How To Remove Windows 7 Password - The Best Solution

Have you ever forgotten your login password on your computer?
Well, all of us experienced that, leaving your important files inside your computer.

In this tutorial, I will show you how to remove the password of your locked windows 7 computer.

This is what i believe the best method to solve this problem.

We're gonna replace your password with a new one.

This method, we are going to use different O.S or Operating System. In this case, we will use Ubuntu or any Linux Operating System. We are gonna use Ubuntu. You can download the latest version here. CLICK HERE You don't have to spend a single peso or cent because it's for free!

"So why are we need to use another Operating System?"
"We're going to use different O.S. to prevent conflict, because we are going to work on the windows system later. It's hard to explain, but the Window OS and Ubuntu is like Parallel lines, they never met."

Please select the proper O.S. that you are going to download, whether its 32 or 64 bit.

If you didn't know your system type, Click Start>> Right Click on "Computer" >>and Now click "Properties".
A window will pop up and you can see the type of your system.



Create a bootable Image, whether it's a usb installer or dvd/cd.
Now turn off your computer and boot from the usb or dvd you created.

Select, "Try Ubuntu". We don't need to Install it.

The reason why we run Ubuntu is we need to rename a file inside the Windows system32 which is the Windows OS system.




Navigate and find the hard disc drive where the Windows 7 is installed.
Go to this path folders: "Windows\System32 ".
Inside the System32 folder, find "osk.exe", now rename it as "1osk.exe". You ca actually rename it at any name, you decide, but better to just add one letter or number to become easy to be remember.

Again inside the System32 folder, find "cmd.exe", rename it as "osk.exe".

Now you can reboot your system.
You can go here for the part 2 >>

How To Remove Windows 7 Password - The Best Solution Part 2

This is the Part 2 and the Final Part

After you reboot to Windows 7, you are still lock.

On the logon screen, on the lower left corner, there's a small icon. Click that icon and a window will pop up.
Select or check, "On Screen Keyboard" click "Apply".
Amazingly, CMD will open instead of a Virtual Keyboard. That is the reason why we rename the cmd as osk.exe, to access the Command Prompt. ;-)





Now, on Command Prompt, Type "compmgmt.msc" and press Enter.






The Computer Management window will open.
Click "Local Users and Group" then click "Users".
On the right side, click the Account that you are going to unlock.
In my case, im going to unlock the "Rhai" account. I Click "Rhai".








On the right side, you will see "More Action" click it, and click "Set Password". See picture bellow.












A prompt will appear, just click "Proceed".

This window will appear and you can now set a new password for your locked computer!


Set and confirm your new password,
Click OK.

Congratulations! Your computer can now be access again! ;-)









THINGS TO REMEMBER:
Reboot your computer to Ubuntu again. You have to rename back the "osk.exe" to "cmd.exe" and "1osk.exe" to "osk.exe" to prevent encountering problems in the future.

Wind Generator - Ceiling Fan Turn Into Wind Mill

"GOD created the world & the rest was made in China!"- anonymous


Do you know a ceiling fan that is so cheap?...if you turn it on,
it starts crumbling or shaking like it was going to explode!



That ceiling fan is definitely made in china.

It has no control circuit inside and so dangerous to use,

it can burn you house if you left if turn on for a long time. To prevent the risk of danger of using it,

let's make it work on a different way.


I'm not new on generators and motors.
When i was a child I've been so interested to this matter. Here in my place in the Philippines,
We always having an electricity black out, it's going on and off when there's a strong wind.
That motivate me to dreamed of making my own electric generator for our home.
But due to my lack of knowledge(because I'm just a child then) I didn't finished any of my dream electric generator.

My uncle had one of this ceiling fan but it's wings are broken. I asked him to give it to me instead of throwing it to the junk.

I'm curios. I spin the fan and got electric shocked!
I discovered that it can produce
AC(Alternating Current) current when spinning.
I reversed engineer it and I figure it out.

It has a set of magnets around the magnetic wire
(coil), the magnet's setting was alternating poles
facing the coil, that's why it produces AC current.
What a great discovery?! L o L :D



OK. Here's how I turn it into a Windmill Electric Generator!

The tools and materials you need to this project are:

1. Soldering iron/ soldering wire.
2. Cutter
3. Some wire.
4. Electrical tape.
5. Some basic electrical knowledge :)
6. The cheap ceiling fan
7. Cheap re-chargeable flash light(optional)(china made)

Note, I will now call the ceiling fan as "fan" ;-)

Here's how I make it turn into a wind mill.

First. I make the wing of the fan. I don't have a PVC pipe as most people out there in the internet use a
PVC pipe as the wing of the windmill. On this project  I used a big thin bamboo from the backyard.
I tend to make the wing more thin  and lite weight for the fan to hold it easily.
I used a flattened PVC pipe and screw to mount the wing into the PVC. Refer to the pictures below.



Before we mount the wings, we're gonna work on the electronics and parts first.


Now, cut the plug of the fan and peel the outer rubber of the wire,
revealing the copper wire inside. We have now an access to the wire where we can
connect the charger(a.k.a charge controller) of our windmill.

We don't need to change anything inside of the fan because it was already
a wind mill generator just disguising as a fan! hehehe.

Remove this part of the fan.

















The electronics. Instead of buying expensive charge controller, I use this simple circuit.
I have a broken re-chargeable flashlight(actually its made in china again). We will use the the charger circuit as the charge controller.

 Remember where the Input and Output comes from the circuit board.
Solder the the wires from the fan. Also solder two wire for the output.












I assemble a case out of a rubber sheet for the battery and the controller to make it safe.
I also put a switch to turn the charger on and off.
Figure out the polarity by using a multitester while spinning the fan.

I put a high capacity 3.6 v Ni-cad battery from an old laptop battery pack.

The battery Inside the case is fix there. So I connect wires to the
positive and negative of the battery and put a usb port as the output where we
can connect a load. Most likely, I use the battery to my night light in my room.













This is the finished case, I make
additional output connection of the
charger.












I used bamboo for the body and plywood for the tail.
We can now put the wings and it's ready to fly! :D





The magnetic wire inside is so thin that's why it produces high voltage but low current.
You can modify it. Replace it with thicker magnetic wire
to increase the current production.

Sorry for my English, I've try my best. :-)
