1 Chapter 11: Maintaining and Optimizing Windows Vista

2 Using System Monitoring Tools
Before optimizing Windows Vista’s performance, monitor critical subsystems to determine how your system is currently performing. What system bottlenecks are present in your system?

3 Determining System Performance
Need to do 5 things to monitor the system effectively Create Baselines Identify System Bottlenecks Determine Trends Test Configuration Changes and Tuning Efforts Create Alert Thresholds

4 Creating Baselines Baseline: snapshot of current system performance
Gives a point of comparison against a system that is not running optimally Create baselines at the following times When system is first configured: no system load Regular intervals of typical usage Whenever changes are made to the software or hardware configuration

5 Identifying System Bottlenecks
Bottleneck: a system resource that is inefficient compared to the system as a whole Reliability and Performance Monitor will allow us to measure various system components in order to spot and correct bottlenecks.

6 Determining Trends Proactive Management: solve the problem before the problem happens Watch system baselines for increasing demands for RAM or Processor Time, and decreases in drive space

7 Testing Configuration Changes and Tuning Efforts
When you make configuration changes or tune your computer, you should measure the effects of those changes. Follow these recommendations: Make one change at a time Repeat monitoring with each change you make As you make changes, check the Event Logs. If you suspect network performance issues, compare the performance of a networked version with a local version.

8 Using Alerts for Problem Notification
Reliability and Performance Monitor can alert you when certain system thresholds have been reached. Example: Alert the Administrator when disk 2 has less than 10% free space available

9 Selecting the Appropriate View
Line View Report View Histogram View

10 Adding Counters

11 Performance Monitor Properties
General Properties Source Properties Data Properties Graph Properties Appearance Properties

12 Reliability Monitor

13 Data Collector Sets Used to collect data into a log so that it can be reviewed

14 Monitoring and Optimizing Memory
Two areas of memory to monitor: Physical RAM Page File Important counters to monitor: Memory > Available MBytes Memory > Pages/Sec Paging File > % Usage If memory seems to be a bottleneck: Add RAM Optimize page file settings Run less memory-intensive applications

15 Monitoring and Optimizing the Processor
Important counters to monitor: Processor > %Processor Time Processor > Interrupts/Sec System > Processor Queue Length If the processor seems to be a bottleneck: Run applications that are less CPU-intensive Upgrade the CPU Add a CPU if your computer supports multiple processors

16 Monitoring and Optimizing the Disk Subsystem
Important counters to monitor: PhysicalDisk > %Disk Time LogicalDisk > % Disk Time PhysicalDisk > Current Disk Queue Length LogicalDisk > Current Disk Queue Length LogicalDisk > % Free Space If the disk subsystem seems to be a bottleneck: Use faster disks or hardware controllers Confirm that you are using the latest drivers Take advantage of disk striping if possible Add another disk controller for load balancing Use Disk Defragmenter Use DFS to balance workload over a network

17 Monitoring and Optimizing the Network Subsystem
Important counters to monitor: Network Interface > Bytes Total/Sec TCPv4 > Segments/Sec If the network subsystem seems to be a bottleneck: Use only the network protocols you need Use network cards that use your computer’s full bus width Use faster network cards: 100 Mbps, 1 Gbps

18 Memory Diagnostics Tool
Used to test your computer’s memory

19 Problem Reports and Solutions
Replaces Dr. Watson Enables you to track system problems and check for solutions to those problems.

20 Tools to Discover System Information
Task Manager Performance Information and Tools

21 System Information

22 Task Manager

23 Performance Information and Tools

24 System Tool in Control Panel

25 System Configuration

26 Task Scheduler Completely overhauled for Vista
Used to schedule actions to occur at specified intervals

27 Scheduling Tasks with Task Scheduler
Triggers, Actions, and Conditions

28 Event Viewer Completely overhauled for Vista
Tracks events that occur in the system Old, familiar logs: Application Security System And some brand new logs: Setup Forwarded Events

29 Indexing Options

30 Remote Desktop Remote Desktop is a service that allows you to remotely take control of your computer from another location. For example, you could access your work computer from home or while traveling on business.

31 Remote Assistance Used to request assistance from another user
Compatible with: Windows XP Windows Server 2003 Windows Vista

32 Differences between Remote Assistance and Remote Desktop
Remote Desktop only allows one user to see the desktop at a time. Remote Assistance allows both local and remote users to see the desktop. Remote Desktop does not require an invitation to connect. Remote Assistance requires the remote user to invite assistance.

33 Safeguarding Your Computer and Recovering from Disaster
Prepare for disaster: it’s not fun, but it’s better than being unprepared when disaster strikes. Windows Vista Recovery Techniques: Event Viewer Safe Mode Last Known Good Configuration Startup Repair Tool Backup and Restore Center System Restore

34 Advanced Boot Options Accessed by pressing F8 at startup Options:
Safe Mode Safe Mode with Networking Safe Mode with Command Prompt Enable Boot Logging Enable Low-Resolution Video (640x480) Last Known Good Configuration (advanced) Directory Services Restore Mode Debugging Mode Disable Automatic Restart on System Failure Disable Driver Signature Enforcement Start Windows Normally

35 Startup Repair Tool Used to correct problems related to missing or corrupted system files Cannot repair hardware failures Cannot recover personal files that have been corrupted, damaged by viruses, or deleted

36 Backup and Restore Center

37 Backup and Restore Center
Used to perform the following tasks: Back up files Restore files Change automatic backup settings Create an image of your entire computer Restore an image of your computer Restore a previous version of files on your computer using System Restore Create a restore point using System Protection

38 Backing Up Files with Backup and Restore Center
Backup and Restore Center can back up the following: Pictures Music Videos Documents TV shows recorded with Windows Media Center Compressed files (.zip, .cab, .iso) Additional files that do not correspond to any of the other categories

39 Backup and Restore Center Limitations
Backup and Restore Center will NEVER back up the following: System files Program files User Profile Settings Files encrypted by EFS Files on FAT partitions Files in the Recycle Bin Temporary Files Web-based

40 Creating an Image with Windows Complete PC Backup
Used to create a snapshot image of your entire computer, including: Programs System Settings Files Everything!

41 System Restore Creates restore points that can be used to restore system files and settings to an earlier point in time Will not affect personal files Restore points are created: Every day Before installing applications or drivers Before significant system events Before restoring files with System Restore Manually upon request
