  2. Agenda • Chapter 8: Managing and MonitoringWindows 7 Performance • Exercise / Lab • Quiz

  3. Updating Windows 7 • One of the primary tasks of a desktop technician • Should be familiar with: • Types of update releases • Methods for deploying updates

  4. Understanding Update Types • Hotfixes • An update to address a specific problem or issue • Security updates • To patch vulnerability in Windows 7 security • Include a security bulletin and a Knowledge Base article • Cumulative updates (rollups) • Service packs

  5. Update Categories • Important updates • Recommended updates • Optional updates • Updates that contain enhancements or new features that are not essential for the proper functioning of the operating system • Device drivers

  6. Applying Updates • Windows Update • Detect, Download, Installation • Windows Server Update Services (WSUS) • System Center Configuration Manager (SCCM)

  7. Configuring the Windows Update • Windows Update control panel • Group Policy settings

  8. Important Updates Options • Install updates automatically (recommended) • Download updates but let me choose whether to install them • Check for updates but let me choose whether to download and install them • Never check for updates (not recommended)

  9. Configuring Windows Update Using Group Policy • Local Group Policy settings to configure the client OR • Distribute the settings using AD Domain Services (AD DS) • Group Policy is THE ONLY WAY WSUS • The recommended practice • Create a new Group Policy object (GPO) • Configure the required settings • Link the GPO to an appropriate AD DS object • For multiple WSUS servers, you can distribute the client load among them by creating a separate GPO • Comp Configuration -> Admin Templates -> Windows Components -> Windows Update

  10. Triggering an Update • Windows download automatically OR • Click Check for updates • Select the updates you want to install • Select each update to display information • You can hide the update • You can review the update history • Select the checkboxes on the updates that you want to install • Click OK • The client installs the selected updates

  11. Using Windows Server Update Services • Downloads updates from the Microsoft Update Web site • Stores them for administrator evaluation • Administrators select the updates to deploy • Computers on the network download updates from WSUS server using a reconfigured Windows Update Client

  12. Deploying WSUS • Must be installed on Windows Server 2008 R2 • WSUS software is a free download from Microsoft • Web-based product • The Web Server (IIS) role must be added • Requires a database • Windows Internal Database, or SQL Server for larger networks

  13. Managing WSUS • Update Services console, shown in Figure 8-14 • WSUS management consists of two main tasks: • Synchronization • a WSUS server obtains the updates • To synchronize with the Microsoft Update servers on the Internet, or with another WSUS server • Configure synchronizations to occur automatically, at scheduled intervals. • Approval of updates

  14. Configuring WSUS Clients • Configured through Group Policy • Cannot be done in Windows Update program

  15. Monitoring Performance • Tools to enable you to locate poorly performing components (Since Vista): • Event Viewer • Performance Information and Tools • Performance and Reliability Monitor

  16. Using Event Viewer • To record information about system activities • Events are stored in log files: • System Log, Security Log, and Application Log • Setup Log and Forwarded Events

  17. Viewing Windows Logs • Custom view • A filtered version of a particular log, configured to display only certain events • Regular view (Grouped events)

  18. Viewing Windows Logs • Application • Contains information about specific programs running on the computer • Security • Contains information about security-related events, such as failed logons, attempts to access protected resources, and success or failure of audited events • Setup • Contains information about the OS installation and setup history • System • Contains information about events generated by the OS, such as services and device drivers • Forwarded Events • Contains events received from other computers on the network via subscriptions

  19. Performance Information and Tools • Windows Experience Index • Rates computer’s components and assigns a base score reflecting the score of the lowest rated component on your system • Hardware upgrades improve performance • Conserve system resources to enhance performance

  20. Performance Monitor Console • Show real-time information in graph or report • You have a collections of performance counters • Launch via control panel, MMC console, Perfmon.msc, or Computer management console

  21. Adding Counters • Computer • The name of the computer you want to monitor with the selected counter • Performance object • A category representing a specific hardware or software component in the computer • Performance counter • A statistic representing a specific aspect of the selected performance object’s activities. • Instance • An element representing a specific occurrence of the selected performance counter. Such as Total or Average • Click Add to add the counter to the Added Counters list

  22. Creating an Effective Display • Limit the number of counters • Modify the counter display properties • Choose counters with comparable values

  23. Creating Data Collector Sets • Data collector set • To capture counter statistics in the Performance Monitor console for later review • Baseline • A set of readings, captured under normal operating conditions

  24. Using Reliability Monitor • Collects and tracks information about system stability to calculate a stability index • Based on the number and type of negative events occurring in the preceding 28 days

  25. Managing Performance • Windows 7 includes a variety of controls and technologies that enable technical specialists to enhance and fine-tune the performance of their workstation: • Task Manager • Resource Monitor • Process Manager • System Configuration tool (msconfig)

  26. Managing Services • A program that the computer launches and leaves running continuously in the background • Automatically loaded when the system boots • Services.msc • You can specify how service load • Automatic • Automatic (Delayed start) • Manual • Disabled

  27. Configuring Performance Option Settings • Adjust visual effects • Choose the cosmetic visual elements you want the computer to use • On the Advanced tab • Configure the system processor to allocate more resources to running programs or background activities • The Virtual Memory dialog box • A paging file • An area of disk space that Windows uses to store data that overflows from system memory

  28. Configuring Power Settings • Enable you to throttle various system components to optimize their power utilization • Power Plan

  29. Configuring Hard Disk Caching • Write caching is when the device stores data in temporary memory until the slower devices can catch up • Disk writing can happen in the background while a user continues to work

  30. Using ReadyBoost • Enables you to use the storage space on a USB flash drive to free up system memory for other uses • SuperFetch is a caching routine that enables Windows 7 to restore user access to applications much faster than previous OS • It stores the frequently used data in a Cache memory rather than page file

  31. Assignment • Matching • Multiple Choice • Case Scenario 8-1
