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
Open Settings ($` ext{Win} + I$) $\implies$ Click Time & Language $\implies$ Date & Time.
2
Or right-click the digital clock on the far-right of the Taskbar and select "Adjust date/time".
3
Time Zone Setting: For India, ensure the Time Zone is set to (UTC +05:30) Chennai, Kolkata, Mumbai, New Delhi.
4
Internet Time Sync: Toggle "Set time automatically" to synchronize your clock with global network time servers (time.windows.com).
Note
If your computer clock constantly resets back to an old year (e.g. 2005) every time you turn on the PC, your motherboard's CMOS battery has discharged and needs physical replacement.
