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
• 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
• 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
• 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
• 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 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
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 (Delayed start)
Configuring Performance Option
• 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
• 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
• 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
• Matching
• Multiple Choice
• Case Scenario 8-1
