How to use PCUnlocker
Step 1: Create a bootable CD/DVD or USB flash drive
Download the PCUnlocker and save it on any computer you have access to. Unzip the downloaded file, there should be an ISO image file: pcunlocker.iso. You can use the BurnCDCC program to burn the ISO image to a blank CD/DVD, or burn it to a USB flash drive using ISO2Disc.
Step 2: Set BIOS to boot from CD/DVD or USB flash drive
Boot your locked computer. When it is powered on, check the boot-screen for setup key (i.e. DELETE key, F8 key, F2 key) to enter BIOS Setup Utility.
Choose the BOOT menu and set Boot Device Priority option: Set the 1st Boot Device to CD/DVD-ROM if what you created is a bootable CD/DVD, or set the 1st Boot Device to Removable Device for booting from USB flash drive. Press F10 to save your changes.
Step 3: Boot Your Computer from CD/DVD or USB drive
Insert the newly burned CD/DVD or USB flash drive on your locked computer and restart the computer. The boot loading screen should appear immediately.
After completion of boot process, you see the main window of PCUnlocker.
Step 4: Reset Windows Password
Reset Local Admin/User Password: Select your Windows SAM registry file, the program will automatically list all user accounts. Select a user account and click the Reset Password button to reset the password to blank.
Reset Active Directory Password (For domain controller only): Select your Windows Active Directory database (ntds.dit) file, the program will automatically list all domain accounts. Select a user account and click the Reset Password button to change the password to Password123.
Click the Restart button and take out the password reset disk. Restart your computer, you'll find you can get into the computer directly without being asked for password.
