Need to avoid any misleading information. For example, if the user is on a capped connection, downloading a large driver might not be advisable. But since the question is about speed, focus on the speed issue.
Also, considering Windows 7's obsolescence, maybe the user can't use modern tools, so suggest compatible solutions only. For example, recommending a legacy download manager that works on Windows 7.
Finally, end with a note about security, advising to keep drivers updated and the system secure post-Windows 7 support. Maybe even a quick tip on how to check for driver updates automatically.
