Presentation slides are here.

Objectives
  • Update Windows 7.
  • Use Event Viewer.
  • Use Performance Monitor.
  • Manage Performance Settings
Vocabulary
Background Intelligent Transfer Service (BITS) An HTTP-based file transfer service that downloads files using only the network’s idle bandwidth. This enables Windows Update to perform downloads without affecting other applications that are using the network. BITS downloads are also resumable, in the event they are interrupted.

baseline A set of readings, captured under normal operating conditions, which you can save and compare to readings taken at a later time. By comparing the baseline readings to the workstation’s current readings at regular intervals, you might detect trends that eventually affect the computer’s performance

channel A log for a Windows component in the Event Viewer console. When you expand the Applications and Services Logs folder, you see logs for Windows applications, such as Internet Explorer. Then, when you expand the Microsoft and Windows folders, you see a long list of Windows components. Each of these components has its own separate log, called a channel.

collector A Windows 7 computer, configured with an Event Viewer subscription, which receives event information from other computers over the network. 

data collector set A collection of performance counter readings gathered under controlled circumstances for evaluation at a later time. 

events A single record in a log of Windows system activities, viewable in the Event Viewer console.

hotfix A software update consisting of one or more files designed to address a specific problem or issue with the operating system. 

instance An element representing a specific occurrence of a specific performance counter. 

performance counter A statistical element that the Performance Monitor application can track in a variety of ways. You can use Performance Monitor to create a customized graph or report containing any performance counters you choose.

performance object A category representing a specific hardware or software component in the computer. 

ReadyBoost A Windows 7 feature that enables the operating system to use the storage space on a USB flash drive as additional system memory. ReadyBoost uses a flash drive to store the SuperFetch cache, thereby freeing up the system memory where the cache would ordinarily be preloaded.

SuperFetch An enhanced method of prefetching in which the system maintains a more detailed profile of the computer’s disk usage and can make better guesses about what information to include in the cache. In combination with ReadyBoost, SuperFetch can provide a substantial enhancement to a Windows 7 system’s performance.

Windows Experience Index A system rating that quantifies the capabilities of a Windows 7 computer by breaking it down into categories and assigning each one a rating. 

Windows Server Update Services (WSUS) A Microsoft product for medium to large networks that conserves bandwidth by downloading updates from the Internet once and then providing them to Windows Update clients on the local network. WSUS also enables administrators to select the updates they want to release to the clients, thus giving them the opportunity to evaluate and test the updates first, and then schedule the deployment.
