How to crack windows nt administrator password . How to access your PC if you forgot your Windows password ...Edit Article wikiHow to Log on to Windows XP Using the Default Blank Administrator Password Community Q&A Here is a simple way to access Windows XP with Administrator rights and privileges if you have password protected your User account on your Windows XP system and can t remember the password(s) to login. Whenever Windows XP is installed on a system, it creates a default account called Administrator and by default this account is not password protected. Therefore, if you bought a brand name computer (such as Dell, HP, Compaq or Sony)or you have installed Windows XP yourself. You should be able to login to the computer through the unprotected Administrator account.
When you installed Windows XP (or when the people who sold you the computer installed it), it created an administrative account automatically. This account has NO password by default, and can be used to access everything in the computer. By accessing it, you can change any password on the system. Click through several self-explanatory screens until your reach the familiar Welcome screen.
Note that this welcome screen is limited to 256 colors and 640x480 resolution because the primary graphics will have been set to the Windows Safe Mode software VGA adapter. You will not be able to change this mode even in Display options, while Windows is running in Safe Mode. Open up the command shell.
Press START, click RUN, and type in CMD, press ENTER. This will bring up a window likely unfamiliar to you. This is the command line, it allows you to manage files or change settings without restriction (no restriction on the administrative account). Before the graphical environment of Windows, this is what Microsoft users used.
Change the password of the account. Type in (without the quotes, and yes, the asterisk (*) is necessary) net user (username) *. It will ask you to type in a password, then to retype it.
You just changed the password! Log in. Exit the command shell dialogue, don t type in anything else if you don t know what you re doing, you could really hose down your computer. Log out of the administrative account, then log back in to your account with the new password. A much simpler method is simply to rename or delete the SAM file (renaming is safer).
For this you need to boot the box using some other operating system on a CD and then mount the drive (otherwise Windows locks the SAM file and won t let you touch it). NTFSDOS is also a good utility for this purpose. Find the SAM file and change the first character. After you reboot, all the accounts are still there, but they all have null passwords. Note: if you rename the SAM file on XP SP2, when you reboot, XP fails to initialize and forces you to reboot in safe mode. However when you boot into safe mode you get the same message, so don t try this method on XP SP2.
You can access the Administrator account through the login prompt without logging into safe mode. If the computer utilizes the welcome screen instead of the standard NT domain login prompt, you can press Ctrl + Alt + Del twice to get to the login prompt. This is only true if you are running Windows XP Professional Edition. Windows XP Home Edition will also allow you to use this method to log on. The SysInternals ERD Commander product used to change the admin password seems to have been discontinued, however there are many other options out there for resetting the password so long as you are willing to spend a little money. Boot from the CD and select the locksmith option to change whatever password you like.
There is a way to crack the windows SAM and system files. To retrieve the original passwords Monitor, you need a program such as LC5 installed on a computer, and the SAM file in C:\WINDOWS\system32\config. If LC5 is not installed on the computer that you forgot to, you need to install it with a disk through DOS, not Windows, because as soon as the hard drive starts windows it is using the file so you can t copy it.
Some users are smart enough to password protect their Administrator account when they install windows. If that s the case, you ll have to know that password in order for this method to work. This whole process is pointless if you know the administrator s password as you can easily remove passwords without going into safe mode. Assuming that your PC only has one user profile with administrative powers. You must own the computer and be licensed to use the operating system.
You must also have Administrative rights to the entire library of information on the disk. Otherwise accessing Windows Administrator and changing passwords could be construed as illegal entry and electronic trespass in a court of law. Use these instructions for ethical purposes only, please. This method may or may not work with machines running XP SP2, you will need to use safe mode with networking instead.

Does this account still exist, and how can you access it?
The account is created in Windows 10, 8, 7, or Vista, but since it’s not enabled you can’t use it. If you are troubleshooting something that needs to run as administrator, you can enable it with a simple command. Note: You really shouldn’t use this account for anything other than troubleshooting. In fact, you probably shouldn’t use it at all. Enable Built-in Administrator Account in Windows First you’ll need to open a command prompt in administrator mode by right-clicking and choosing “Run as administrator” (or use the Ctrl+Shift+Enter shortcut from the search box).
Note that this works the same in all versions of Windows. Just search for cmd and then right-click on the command prompt icon in the Start menu or Start screen. If you are in Windows 8.x or 10 you can right-click on the Start button and choose to open a command prompt that way.
