A technician is troubleshooting a Windows computer experiencing slow startup. Which of the following steps should the technician take first to determine whether startup processes are responsible for the slow startup? A. The technician should permanently disable all startup processes in System Configuration.
B. The technician should measure the time it takes to start the system using a normal boot and compare that time against the time it takes for the system to perform a clean boot.
C. The technician should back up user data and reinstall Windows and all applications.
D. The technician should disable all scheduled tasks in Task Scheduler and reboot the system.

The correct option is;

The technician should measure the time it takes to start the system using a normal boot and compare that time against the time for the system to perform a clean boot.

Explanation:

Clean boot is the process of starting the Windows operating system where the number of drivers as well as startup programs enabled are minimal in order to ascertain if the cause of a slow system startup is due startup interfering programs or drivers

A clean boot operating system startup and a startup in Safe Mode are similar with the difference being the higher level of control on what to run during start up offered by clean boot to aid troubleshooting startup issues.
