System Settings: Date, Time, Display, Mouse (सिस्टम सेटिंग्स)

Every computer user needs to personalize and adapt their machine—whether adjusting screen brightness to prevent eye fatigue, changing the date and time zone, adjusting mouse pointer speed, or configuring sound levels.

In Windows, system hardware and software preferences are configured through two management consoles: the modern Windows Settings App and the classic Control Panel.

1. Windows Settings vs Control Panel

• Windows Settings (Windows + I): A modern, touch-friendly interface introduced in Windows 10/11 designed for routine user adjustments (Display, Personalization, Network, Bluetooth, Accounts).
• Control Panel (कंट्रोल पैनल): The classic, powerful administrative console housing comprehensive, low-level technical configurations for hardware devices, power plans, and administrative tools.

2. Adjusting Date and Time (दिनांक और समय)

Your computer's real-time clock is powered by a small coin-shaped battery on the motherboard called the CMOS Battery (Complementary Metal-Oxide Semiconductor). It keeps track of time even when the PC is completely unplugged from the wall!

Steps to Change Date and Time:

1. 1
   Open Settings ($` ext{Win} + I$) $\implies$ Click Time & Language $\implies$ Date & Time.
2. 2
   Or right-click the digital clock on the far-right of the Taskbar and select "Adjust date/time".
3. 3
   Time Zone Setting: For India, ensure the Time Zone is set to (UTC +05:30) Chennai, Kolkata, Mumbai, New Delhi.
4. 4
   Internet Time Sync: Toggle "Set time automatically" to synchronize your clock with global network time servers (time.windows.com).

3. Display Settings & Screen Resolution (डिस्प्ले सेटिंग्स)

Configuring your screen display ensures sharp text and comfortable viewing:

• Screen Resolution (स्क्रीन रेजोल्यूशन): The number of individual horizontal and vertical dots (Pixels) displayed on the screen.
• Standard Full HD (FHD): 1920 x 1080 pixels.
• HD Ready: 1366 x 768 pixels.
• Higher resolution produces sharper text and allows more windows to fit side-by-side.
• Night Light (नाइट लाइट): Filters out harsh blue light and displays warmer amber colors at night to reduce eye strain and promote better sleep.
• Scaling (स्केलिंग): Scales text, apps, and icons (e.g. 100%, 125%, 150%) so small text is easily legible on high-resolution screens.

4. Mouse & Pointer Configuration (माउस सेटिंग्स)

Through Control Panel $\implies$ Mouse Properties, you can customize mouse hardware behavior:

1. 1
   Button Configuration (Left-Handed Mode): Switch primary and secondary buttons so left-handed users can click comfortably with their index finger.
2. 2
   Double-Click Speed: Adjust the timing speed required between two consecutive clicks to register a double-click.
3. 3
   Pointer Speed: Regulates how fast the cursor travels across the screen when moving the physical mouse.
4. 4
   Pointer Trails & Snap To: Adds visual ghost trails behind the cursor or automatically snaps the pointer to the default dialog button (e.g. "OK").