Now type the following command: net user administrator /active:yes You should see a message that the command completed successfully. Log out, and you’ll now see the Administrator account as a choice. (Note that this screenshot is from Vista, but this works on Windows 7 and Windows 8 and Windows 10) You’ll note that there’s no password for this account, so if you want to leave it enabled you should change the password. Disable Built-in Administrator Account Make sure you are logged on as your regular user account, and then open an administrator mode command prompt as above. Type the following command: net user administrator /active:no The administrator account will now be disabled, and shouldn’t show up on the login screen anymore. What is the difference between the Administrator Account and the regular account?
I guess what I’m trying to say is: what can administrator account do that regular account (with UAC turned off) can’t do? “Isn’t this a potential major flaw?” No. If i remember then somebody has to set a password for the Administrator user when they first install Vista. On some OEM versions I think the Administrator password is automatically set to the password of the initial user. I do not think guest accounts can run UAC because they are not users that can run it. What is the difference between the Administrator Account and the regular account?
I guess what I’m trying to say is: what can administrator account do that regular account (with UAC turned off) can’t do? Probably nothing, but I’d rather get there through legitimate system options than registry hacks, which is the only method I’ve seen for disabling UAC. On some OEM versions I think the Administrator password is automatically set to the password of the initial user. So what happens with all the people who get a new Vista machine and don’t bother to set a logon password? Probably nothing, but I’d rather get there through legitimate system options than registry hacks, which is the only method I’ve seen for disabling UAC.
I disable UAC all the time without registry hacks. I thought there was an option in control panel somewhere… administrator password can be changed from command prompt as far as i know: type: net user administrator * then it asks for the new password, a confirmation of the new password then says comand completed successfully. well, when I go to the command prompt, it defaults to “C:\USERS\[username]>” and I cannot use the command. The system response is : “System error 5 has occurred” “Access denied” I do not have an administrator log on icon at start up and there is no file for it when I use “Start” “Explore” did I delete the administrator user account or something? How do I fix it? Thanks!
This link may help explain some of the security issues for above comments, though it’s for mapped drive access: http://support.microsoft.com/kb/947235 If you don’t really need to do this, I’d suggest that you don’t. Security is a tough thing to manage. I suspect that if you follow the registry edits at the link, then you’ll be able to change the Administrator’s password using “net user administrator *” I also don’t have a user file structure for Administrator and it doesn’t show in the user list, but it’s there.
From the command prompt just type “net user” and Enter. To make it show up during startup I think you can type “net user administrator /active:yes” and Enter. Good luck. Several people asked about the difference between the built-in administrator account and the administrator created on Vista setup. Unless you are a very experienced user (more than 5 years in serious technical support) and require very specific access privileges, then the default account should be fine–you will know if you need the built-in administrator when, no matter what you do, you cannot perform an operation–and you will know immediately that this is the problem. Yes, there is a difference, and no, you shouldn’t normally have to worry about it.
To answer other comments, above: User names are not case-sensitive for Windows logins, therefore you may type both Administrator and administrator. You can even type AdmINisTRatOR if you wish. In passwords, however, case does matter.
The built-in administrator has more privileges than the automatic administrator, regardless of UAC. In fact, it has a dangerous amount of privileges, and you should not use it–especially on a new OS with all-new security concerns–unless you know exactly why you need it. Greg asked about the “guest” account and Dan answered about the administrator account. The guest account is disabled by default, and the (disabled) administrator is not available for the password to be set. Further, to acquire pseudo-administrative privileges sufficient to enable the built-in administrator, you’d have to be know a pseudo-administrator’s password. Therefore, unless one gives the guest account administrator privileges, assuming the security policies hold appropriately, this is not an issue.
I am currently typing this message on a (fixed) Vista Business machine while configuring two new Vista Premium machines. I cannot speak for some OEM’s setting the built-in password to be the same as the first-created user, since I have not yet run into this, but all three of these machines failed to do so it was blank. I would be…disappointed if some OEM’s did this, by the way…because that would make these machines a little bit difficult to support.
UAC is indeed accessed through Control Panel. Start | Control Panel | User Accounts | User Accounts (yes, again) | Turn User Account Control on or off. You may, however, want to wait for the official release of SP1 in a few weeks; they’ve apparently addressed nuisance factors in UAC. People who don’t set logon passwords find that they cannot, for example, create schedule tasks, use file sharing appropriately, and/or access their computer from a network. These aren’t necessarily bad things, but it’s a little non-intuitive if you don’t realize what’s happening.
