Get Windows administrator privileges
A few days ago, I ran to meet when I didn't have a lock computer keyboard, and I came back to see the IT department sitting in me. I changed my administrator account password. Very sad, I feel that I am crossing a bar with my computer, the computer turns into a cold machine. I want to want to go, I don't want to give up the original feel. So I want to find a software to calculate the way to crack. Search for online search, a search is a few hours, too time. But I know some things below. WindowsXP's password is stored in the WinNT / System32 / Config under the system, the SAM file is the account password database file. When we log in to the system, the system will automatically use the SAM automatic school pair in config. If this password and the username are compliant with the encrypted data in the SAM file, you will be able to log in smoothly; if the error is not logged in.
At the end, I tried several hacker software, and I didn't find how to crack the way I didn't have a floppy drive, there was no machine. Only I have to delete the SAM file home from the hard disk to let the administrator account is empty.
Below is a good article:
XP administrator password recovery Five Tips Date: 2004-7-13 20:10:37 Source: Author: all-powerful sentiment: Today: 5 Week: 74 Month: 32 Total Views: 76 ________________________________________ Tip 1: As you know, WindowsXP's password is stored in the WinNT / System32 / Config under the system, the SAM file is the account password database file. When we log in to the system, the system will automatically use the SAM automatic school pair in config. If this password and the username are compliant with the encrypted data in the SAM file, you will be able to log in smoothly; if the error is not logged in. In this case, our first method will produce: delete the SAM file to recover passwords.
If you don't have to include any account contained in the system card, and there are two operating systems, you can use another operating system that can access NTFS to start your computer, or although there is no two systems, you can use other tools to access NTFS. Then delete the SAM file under the C: / WinNT / System32 / Config directory, restart. At this time, the administrator administrator account has no password. Of course, remove the hard disk to other machines to delete SAM files.
Tip: WINDOWSNT / 2000 / XP The security management of the user account uses the mechanism of the security account manager (SAM), the security account manager is created by the security ID, the security identifier is created by the security ID. Create at the same time, once the account is deleted, the security ID is also deleted at the same time. The security logo is the only one, even the same username, the security ID obtained at each creation is completely different. Therefore, once an account is deleted, its security ID will no longer exist, even if the same username rebesses the account, it will also be given different security ID, and the original permissions will not be retained.
The specific performance of the Security Account Manager is the% SystemRoot% / System32 / Config / SAM file. The SAM file is the user account database of WindowsNT / 2000 / XP, and all users' login names and passwords are saved in this file.
Tips 2: The following describes a relatively different ways. You can load an XP in other partitions, the hard disk partition format is the same as the original, and please pay attention to the same partition with the original XP! Before you start, you must back up the boot area MBR (Master Boot " RECORD. There are many ways to back up MBR, you can program themselves, or use tool software, such as anti-virus software KV3000, etc. After loading, log in with administrator, now you have absolute write permissions to the original XP. You can copy the original SAM and get the original password with Lophtcrack. You can also override all the files of the newly installed XP Winnt / System32 / Config to the C / WinNT / System32 / Config directory (assuming the original XP is installed here), then use KV3000 to restore the previous backup of the main boot area MBR Now you can use administrator to log in to the previous XP. Tip: MBR commonly known as "main guidance zone", its role is to read the active partition set in the disk partition table (partition table), located on the hard disk, head 0, sector 1 Location, you also know your 0 track position. It is generated by the partition command fdisk. MBR includes two parts of the hard disk boot program and partition table. The MBR end sign is 55AA, which can be viewed with the F6 function of the anti-virus software KV3000, and its default picture is MBR. If MBR can't find an active partition, it will display an error message like Missing Operating System on the screen, so if your WindowsXP cannot be turned normally. And you see a wrong message like this on the screen, which is mostly here. Tips 3: Use off1ine nt password & registry editor. With this software to make a Linux boot disk, this boot disk can access the NTFS file system, so you can support Windows2000 / XP well. Use a tool NTPasswd running in Linux in this floppy disk to solve the problem. And you can read the registry and rewrite the account password. The method used is simple, just step by step according to its prompts, you can do it step by step. Here, I suggest you use a quick mode, which will list the password for users to choose which user who modifies. By default, the user of the Admin Group is selected, which automatically finds users who replace the name of the Administrator, which is very convenient.
Tips 4: Use Windows Key 5.0. The software is included in Passwarekit 5.0 for recovering the password of the system administrator. After running, 3 files are generated: txtsetup.oem.winkey.sys and winkey.inf, 3 files are only 50KB, short and delicate. Put these three files in any floppy disk, then use the XP installation CD to boot your computer, press F6 key during startup to allow your system to install third-party drivers. At this point, it is the best time we cut, and the floppy disk will automatically jump to the interface of WindowsKey. It will force the password of the Administrator to "12345". What is the big event? Oh! When you restart, you will be asked to modify your password again.
