I put a password on my son's computer and can't remember it. He is the only user on it. How can I remove it

Answer 1

Help with a lost Windows password
Windows includes a hidden Administrator account that can be used for problems with other accounts. You can access it by restarting the computer into safe mode.
First, restart the computer. As it starts, repeatedly press the F8 key (some computers instead require the Delete or Esc key). Instead of the familiar Windows screen, you'll see a text-only Advanced Options Menu. Use the arrow keys to select Safe Mode. Then press Enter.
Select the Administrator account. By default on most computers, it requires no password. Once logged in, you can change the password of the account you normally use.
To make the change, click Start>>Run. In the box, type "control userpasswords2" (without the quotes) and click OK. Select your normal account name in the list. Click the Reset Password button. You'll be prompted for a new password. You can restart the computer and use the new password on your normal account.
If you're completely locked out of your computer, you'll need software. Such services include Login Recovery, FastCrack, and NT Password and Registry Editor. Each is free. They make use of boot disks that you can download to a floppy or burn to CD. Of course, you'll have to use some other computer to do the downloading.
Once you've got access to your computer, set a new password through Windows. To do it, click Start>>Control Panel. Double-click User Accounts. Select your account and click "Change my password." You'll be prompted for a new password.
You'll also have the opportunity to enter a password reminder. It should trigger your memory if you ever forget your password. But the reminder should not be descriptive enough to allow others to determine your password.

The following steps will remove any password set in the Internet Explorer Content Advisor and allow you to reset the program to its original state.
1) Click on Start and choose Run.

2) Type in RegEdit and select OK.

3) Now click on the little plus sign to the left of H_KEY_LOCAL_MACHINE.

4) Continue to drill down, always clicking on the plus sign at the left of the named key, through Software, Microsoft, Windows, Current Version and Policies.

5) Now click on the Ratings folder
In the right pane of the RegEdit window, you'll see an icon called Key. Click on it and press Delete.

7) Next, choose Registry and then Exit to exit RegEdit. You've just deleted your original Content Advisor password.

8) Restart the computer and run Internet Explorer again.

9) Choose View and then Internet Options (or Options for version 3.x). For IE 5 or greater, Click on Tools, Internet Options.

10) Click on the Content tab and click on Disable. When asked for a password, don't enter anything; just click on OK. This will disable Content Advisor because there's no longer a password.

Answer 3

If you are refering to the password on the Windows, you can format the system and reinstall the OS. If you are refering to the BIOS password on your start up, you can call your computer vendor. The most easy way is get the password from the person whom set it.

Answer 4

If it's Windows, press f8 a few times when the machine is starting up and select "safe mode"

From the resulting Windows startup, you should be able to log in as administrator and reset the password.
