Which troubleshooting steps did the technician MOST likely fail to complete in the situation that on a workstation, a user is experiencing slow performance. A technician analyzes and speculates that the performance issue is caused by an overabundance of background services running at launch. The technician investigates the issue and then locates and shuts many services that have been running at startup. The technician then notifies the user that the remediation is complete; the next morning, the technician receives a call from a similar user reporting performance is still slow?
