A technician is preparing to perform an in-place upgrade from Windows 10 to Windows 11. Although the process is designed to preserve user data, applications, and settings, what is the most critical best practice to follow before beginning the upgrade?
Defragment the primary hard drive.
Perform a full backup of the user's data.
Disable the Windows Firewall to prevent installation interruptions.
Proceed directly with the upgrade, since backups are not required.
While an in-place upgrade is designed to keep user files, settings, and applications intact, there is always a risk of failure or data corruption. The most critical best practice before any major system modification, such as an OS upgrade, is to perform a full backup of all important data. This ensures that data can be recovered if the upgrade process encounters an error. Defragmenting a hard drive is less relevant for modern SSDs and not as critical as a backup. Disabling the firewall is a security risk and unnecessary for the upgrade process.
