Creating users on a computer using command prompt

Admin — Sun, 01 Sep 2013 16:42:49 GMT

User account creation on a computer is very simple task. As we all know, we just go to Control panel >User Accounts and create new user and set password etc. Nothing is so different right? but it could be more easy when it comes to create multiple users on a computer. We can use command prompt to save our time. I faced this problem before. I was in an institute and there were several computers, The task that was assigned to me was that I had a list of 50 students with their usernames and passwords. I had to create user account of each student on each computer. There were almost 58 computers. If I multiply, it is 58 x50 = 2900 accounts.

Would you try to go to Control panel each time and create a new user??? Never. It will take a lot of time. So, I'll tell you which command I used to save my time.

Step1: Click on Start, go to RUN and Open Command prompt

Step2: Type this command: net user username password /ADD

Since, I had a list of usernames and passwords, I simply replaced the text of command with actual username and password using text-pad and ran the command on all computers one by one. It actually saved my time.

To add the user accounts on domain, you can use: net user username password /ADD /DOMAIN


If you know DOS commands, this could be added to your knowledge.

How to know the manufacturing date of a computer?

Admin — Sun, 01 Sep 2013 16:03:08 GMT

Most of people prefer to buy new computer from a brand or probably get them assembled as per configuration. Yesterday, one of my friends bought an old computer at very low cost. He told me that it was 10 months old. A very quick question that came in brain was that there should be any option to know the manufacturing date of computer. I tried several commands and finally found one very correct.

(Note: It works on Windows computers)

Let me tell you about how it works:

1. Click Start button > Open Run and type CMD to open command prompt.

2. At command prompt, type debug and press enter.

3. At the next line type DF000:FFF5 and again press enter

The manufacturing date of your computer will come at the right side as shown in the image below.

To know the manufacturer of your computer, use this command: wmic csproduct get vendor, version

If the above command doesn't work, then try this:

wmic computersystem get model,name,manufacturer,systemtype

How to see hidden data on Pendrive?

Admin — Mon, 26 Aug 2013 12:48:41 GMT

Yesterday, I was helping one of my friends with his computer. Once I speed up his computer, he put a strange thing in front of me. He plugged his 8 GB pen drive in to his computer. I moved to "My Computer" and found that there was data of size 2 GB in the pen drive as displayed on its drive Icon.

When I opened the pen drive, it was empty. He also told me that he surfed many websites/forums and found that there were many people facing the same problem but there was no exact working resolution. Some people suggested to format the pen drive, some suggested that the pen drive's hardware has problem but I feel them like fake posts as those were not helping people. My friend had to give exams next day and the data in pen drive was very very important for him. There was no need to format the drive. So, I finally thought to share it on my website to help people.

You may be laughing as this could be that the folders were hidden. So, I took the initial steps to resolve this problem.

Step 1: I moved to control panel and opened "Folder Options"

Step 2: In "Folder Options" under "View", I clicked "Show hidden files, folders and drives".

I was surprised that the data was still not visible in the pen drive. Finally, I ran my hands on command prompt and found a command.

This command works when your pen drive's data is not visible: attrib -h -r -s /s /d h:\*.*

In the command above, h: is the pen drive letter. When you plug your pen drive into your system then this letter could be different. All you have to do is change this letter accordingly in the command.

I'm sure, this will help many other people who are facing the same issue with their pen drives.

Have a great time!!

Gravity and Atmosphere

Admin — Sun, 11 Aug 2013 11:40:42 GMT

Gravity is the force of the Earth attracts every object towards itself. From our perspective this force always acts downwards. For a long time people did not believe that the Earth is round because then the people 'underneath' the sphere would have actually fallen down. In 1687, a physicist, Isaac Newton, proved that the force of gravity always acts towards the center of the Earth. On the Earth, the force of gravitation always acts downwards irrespective of Eskimos in the Arctic region, people in Europe or inhabitants of Australia.

There is a direct relationship between gravitational acceleration and the downwards weight force experienced by objects on Earth, given by the equation F = ma (force = mass × acceleration). However, other factors such as the rotation of the Earth also contribute to the net acceleration.

