2.1.6. Configure Microsoft Windows settings. (Obj. 1.6)

💡 First Principle: A technician must know how to navigate and configure core Windows settings to customize the user experience and optimize system performance.

Beyond the deep system tools, a technician spends a significant amount of time in the standard Windows settings interfaces, configuring the system to meet user needs and corporate policies. In modern Windows (10/11), these settings are split between the new Settings app and the legacy Control Panel. While Microsoft is moving more options to the Settings app, many advanced configurations still reside in the Control Panel, and you must be comfortable with both. These settings control everything from the visual appearance to power management and network identity.

Key areas you must master include:

• System Settings: This is a broad category. Here you can change the computer name (essential for identifying it on a network), configure Remote Desktop and Remote Assistance, and manage Power & Sleep settings. Under Advanced system settings > Performance you also size virtual memory: the pagefile (pagefile.sys) is disk space Windows uses as an overflow for RAM, paging out little-used memory so the system can meet demands beyond physical RAM. It is far slower than RAM, so it adds capacity, not speed.
• Power Options (Control Panel): This is a critical area for managing performance and energy use, especially on laptops. You can create and customize power plans (e.g., Balanced, Power Saver, High Performance). A key function here is defining what happens when the power button is pressed or the laptop lid is closed (e.g., Sleep, Hibernate, Shut down, Do nothing).
  • Sleep vs. Hibernate vs. Fast Startup: Sleep keeps the session in powered RAM for near-instant resume but still draws power. Hibernate writes the contents of RAM to hiberfil.sys on disk and powers off completely, so the session survives a dead battery and resumes where it left off. Fast Startup (on by default, under "Choose what the power buttons do") is a shutdown setting: Windows logs users off but hibernates the kernel session, so the next cold boot is faster. A Restart bypasses Fast Startup, which is why a restart, not a shutdown, is the right step when a driver or update needs a clean boot.
• Devices and Printers: Manage installed hardware like printers, scanners, and Bluetooth devices. This is where you set the default printer.
• More settings locations to know:
  • Display (Settings > System > Display): Scale enlarges text, apps and icons (e.g., 150%) while keeping the panel's native resolution - the right fix for tiny text on a high-DPI/4K screen; lowering the resolution instead makes the image blurry.
  • Apps (Settings > Apps): Installed apps uninstalls Store and desktop apps; Default apps chooses which app opens each file type or link type (file associations).
  • Bluetooth & devices (Settings): Pair new Bluetooth devices with Add device; also home to the AutoPlay settings (Settings > Devices in Windows 10), where "Use AutoPlay for all media and devices" can be turned off (the Control Panel AutoPlay applet does the same). Device Manager manages drivers; it does not pair devices.
  • Credential Manager (Control Panel > User Accounts): Stores and lets you edit or remove saved Web Credentials and Windows Credentials (e.g., passwords for network shares and mapped drives) - the first place to look when a stale saved password keeps failing.
  • Internet Options (inetcpl.cpl): System-wide browser settings - security zones, clearing browsing data, and proxy configuration (Connections > LAN settings).
  • Ease of Access / Accessibility: For low vision use Magnifier, Narrator (screen reader) and high-contrast themes; Sticky Keys, Filter Keys and Mouse Keys are keyboard/mobility aids, not vision aids.
• Programs and Features (Control Panel - appwiz.cpl): The primary location for uninstalling desktop applications.
• Network and Sharing Center (Control Panel): The hub for managing network adapters, setting up new connections, and configuring sharing options.
• User Accounts: Manage local user accounts, change account types (Standard User vs. Administrator), and configure User Account Control (UAC) settings. The principle of least privilege dictates that users should run as a Standard User for daily tasks. UAC exists to prevent unauthorized elevation of privileges: programs run with standard rights, and a change that needs admin rights must first be approved at a UAC prompt. Give each person their own account so each gets a separate profile (desktop, documents, and settings).
• File Explorer Options: Customize the look and feel of File Explorer. Critically, this is where you can check the box to "Show hidden files, folders, and drives" and uncheck "Hide extensions for known file types", two essential steps for advanced troubleshooting and malware identification. Extensions are hidden by default only to keep the view simple for non-technical users. It is a convenience, not a security feature, and it lets invoice.pdf.exe pass for invoice.pdf.

Technician's Action Plan: Scenario: A user who frequently gives presentations has a new laptop. They are frustrated because every time they close the lid to move from their desk to the conference room, the laptop goes to sleep, and they have to wait for it to wake up and reconnect to the projector. They want it to stay on when the lid is closed, as long as it's plugged into power.

1. Identify the Correct Tool: Recognize this is a power management setting. The most direct way to access it is through the Control Panel's Power Options.
2. Navigate to the Setting: Guide the user to open the Control Panel. They can do this by searching for "Control Panel" in the Start Menu.
3. Locate Power Options: Tell them to find and click on "Power Options".
4. Find the Lid Close Action: On the left-hand side of the Power Options window, there is a link that says "Choose what closing the lid does". Have them click it.
5. Configure the Desired Behavior: The next screen shows options for "On battery" and "Plugged in". Instruct the user to find the row for "When I close the lid" and change the dropdown menu in the "Plugged in" column from "Sleep" to "Do nothing".
6. Save and Verify: Have them click "Save changes". Now, ask them to plug in the laptop, close the lid for a few seconds, and then open it again. They will see that the screen is still on and active, confirming the setting has been applied correctly. Explain that it will still go to sleep on battery power to preserve the charge.

Reflection Question: Why is it a best practice for users to operate their Windows PCs with a "Standard User" account for daily tasks, rather than an "Administrator" account?
