Discussion 1
"Diagnosing and Troubleshooting Performance Issues" Please respond to the following:
• Suppose you have installed Windows 8 on a user's computer four days ago. At the time, it functioned normally and performed optimally. Today, the user calls you to say that the computer is starting to run very slowly. A few hours later, the central processing unit (CPU) and disk are at 100% utilization at all times. Using the information provided in Chapter 23, suggest the approach you would take to troubleshoot the user's computer. Speculate on the questions you might ask the user and the tools you would use to improve the computer's performance. Provide a rationale for your response.
• The Windows Experience Index is Microsoft's measurement of how well a computer will perform running general computing tasks. With the release of Windows 8.1, this feature has been removed. Support or challenge Microsoft's decision to remove this feature from Windows 8.1. Support your position with at least one example that demonstrates the value or lack of value that the Windows Experience Index provides for troubleshooting performance issues.
