CompTIA A+ 220-1102 – Windows User & System Settings

Windows Interfaces

• Graphical User Interface (GUI) / shell
  • Primary human-computer interaction layer in Windows.
  • Provides windows, icons, menus, and pointers—collectively remembered with the mnemonic “WIMP.”
  • Significance: hides the complexity of the underlying OS; lowers the learning curve for non-technical users.
• Desktop
  • Workspace that can hold shortcuts, files, and system objects such as the Recycle Bin.
  • Wallpaper + visual theme can be personalized for usability or corporate branding.
• Start Menu
  • Central launch point for apps, settings, power controls, and search.
  • Houses a scrolling All Apps list and pinned tiles/shortcuts.
  • Example: Type “calc” to open Calculator without browsing folders.
• Taskbar
  • Hosts running-app buttons, the system clock, notification area (aka system tray), and quick-launch icons.
  • Customizable position (bottom/top/left/right) and auto-hide feature for screen real estate.
• Instant Search (a.k.a. Windows Search / Start Search)
  • Real-time indexing allows keystroke-driven discovery of programs, files, emails, and Control Panel items.
  • Uses Indexing Options service; metadata and file contents cached for speed.
• Task View
  • Exposé-style view of open windows plus Virtual Desktops manager (WIN+TAB shortcut).
  • Great for separating workspaces (e.g., “Research” vs. “Gaming”).
• Notification Area
  • Small icons near the clock report background app status, network, battery, security alerts, etc.
  • Customizable via Settings ➜ Personalization ➜ Taskbar ➜ “Select which icons appear.”

Recycle Bin & Pinned Apps Example (Screenshot Walk-Through)

• Demonstrates a modern Windows 10/11 Start layout featuring:
  • Pinned applications: Edge, Teams, WhatsApp, Xbox, Spotify, Disney+, TikTok, etc.
  • Recommended section: recent installers (“Get Started”, “Zoom”).
  • System icons: Recycle Bin on Desktop; Search box labeled “Type here to search.”
• Teaching moment: Users can right-click any tile ➜ “Unpin from Start” or drag to rearrange—illustrates GUI customization.

Windows Settings vs. Control Panel

• Windows Settings app (introduced in Win 8, revamped in 10/11)
  • Touch-friendly, simplified categories (System, Devices, Network & Internet, etc.).
  • Microsoft is gradually migrating legacy Control Panel features here.
• Control Panel
  • Legacy MMC-style interface with applets (e.g., “Device Manager”, “Programs and Features”).
  • View modes: Category, Large icons, Small icons.
  • Power-tip: Type control in Run dialog (WIN+R) to launch instantly.

Account Settings

• Account Types
  • Local Account: credentials stored only on the PC—good for offline or lab environments.
  • Microsoft Account: cloud-linked; enables OneDrive sync, Microsoft Store, BitLocker recovery keys.
• Permission Levels
  • Administrator: full control, software install, UAC elevation.
  • Standard User: limited; mitigates malware risk.
  • Best practice: daily driver = Standard, separate Admin for maintenance.
• Sign-in Options
  • Password, PIN, Windows Hello (biometric), Security Key, Picture Password.
  • Security vs. convenience trade-off: PIN is device-specific; Hello facial recognition resists shoulder-surfing.
• Family & Other Users
  • Add supervised child accounts with screen-time limits.
  • Enterprise: “Other users” supports AzureAD / domain joins.
• User Accounts Control Panel Applet
  • Manage other accounts, change account type, configure User Account Control (UAC) slider.
  • UAC prompts reduce elevation attacks; higher setting = more secure.

Privacy Settings

• Data Collection
  • Telemetry levels: Basic vs. Full (Windows Insider, etc.).
  • Organizations may use Group Policy to restrict.
• Ad & Services Personalization
  • Advertising ID per user; can be disabled to minimize targeted ads.
• Speech Recognition & Typing Personalization
  • Cloud-based language model improves Cortana but stores voice clips.
• Diagnostics
  • Error reports forwarded to Microsoft; helpful for patch prioritization.
• Activity History
  • Timeline feature syncs PC usage across devices; disable for privacy.
• App Permissions
  • Per-app toggles for Camera, Microphone, Location, Contacts, etc.
  • Example: revoke microphone for “RandomGame.exe” to mitigate eavesdropping.

Desktop & Personalization Settings

• Time & Language
  • Auto-sync time with NTP / domain controller.
  • Region: affects \text{Currency},\ \text{Date},\ \text{Decimal separators}.
  • Keyboard Layout: add QWERTZ, DVORAK, IME for Japanese.
• Personalization
  • Themes bundle wallpaper, colors, sounds, mouse cursors.
  • Lock Screen: choose slideshow, app status (e.g., Calendar).
  • Start & Taskbar: enable full-screen Start for kiosk mode.

Ease of Access (Accessibility)

• Vision
  • High-contrast themes; font scaling (125 %–250 %).
  • Pointer and cursor size/color adjustment.
  • Narrator (screen reader) and Magnifier (WIN + + / - hotkeys).
