Add Disk Defrag, Check Disk and Disk Cleanup to Disk Context menu

 Check Disk (CHKDSK) is a Windows tool that scans your drive for file system errors and bad sectors, and can repair them when run with the right parameters.

CHKDSK examines the file system integrity of a disk and can fix logical errors or mark damaged sectors so they aren’t used again. It can help with issues like slow performance, corrupted files, crashes, or boot errors.

Open your registry editor (regedit.exe) and go to HKEY_CLASSES_ROOT\drive\shell

Create the following:

HKEY_CLASSES_ROOT\Drive\shell\Launch Disk Clean-up\command

Put (default) = cleanmgr.exe /d %1

HKEY_CLASSES_ROOT\Drive\shell\Launch Disk Defrag\command

Put (Default) = C:\Windows\System32\defrag.exe %1

HKEY_CLASSES_ROOT\Drive\shell\Launch Check Disk\command

Put (Default) = C:\Windows\System32\chkdsk /r /f %1

Definitions

Disk defrag is a program designed to increase the speed of accessing the files by rearranging them. The main purpose is to optimise the time it takes to read and write from the disk.

It improves startup times and many more.

Defrag.exe offers more options and control for defragmentation process such as performing a full defragmentation and many more.

CHKDSK is a command Line disk tool that verifies the integrity of your file system structure and the hard disk drive.

Disk Cleanup (cleanmgr.exe) is a maintenance utility designed to free up disk space and remove unnecessary files.

Enjoy!

Coded Old Inverter Technology

 

Heres a quick theory, when you input X pulses to a transformer, It will have an output of 2X Sinusoidally. We use CB One, instead of 555 or CMOS IC... NEW Power Technology??

Registered Users at Windows

 

Windows user accounts let multiple people share a computer with private files, apps, and settings, or allow you to separate work from personal tasks. You can manage them through the Microsoft Support User Management Guide.

Types of User Accounts

Administrator: Has complete, full control over the computer, including installing software and changing system-wide settings.
Standard User: Can use installed apps, browse the web, and save personal files, but cannot change core system settings or install software that affects other users.
Local vs. Microsoft Account: A Microsoft account links your login to cloud services, email, and settings sync across devices, whereas a local account stays offline and strictly tied to that specific PC.

Quick Ways to View All Accounts on a PC

 Using netplwiz: Press Windows + R, type netplwiz, and hit Enter to open the classic User Accounts panel.

 Using Settings: Go to Settings > Accounts > Other users to see a full roster of non-admin or secondary profiles.

How to Switch Between User Accounts

• From the Start Menu: Click the Start button, select your profile icon at the bottom (or side), and choose another user account from the list.

• From the Lock Screen: Press Windows + L to lock your PC, then select the desired user profile at the bottom-left corner of the screen and enter their password.

How to View and see the List of users using Commant Prompt

Control Engineering

Control Engineer (or controls and automation engineer) is an engineering specialist who designs, develops, installs, and maintains dynamic systems and automated equipment. They act as the bridge between physical machinery and digital intelligence, ensuring that industrial and mechanical processes run safely, efficiently, and with high precision.

Electronics Engineering

a branch of electrical engineering that focuses on designing, developing, and testing small-scale circuits, microchips, and semiconductor devices to process and communicate information rather than distribute heavy power.

Electrical Engineering

They designs, develops, tests, and supervises the manufacturing and installation of electrical equipment, components, and systems—ranging from small microchips to massive power grids.

Mechanical Engineering

Mechanical engineer designs, develops, builds, and tests mechanical and thermal devices, machines, and systems.

Civil Engineering

A civil engineer is a professional who plans, designs, builds, operates, and maintains public and private infrastructure—such as roads, bridges, dams, water systems, and buildings—while protecting public and environmental health.

Computer Engineering

A computer engineer combines electrical engineering and computer science to design, develop, and test computer hardware and software systems

Show How much RAM is Installed

RAM (Random Access Memory) is a type of short-term, high-speed computer memory that temporarily stores active data, running applications, and the operating system your CPU is using right now.

How?

1. At Run Window, type: control /name Microsoft.system

2. Using cmd.exe, type: systeminfo

How RAM Works

Volatile Storage: RAM loses all its stored data the moment you turn off or restart your device (unlike long-term storage drives like SSDs or HDDs).

Direct CPU Access: The processor can read and write data in RAM in any order at lightning-fast speeds, making multitasking and app loading smooth.

The "Desk" Analogy: Think of RAM like a physical desk. A bigger desk (more GB) lets you spread out more papers and tools (open apps) at the same time without clutter or slowdowns.

Main Types of RAM

DRAM (Dynamic RAM): Used for main computer and phone memory; it needs constant electrical refreshes to keep data. Modern systems typically use DDR4 or DDR5 SDRAM.

SRAM (Static RAM): Faster and more expensive; used for small, ultra-fast CPU cache memory because it does not need refreshing as long as power is supplied.

How Much RAM Do You Need?

> 4 GB to 8 GB: Basic web browsing, schoolwork, and light office tasks.

> 16 GB: General multitasking, moderate gaming, and daily productivity.

> 32 GB to 64 GB+: Heavy gaming, 4K video editing, 3D rendering, and professional content creation.
