(Regarding the headache of forgetting the password of the laptop, sometimes the CMOS discharge does not work. At this time, you can use this software, do not enter the system, but operate on other computers! If you think it's good, give me a good review, because this software was found on foreign websites, and it took a lot of genius to find it, but you can't download it on Baidu. . . . . This software HP and other official password cracking software!)
