrade like Windows 7 to 10. The "Refresh this PC" option (C) reinstalls Windows but removes applications, so it doesn’t preserve apps. Core 2 operating system objectives identify the Update Assistant as the preferred method to minimize effort and preserve user data during major upgrades.
