I have test this tool can reset password Administrator and also other account on local system on Windows XP and 2003 Server R2.

Step-by-step to reset administrator password
- I recommend you to review all steps before you configure on real system. In this example, I’m going to reset password Administrator on Windows 2003 Server R2 which was installed on first IDE drive(c:\).
- Download EBCD (Emergency Boot CD-ROM) from ebcd-0_6_1-pro-sfx
- Extract and run makeebcd.exe. It will automatically create image file (EBCD061P.ISO) for burning to CD.
- Burn the file in step 2) to CD.
- Boot the computer with CD that youâ€™ve just created. You will see the menu as the figure below. Select (5) NT password for editor (Linux-based) by type ‘5’ (with on quote) and press Enter.
- Press Enter to continue.
- Press Enter again if you don’t keep Windows on SCSI drive or type ‘y’ if you want to load SCSI driver.
- Now select which partition(drive) that contains Windows system. You can press Enter without answer to accept the default value in bracket . In this step, the default value is [/dev/hda1]. This is partition in Linux format but you can ignore the detail if you have Windows on C: which is the most cases.
- Press Enter again to accept value in bracket again.
- Press Enter.
- Now, it’ll show the change NT password menu. Press Enter to accept value in bracket  (Edit user data and passwords).

Note: I have tried set some password(not blanking) in this step but the password wouldn’t work when log in but the blank password works fine.
- It will ask your confirmation. Type ‘y’ (without quotes) and press Enter to confirm your changes.