The word ‘atmosphere’ means a gaseous cover enveloping a planet. Without atmosphere life would not have been possible on the Earth: One-fifth of the atmosphere is oxygen and four-fifths is nitrogen. Like the Earth’s interior, the atmosphere too is made up of several layers. All animals and plants live in the lowermost layer of the atmosphere called the’ troposphere; All weather phenomena take place in the troposphere. Even Aeroplanes fly in the outer edge of the troposphere. The stratosphere, the mesosphere, the ionosphere, and the exosphere lie above the troposphere.

How do we discover inside the Earth?

Admin — Sun, 11 Aug 2013 08:54:24 GMT

The Continental Deep Drilling, near the Bavarian city of Weiden,
drilled a hole around 9 KM deep in an old mountain. The drilling rig
was over 80 m high.

Caves and mines go only up to 1-2 km inside the Earth. the deepest wells of the world, such as the one 12 km deep in the Russian Kola Peninsula or the 9-km-deep one in the Upper Palatinate, hardly scratch the Earth's crust. One can 'look' deep inside the Earth in the aftermath of earthquakes or creating nuclear explosions. the explosions generate sound or seismic waves. They also throw off rock particle. By measuring their intensity and timings, scientists discover the composition of the Earth's interiors.

(Did you know that)

More than 2200 years ago, the Greek discovered that the Earth is round. They even calculated an almost circumference of the Earth
The Earth is not a perfect globe. It's circumference at the equator is 40,077 KM whereas measured over the poles, it is 68 KM less
'Atmosphere' is a Greek word which means 'ball of vapour'

About 3000 ago people believed that the Earth was flat. But people wondered why ships disappeared at the horizon. Sailors too returned from journeys and were proof that ships did not fall off the edge of the Earth. The simplest explanation was: the Earth must be round. The final proof came in the year 1522 after the expedition of Ferdinand Magellan, who was the first to sail around the Earth.

External and Internal Structure of Earth

Admin — Sun, 11 Aug 2013 08:34:25 GMT

It has been known for more than 2000 years that the Earth is round, but we were able to actually see this much later only when we flew into space. The knowledge why we do not fall off from the Earth is much more recent. A journey as described by author Jules Verne in his book Journey to the Center of the Earth was, after all, impossible. Only one thing was known: the Earth is made up of soil, rocks, and water. Today, we know that the Earth is also surrounded by an air cover the atmosphere.

Like an onion the Earth has several layers. The outermost layer, the Earth’s crust, has an average depth of about 40 km. As compared with the diameter of the Earth, which is around 12,700 km, the Earth’s is very small. it is primarily made up of solid rocks. Below the crust is the mantel, reaching to a depth of about 2900 km. Due to the heat inside the Earth ,the mantle consists of solid and molten rocks. Below the mantle is the core, made up of iron and nickel. The deeper one travels inside the Earth, the hotter it is. The temperature in the core is between 4000 and 5000 degree Celsius.

Make your computer speak your words

Admin — Sun, 11 Aug 2013 07:33:02 GMT

Yesterday, I was exploring my computer to find new things. I have Windows7 installed. Unfortunately, my mouse was not working, so I tried to use Speech Recognition feature of Windows 7 and instructed my computer to do what I wanted. This was working perfectly fine. Then I thought to read VB Script for about an hour and tried to create a small script that allows your computer to speak the words you type. Let's see, how that script works:

Step 1: At first, open notepad(Obviously, it's a script editor)

Step 2: Copy the code below and paste that into the notepad file

createobject("SAPI.SPvoice").speak "Type your words here"

Step 3: You can type anything instead of "Type your words here" above and make sure quotes are still there

Step 4: Save the file with extension .vbs ; For example, if your file name is test then save it as test.vbs

You can then run the file and you will hear the words you typed.

How 3-D PC Glasses Work?

Admin — Mon, 05 Aug 2013 12:26:20 GMT

We watch 3 D movies these days. NVIDIA launched his 3 D vision glasses to provide you ultimate 3 D media experience. We use 3 D PC glasses for that. A 3D or 3-D film or S 3D stereoscopic 3 D film is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a regular motion picture camera system is used to record the images as seen from two perspectives and special projection hardware and/or eye wear are used to provide the illusion of depth when viewing the film.
