An OTP (One Time Password) is valid for exactly 30–60 seconds.
Even though no one stores it anywhere. So, how does the server verify it without ever saving it?Well, that’s usually called a Time-based One-Time Password (TOTP).
Here’s how it actually works:
• A secret key is shared between your device and the server (only once)
• Both use the current time window (like 30 seconds)
• And a secure algorithm (HMAC)Using these, both sides generate the same OTP independently.
✅ No storage
✅ No database lookup
✅ Just math + timeWhen you enter the OTP, the server simply regenerates it and checks:
👉 “Does this match?”That’s how your OTP is verified… without ever being saved. 🔐

High CPU usage in Windows 11 usually means a process is using more CPU cycles than it should. It could be due to excessive background apps, pending Windows updates, corrupted system files, or high-resource processes like antivirus scans and indexers.
Fixes for High CPU Usage (Windows 11)
Restart Your PC: This is the quickest way to clear stuck processes and memory.
Use Task Manager: Press Ctrl + Shift + Esc, find processes with high CPU usage, right-click them, and select "End task".
Disable Startup Apps: In Task Manager, go to the "Startup apps" tab, right-click unnecessary apps, and select "Disable".
Update Windows & Drivers: Go to Settings > Windows Update to ensure you have the latest performance patches.
Check Power Settings: Search for "Choose a power plan" in the Control Panel, and select "Balanced" or "High Performance".
Scan for Malware: Run a full scan with Windows Defender, as viruses can cause high CPU usage.
Disable SysMain (Superfetch): Search for "Services," find "SysMain," right-click to stop it, which can reduce background resource usage.
Disable High Precision Event Timer: In Device Manager, find "High precision event timer" under System Devices, right-click, and disable it

A VPN protocol is a set of rules determining how data is encrypted and transmitted between a user's device and a VPN server. It creates a secure, encrypted "tunnel" for online traffic, protecting data from hackers and ISPs by routing it through a remote server.
Top VPN Protocols in 2026
WireGuard: The industry leader in 2026, offering superior speed and lower battery consumption on mobile devices due to its lightweight code.
OpenVPN: A versatile and highly secure open-source protocol widely used for its reliability, though it can be slower than WireGuard.
IKEv2/IPsec: Excellent for mobile users, offering rapid reconnection if the internet connection is temporarily lost.
SSTP: Highly effective at bypassing firewalls, though it is mostly limited to Windows systems.
L2TP/IPsec: An older, secure option that is less commonly used in 2026 due to slower speeds compared to modern alternatives
How to Choose a Protocol
Speed/Streaming/Gaming: Use WireGuard.
Security/Privacy: Use OpenVPN.
Mobile Devices: Use IKEv2

A Blue Screen Error (BSOD) is not just a system crash — it’s a critical warning from the operating system.
🔍 What is the Actual Problem?
The main reason behind most BSOD errors is a driver failure.
Drivers act as a bridge between hardware and the operating system.
When a driver becomes corrupted, outdated, or incompatible, it can crash the system.⚠️ Which Drivers Usually Cause BSOD?
Some of the most common drivers responsible are:
✔️ Graphics Driver (Display issues)
✔️ Network/Wi-Fi Driver (Connectivity issues)
✔️ Storage / Disk Driver (Hard disk or SSD related)
✔️ Audio Driver
✔️ Antivirus / Security Drivers📌 How to Identify the Exact Driver?
BSOD often gives a clue in the form of a .sys file name, such as:
▪️nvlddmkm.sys → Graphics Driver
▪️rtwlane.sys → Wi-Fi Driver
▪️ntfs.sys → Disk/File System👉 This file name helps identify which driver is causing the crash.
💡 Key Takeaway:
A BSOD is not the actual problem it’s the system telling you that something at the driver or hardware level has failed.
In IT, the goal is not just to restart the system, but to find and fix the root cause.

Black screens on Windows 11 are primarily caused by faulty, outdated, or corrupted graphics drivers, failed Windows updates, or issues with display connections. To quickly fix it press Windows + Ctrl + Shift + B to reset the graphics driver (the screen may flicker briefly), or press Ctrl + Alt + Delete to open the security screen and select Restart from the power icon if the system is frozen but responsive.
1. Check physical connections: Turn off the PC and ensure HDMI, DisplayPort, or VGA cables are securely connected, trying a different port or monitor if possible.
2. Boot into Safe Mode: Restart the computer, hold Shift while clicking Restart on the login screen, then navigate to Troubleshoot > Advanced options > Startup Settings and press 4 to enter Safe Mode.
3. Update or rollback drivers: Once in Safe Mode, open Device Manager, expand Display adapters, right-click your graphics card, and select Update driver or Roll back driver.
4. Disable Fast Startup: Open Control Panel > Hardware and Sound > Power Options, click Choose what the power buttons do, select Change settings that are currently unavailable, and uncheck Turn on fast startup.
5. Repair system files: Open Command Prompt as administrator and run sfc /scannow, followed by DISM /Online /Cleanup-Image /RestoreHealth if the first command fails.
6. Uninstall recent updates: Go to Settings > Windows Update > Update history and uninstall the most recent update if the issue started after an update

Boot Configuration Data (BCD) is the firmware-independent database that stores boot-time configuration settings for Windows 11.
During the boot process:
1. Firmware (BIOS/UEFI) loads the Windows Boot Manager (BOOTMGR).
2. The Windows Boot Manager reads the BCD store to determine which operating system loader to execute and what boot parameters to use.
3. The BCD store contains entries with unique GUIDs, specifying the device location (partition), path to the OS loader (winload.exe), and boot options (like safe mode or debugging flags).
4. If multiple boot entries exist, the Boot Manager presents a menu for the user to select.
5. The selected entry launches winload.exe, which continues the startup process
For UEFI systems, the BCD store is typically located in the EFI System Partition (ESP) at \EFI\Microsoft\Boot\BCD. The Boot Manager uses standard UEFI APIs to locate it, falling back to the hardcoded path if needed. For BIOS systems, the BCD is located on the system partition at \Boot\BCD
To fix boot errors, boot from a Windows installation USB/DVD, select "Repair your computer," then use Command Prompt to run
Following commands, pressing Enter after each.bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcdOnce the operations are complete successfully, remove the USB/DVD and restart the computer.
