A user has a problem with the touchpad on their Windows XP notebook. The problem started after a new manufacturer hardware update was installed. Which of the following should a technician do FIRST…

Manually editing Registry device properties is a high-risk operation that could worsen the issue and is not the appropriate first step when a known, reversible driver change is the probable cause.

Contacting manufacturer support is appropriate only after self-service troubleshooting options have been exhausted, not as the first response to a driver regression.

Device Manager's Roll Back Driver feature reinstates the previously working driver version, directly addressing the root cause since the touchpad malfunction began only after the new manufacturer driver was installed - this is a non-destructive, targeted action that does not require external support or system-wide changes.

Updating the OS service pack does not address a specific driver compatibility regression and introduces a much larger system change than the problem requires.
