    Study Notes

    Overview

    • This chapter covers working with the Windows Registry, understanding the boot process, managing processes, services, and threads, and exploring Windows tools for programmers.

    Registry

    • The Registry is a vast database storing PC information, including hardware details, network settings, user preferences, file types, and application data.
    • Windows stores these Registry files in the %SystemRoot%\System32\config folder.

    Accessing the Registry

    • The Registry Editor (regedit) provides direct access to the Registry.
    • You can access the Registry Editor by typing "regedit" in a command prompt or the Start/Search bar.

    Registry Components

    • The Registry is structured like a tree, mirroring PC folders.
    • When opening the Registry Editor, you'll see five main root keys:
      • HKEY_CLASSES_ROOT
      • HKEY_CURRENT_USER
      • HKEY_USERS
      • HKEY_LOCAL_MACHINE
      • HKEY_CURRENT_CONFIG

    Registry Components (continued)

    • Root keys are composed of subkeys.
    • Subkeys can contain other subkeys or values.
    • The Registry Editor displays keys/subkeys on the left and values on the right.

    Registry Components (continued)

    • HKEY_CLASSES_ROOT defines standard class objects (file types and associations) for Windows.
    • HKEY_CURRENT_USER and HKEY_USERS store personalized data for users.
    • HKEY_LOCAL_MACHINE stores system configurations not tied to specific users.
    • HKEY_CURRENT_CONFIG holds currently active options.

    Talkin' Registry

    • Registry nomenclature uses a path syntax (e.g., HKLM\SOFTWARE\Blizzard Technologies\World of Warcraft).
    • This syntax describes the location of a specific registry value.
    • Keys and subkeys can have multiple values.

    Talkin' Registry (continued)

    • Registry values have defined data types:
      • String value: any form of data
      • Binary value: a string of ones and zeros
      • DWORD value: 32-bit binary value
      • QWORD value: 64-bit binary value

    Manual Registry Edits

    • Manual Registry editing can lead to Windows malfunctions (e.g., application failure, system boot issues).
    • Always back up the Registry before making changes.
    • Create backups using different storage media (e.g., USB drive).
    • Reboot the system after editing to ensure changes take effect.

    Manual Registry Edits (continued)

    • The Registry Editor's export feature enables saving the entire Registry or a specified key/subkey (including its subkeys and values).

    Command-Line Registry Editing Tools

    • The reg command is a full Registry editing tool enabling viewing, importing, exporting, comparing Registry versions and performing precise edits.
    • The regsvr32 command modifies the Registry by registering or unregistering DLL files.

    The Boot Process

    • Current Windows support BIOS and UEFI boot processes.
    • BIOS-based systems scan a hard drive for the Master Boot Record (MBR). The MBR holds the code to the Boot Manager (bootmgr) file. Bootmgr loads the winload.exe file which readies the system to load the OS kernel.
    • UEFI systems load the bootmgr file directly.

    The Boot Process (continued)

    • Bootmgr reads data from the Boot Configuration Data (BCD) file. This file lists installed operating systems and bootstrap instructions.
    • After selecting an OS, bootmgr loads winload.exe which loads the OS kernel.

    The Boot Process (continued)

    • Winload.exe loads:
      • Hardware abstraction layer
      • The System Registry
      • Boot device drivers into memory before the OS takes over.
    • The operating system loads its required process and components and displays the Windows logo.

    Processes, Services, and Threads

    • Windows programs are executable files stored on storage devices.
    • When a program starts, Windows loads it into RAM as a process. The CPU reads and executes the program's code.
    • Windows is a multitasking OS capable of running multiple processes simultaneously.

    Processes, Services, and Threads (continued)

    • Some processes (e.g., applications) run in the foreground, while others (e.g., services) operate in the background.

    Task Manager

    • The Windows Task Manager offers a central platform to manage applications, processes, and services.
    • Task Manager opening methods include CTRL+SHIFT+ESC, searching for "taskmgr" in the Start menu, and using CTRL+ALT+DELETE.

    Task Manager in Windows Vista/7

    • The Applications tab displays running applications.
    • Force close applications that don't respond.
    • Switch to an application to activate it.
    • Create new applications using known executables.

    Task Manager in Windows Vista/7 (continued)

    • The Processes tab lists all running processes, named after their executable files.
    • All processes have a user name and a unique process ID (PID). Task Manager displays PID when checked under View.

    Task Manager in Windows Vista/7 (continued)

    • Each process has a unique process ID (PID)..
    • Task Manager shows default process names, not PIDs .
    • The PID allows precise identification in lieu of process name.

    Task Manager in Windows Vista/7 (continued)

    • Processes display CPU usage and RAM usage.
    • Displaying all users process requires checking "Show processes from all users" in Task Manager.

    Task Manager in Windows Vista/7 (continued)

    • Ending a process closes the associated application.
    • Right-clicking on a process offers options like opening its file location, debugging, and enabling UAC virtualization (User Account Control).
    • Services tab shows programs managing Windows.

    Task Manager in Windows Vista/7 (continued)

    • Use the "Services" tab to manage services, which are background tasks.
    • Services function by using their own status column.
    • Start/stop/configure services using Services Control Panel tool.

    Task Manager in Windows Vista/7 (continued)

    • Performance tab shows CPU and RAM resource usage to monitor computer resource demands.
    • Performance info includes CPU usage, available RAM, size of disk cache, commit charge, and kernel memory.
    • Identify applications using the most resources.

    Task Manager in Windows Vista/7 (continued)

    • The Networking tab provides a network overview.

    • The Startup tab helps disable unwanted startup programs.
    • The Users tab displays running programs linked to users, presenting a clear picture of resource usage.
    • The Details tab continues functionality from the previous Processes tab.
    • The Services tab is unchanged.

    Task Manager in Windows 8/8.1/10 (continued)

    • The tasklist and taskkill commands enable command-line interaction with processes.
    • Use tasklist to view active processes on local or remote PCs.
    • Taskkill enables ending processes using their name or PID.

    Performance Tools

    • Reliability and Performance Monitor tools in Windows track resource usage metrics.
    • An object represents a system component (with defined attributes).
    • A counter records specific information on an object.

    Performance Tools (continued)

    • You can build your own or use predefined system collector sets.
    • Data Collector Sets help schedule data collection for precise reports.

    Component Services

    • Component services enable programmers to share data objects (program elements) between applications on a single computer or amongst a network.

    Component Services (continued)

    • Component Services are needed for troubleshooting rare errors or software programmer-driven changes to data sharing within the network.

    Data Sources

    • Open Database Connectivity (ODBC) standard helps developers write databases and apps that interact with them without being concerned about the specific OS or program used.
    • SQL data sources enable direct interaction with databases regardless of the specific application and OS.

    Data Sources (continued)

    • The ODBC Data Source Administrator configures ODBC, creating and managing Data Source Names (DSNs) that direct queries to specific databases.
