Funny enough many still forget their Microsoft windows password despite the easy password recovery disk creation already provided in later versions of the windows like windows vista , windows 7 , windows 8 and are only stacked at the welcome /log on screen .
Just yesterday I decided to try out some of the old tricks I usually use in previous versions like the archaic ctrl+alt+delete + administrator , the net user , the windows bootcd and even the almighty ophcrack made me run outta patience ‘cos I couldn’t wait for it to finish the whole calculation .
So I decided to try out offline nt password and it worked like I expected same story could as well go for pc login now .
Just download the iso file from the links provided above and use a boot-able image creator like cyberlink power 2go , alcohol 120%, ashampoo burning rom , nero creator or roxio burning suit to burn it to a blank cd .
Then set your system bios to boot from cd rom , it will boot on to the Linux like window on restart , from there you can clear the user / administrator password you wanna log in to .
