Can’t Log On to Windows XP?*
If thats your only problem, then you probably have nothing to worry about. As long as you have your Windows XP CD, you can get back into your system using a simple but effective method made possible by a little known access hole in Windows XP. This method is easy enough for newbies to follow. It doesnt require using the Recovery Console or any complicated commands. And its free. Your sole problem is the inability to logon to Windows due to a forgotten password. Heres how to solve this using the Repair function of xp cd with a step-by-step description of the initial Repair process included for newbies.
Place your Windows XP CD in your cd-rom and start your computer (its assumed here that your XP CD is bootable ïž– as it should be - and that you have your bios set to boot from CD)
2. Keep your eye on the screen messages for booting to your cd Typically, it will be ïž“Press any key to boot from cdïž” 3. Once you get in, the first screen will indicate that Setup is inspecting your system and loading files. 4. When you get to the **Welcome to Setup** screen, **press ENTER to Setup Windows now** 5. The **Licensing Agreement** comes next - Press** F8** to accept it. 6. The next screen is the **Setup** screen which gives you the option to do a Repair. It should read something like ïž“If one of the following Windows XP installations is damaged, Setup can try to repair itïž” Use the up and down arrow keys to **select your XP installation** (if you only have one, it should already be selected) and **press R to begin the Repair process.** 7. Let the Repair run. Setup will now check your disks and then start copying files which can take several minutes. 8. Shortly after the Copying Files stage, you will be required to reboot. (this will happen automatically ïž– you will see a progress bar stating ïž“Your computer will reboot in 15 secondsïž” 9. During the reboot, do not make the mistake of ïž“pressing any keyïž” to boot from the CD again! Setup will resume automatically with the standard billboard screens and you will notice **Installing Windows** is highlighted. 10. Keep your eye on the lower left hand side of the screen and when you see the **Installing Devices** progress bar, press **SHIFT + F10**. This is the security hole! A command console will now open up giving you the potential for wide access to your system. 11. At the prompt, type **NUSRMGR.CPL** and **press Enter**. Voila! You have just gained graphical access to your **User Accounts** in the Control Panel. 12. Now simply pick the account you need to change and remove or change your password as you prefer. If you want to log on without having to enter your new password, you can type **control userpasswords2** at the prompt and choose to log on without being asked for password. After youïž’ve made your changes close the windows, exit the command box and continue on with the Repair (have your Product key handy). 13. Once the Repair is done, you will be able to log on with your new password (or without a password if you chose not to use one or if you chose not to be asked for a password). Your programs and personalized settings should remain intact.
I tested the above on Windows XP Pro with and without SP1 and also used this method in a real situation where someone could not remember their password and it worked like a charm to fix the problem. This security hole allows access to more than just user accounts. You can also access the Registry and Policy Editor, for example. And its gui access with mouse control. Of course, a Product Key will be needed to continue with the Repair after making the changes, but for anyone intent on gaining access to your system, this would be no problem.
And in case you are wondering, NO, you cannot cancel install after making the changes and expect to logon with your new password.
Cancelling will just result in Setup resuming at bootup and your changes will be lost.
Ok, now that your logon problem is fixed, you should make a point to prevent it from ever happening again by creating a **Password Reset Disk**. This is a floppy disk you can use in the event you ever forget your log on password. It allows you to set a new password.
Here's how to create one if your computer is NOT on a domain:
-
Go to the Control Panel and open up User Accounts.
-
Choose your account (under Pick An Account to Change) and under Related Tasks, click “Prevent a forgotten password”.
-
This will initiate a wizard.
-
Click Next and then insert a blank formatted floppy disk into your A: drive.
-
Click Next and enter your logon password in the password box.
-
Click Next to begin the creation of your Password disk.
-
Once completed, label and save the disk to a safe place
How to Log on to your PC Using Your Password Reset DiskStart your computer and at the logon screen, click your user name and leave the password box blank or just type in anything. This will bring up a Logon Failure box and you will then see the option to use your Password Reset disk to create a new password. Click it which will initiate the Password Reset wizard. Insert your password reset disk into your floppy drive and follow the wizard which will let you choose a new password to use for your account. Note: If your computer is part of a domain, the procedure for creating a password disk is different.
