The ZIP package contains ISO image with 'Reset Windows Password' utility
and a special tool for creating bootable disks.

1. Unpack the archive to your hard disk, run IsoBurner.exe, select an item
   for creating bootable CD/USB and browse for the unpacked ISO image file.
   Proceed to the next Wizard step and write the ISO image to disk.

2. When making a bootable USB drive, keep in mind that  depending  on  your
   target PC's type, you should  select  either  BIOS-  or  UEFI-compatible
   partition scheme. Use 'Max possible compatibility' scheme  if  you  know
   nothing about the target PC. This mode allows creating drives  that  can
   be booted in both BIOS and UEFI CSM modes.

3. Insert the newly created bootable CD/DVD or USB into  your  problem  PC,
   reboot it and change its BIOS/UEFI settings  to  make  the  boot  device
   (CD-ROM, DVD-ROM or USB disk) first on the list. Save the BIOS settings,
   reboot once again and launch 'Reset Windows Password' from your bootable
   media. Some BIOS/UEFI have fast boot menu, typically called  by  hitting
   F8 key during startup.
