Optimizing Windows

The_____________lets you view the applications and processes running on your computer as well as information about process and memory performance, network activity,and user activity. Task Manager (Taskmgr.exe)
Windows Vista Task Manager has six Tab: Applications tab, Processes tab, Services tab(not on XP), Performance Tab, Networking Tab, and Users Tab.
The Applications tab in Task Manager, each application can have one of two states: Running or not responding
The Processes tab in Task Manager Lists system services and other processes, CPU time, and memory use, and help you determine which applications are slowing down your system.
The Performance tab in Task Manager Identifies applications, processes using most CPU time
The Kernel Memory(MB) in the Performance tab in Task Manager indicates how much RAM and virtual memory the core kernel components of Windows are using.
System Configuration Utility (MSconfig.exe)temporary fix to disable program or service from loading. Use other tools, such as Services console or Start up folders, to permanently remove it from the start up process.
Windows Vista can also be used to monitor start up programs and to enable and disable a start up program is called Software Explore is more convenient to use than MSconfig.
The___________ is used to control the Windows and third-party services installed on a system. Services Console(Services.msc)
The Automatic (Delayed Start) in Services Console(Services.msc), starts shortly after startup, after the user logs on
The Automatic in Services Console(Services.msc), starts when Windows loads
The Manual in Services Console(Services.msc), starts as needed
The Disabled in Services Console(Services.msc), cannot be started
The Computer Management console (Compmgmt.msc) contains a group of Windows administrative tools useful for managing a local PC or other computers on the network.
Microsoft Management Console (MMC.exe) Windows utility to build customized console windows.
Console is a single window containing one or more administrative tools,such as Device Manager, or Disk Management.
Snap-ins are individual tools in a console
Tool for troubleshooting problems with Windows, applications, and hardware is called Eventvwr.msc
Three most important views of logs in Eventvwr.msc are Application log, Security log, System log
The___________ in Event Viewer is most important log other than security logs is records three error event types information, warning, and error events. System log
Reliability and Performance Monitor (Perfmon.msc) that Collects, records, and displays events (i.e., Data Collector Sets)
The Data Collector Sets in Reliability and Performance Monitor utility can be used to collect your own data about the system
The most important Windows component that holds information for Windows is the Registry Editor(regedit.exe) Database designed with a treelike structure (i.e., hierarchical database)
During start up, Windows built Registry in memory
After the registry is built in memory, it is organized into five treelike structures each segment called a KEY Each key can have subkeys
Data is organized in the Registry in hive files
A Windows registry key that stores information to determine which application is opened when the user double-clicks a file. HKEY_CLASSES_ROOT (HKCR)
A Windows registry key that contains Plug and Play information about the hardware configuration that is used by the computer at startup. HKEY_CURRENT_CONFIG (HKCC)
A Windows registry key that contains data about the current user. The key is built when a user logs on using data kept in the HKEY_USERS key and data kept in the Ntuser.dat file of the current user. HKEY_CURRENT_USER (HKCU)
An important Windows registry key that contains hardware, software, and security data. The key is built using data taken from the SAM hive, the Security hive, the Software hive, and the System hive and from data collected at startup about the hardware. HKEY_LOCAL_MACHINE (HKLM)
A Windows registry key that contains data about all users and is taken from the Default hive. HKEY_USERS (HKU)
The__________are caused by poorly written applications that request memory they don't need. Memory Leaks
Under Windows Vista, is a summary index designed to measure the overall performance of a system. You can use it to compare systems and identify performance bottlenecks in a particular system is called Windows Experience Index
As always, if valuable data is not backed up, back it up before you do anything else. that you can use the Vista Backup and Restore Center or the Windows XP Ntbackup utility to back up data
The Vista sidebar appears on the Windows desktop to hold miniapplications called Gadgets
Another way to seach memory leak is to use Task Manager click processs tab and click View, select Columns Verify that Memory Private Working Set, Handles, and Threads Columns are checked
There several ways you can access Task Manager: Press Ctrl+Shift+Esc
If an application is hung, try using the____________to end the task. Application tab
The__________graph indicates the percentage of time the CPU is currently being used. CPU Usage
The right_______________shows how much memory has recently been used. Physical Memory Usage History
The___________gives information about the overall system status. System frame
The____________frame list Total (amount of RAM), Cached (RAM that has recently been cached), and Free (RAM that recently has not been used). Physical Memory (MB)
The____________tab lets you monitor network activity and bandwidth used. Networking
____________in Windows Vista can also be used to monitor startup programs and to enable and disable a startup program. Software Explorer
The____________ records events about applications and Windows utilities such as when an application was unable to open a file Applicationl
The___________log records events based on audit policies, which an administrator sets to monitor user activity such as successful or unsuccessful attempts to access a file or log on to the system. Security
Five files stored in the C:\Windows\system32\config folder; these files are called Hives, and they are named the SAM
Back up a single registry key just before you edit the key. This method, called exporting a key
Windows Vista automatically makes a daily backup of the registry hive files to the C:\Windows\System32\Config\RegBack
