CN1176 Computer Support Kemtis Kunanuraksapong MSIS with Distinction MCT, MCTS, MCDST, MCP, A+ Agenda • Chapter 8: Managing and Monitoring Windows 7 Performance • Exercise / Lab • Quiz Updating Windows 7 • One of the primary tasks of a desktop technician • Should be familiar with: ▫ Types of update releases ▫ Methods for deploying updates 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 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 Applying Updates • Windows Update ▫ Detect, Download, Installation • Windows Server Update Services (WSUS) • System Center Configuration Manager (SCCM) Configuring the Windows Update • Windows Update control panel • Group Policy settings 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) 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 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 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 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 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 Configuring WSUS Clients • Configured through Group Policy ▫ Cannot be done in Windows Update program Monitoring Performance • Tools to enable you to locate poorly performing components (Since Vista): ▫ Event Viewer ▫ Performance Information and Tools ▫ Performance and Reliability Monitor 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 Viewing Windows Logs • Custom view ▫ A filtered version of a particular log, configured to display only certain events • Regular view (Grouped events) 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 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 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 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 Creating an Effective Display • Limit the number of counters • Modify the counter display properties • Choose counters with comparable values 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 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 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) 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 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 Configuring Power Settings • Enable you to throttle various system components to optimize their power utilization • Power Plan 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 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 Assignment • Matching • Multiple Choice • Case Scenario 8-1