For the person who wants to login to the hidden administrator…was the article unclear? Follow the instructions carefully and you should be fine. If you are trying to “break in” to the built-in administrator from an account that does not have administrative privileges…why don’t you have access to an appropriate account? For those of you receiving “access denied” errors, you may not be starting the command prompt properly.
Many times these problems can be resolved by taking a closer look at the instructions and trying again. On previous versions of Windows, starting in Safe Mode was one of the easiest ways to reveal the built-in administrator, but on Vista, if the account is disabled you cannot use it to access safe mode. While this may lead some of you to conclude that “if my account ever gets corrupted I’d like that administrator around,” a better solution would be to create a second administrator and only login to it once (to setup the profile), then have the discipline to use it only when something bad happens to your main account.
You can then enable the built-in if you absolutely need it, but you’ll probably get all the privileges you need from your backup account. I believe the comment about setting the password at the prompt is accurate, and with that, I think that’s all of them. Good luck, folks. I know about this super Administrator but i need the normal administrator password to get to the super Administrator. I think it might be because the only account i can access is guest but is there any solution please help.
Hi I’ve got Windows Vista Business and the only account I have is an account which has guest privilege only – meaning I can’t use Run As Administrator, nor can I install anything … Everytime I try run as Administrator it wants a password – which I don’t have …. HELP???? You know how the WindowsXP Log-in window had a function where you could key in ctr+alt+del twice, and have a different login window come up where you could type in the administrator account? Does Vista have anything like this – so instead of going in and manually changing it all the time, could I access a hidden login window, type in the Administrator details and login?
Ugh, I’m having a problem. For some reason (I didnt even know it was possible) my only administrative account has been deleted. I had an additional account set up for my dad, but it has limited privelages.
This is currently the only account I can use. When ever I need to do something that requires a password from the administrator, it still pops up, but it dosn’t give me the option of typing in a password. Is their anyway I can recover my missing account, or activate the hidden administrator account without running the cmd as administrator. This total saga has turned out to be nothing but a total bloody joke for me. Here’s my story. I tried to setup Vista’s Admin Account using the following link: [mod removed] Anyhow all that part went well and after this I logged off and clicked on the Administrator icon in the start up screen.
Now on the start up screen I got an option to log into my previous user account in which works when I enter the password in, but when I applied the password I appled to the changes on how its layed out in the above link, Vista just totally refused it and would not allow me in, no matter how many times I put the password in. I even tried the reset password option using a USB Flash Drive and that did not help. I mean to simply put it, I’ve setup a Vista Admin account, followed the proper steps and made up a password but sadly when I try to login to Vista under Administrator it all fails.
Microsoft I am very dissapointed and if worse comes to worse and I got to call MS tech support i will not pay a cent to you lot, you made the error you fix it up, simple as that. !! IMPORTANT NOTE !!
Especially for Johan, and anyone else passing through…If you use that *other* link (or any other erroneous!! set of instructions out there) where you are told to type: C:\> net use administrator activate:yes *** YOU WILL SET THE ADMINISTRATOR’S PASSWORD TO “activate:yes” *** and I suspect that you will pay for support, because (and this is not meant to be harsh) this is your mistake–you followed bad instructions, and while that might be someone’s else’s mistake first, it is your responsibility to check the instructions, and it is your responsibility to read the comments. In the comments in Johan’s link. Arno Lips says: “step 6 is wrong”, corrects it improperly, leaves out what happens if you don’t correct it, and in the final case it was never fixed by the author–which should be a red flag. Many, many documents on the Internet also have this step, and it is going to cause you problems.
For people with bad spelling / careless fingers, anything you type there will be accepted, so if you mis-spelled that last parameter…yikes! Your options are now limited to fairly complex password reset tools (since you will have no reset disk for administrator), making the same typo again or–for most people in this situation–reinstall. If you do not care to learn about the problem, skip this paragraph, though I highly suggest you read it if you’re already playing in the command prompt and you didn’t realize the instructions were wrong. At a prompt, if you type “net user /?” you will be shown the help for the “net user” command.
Note that the parameter after the user name–if specified–is the password. In Windows, special command instructions almost always exhibit a forward slash (/). (Aside: Linux/Unix utilities.
