How to clear the Vista Password without tools (Dual System)

Today, my notebook used by a colleague in the company forgot the secret (dual system, forgot the Vista Password) and asked me to help clear the Vista Password. I have no system disk at hand, I searched a lot of methods on the Internet and finally clarified the Vista Password. The specific steps are as follows:

Because Vista adopts stricter logon authentication than XP, it is difficult for us to enter the system if we forget the logon password. However, Microsoft has a sticky key vulnerability on the logon interface, which can be used to access Vista. Start the command prompt, and then use the command prompt to enter vista to reset the account password. Here, the dual system assumes that the C disk is XP, and the D disk is vista.

Step 1: Open D: \ windows \ system32 after entering the XP system, right-click sethc.exe and select "properties" to open the Property setting window, click the "Security" tab, and then click "advanced ".

Step 2: switch to the "owner" tab in the Advanced properties security settings window, select the current XP Logon account in the owner list, click "Apply", and close all windows in sequence. Because the installation partition of vistais ntfsformat, we can only change the ownership of the sethc.exe file under Windows XP before performing the replacement operation. If the attribute window does not have the "Security" label. You need to open the resource manager, Click Tools> Folder Options, and select the check box before "use simple folder sharing (recommended)" in the window that opens.

Step 3: Set the full control permission of the role to "allow ". Then, start the command prompt and enter the following command to perform the replacement operation:
Rename D: \ windows \ system32 \ sethc.exe sethc1.exe(change the sticky key program to sethc1.exe ))
Copy D: \ windows \ system32 \ cmd.exe D: \ windows \ system32 \ sethc.exe(copy command prompt is sethc.exe)

Step 4: start the desktop. After successfully loading the file, we can see the Start Menu, which is the desktop started with the built-in system account (you can see it under the user icon of the Start Menu ).

Step 5: Enter "cmdmmc.exe" in the "cmdname prompt", start the console, click "File> Add/delete Management Unit", select "local users and groups" in the list of available management units, and click "add ". Return to the console window, expand "console section root> local user and group> User", select the account with the forgotten password in the right window, right-click and select "set password ", follow the prompts to change the password. After that, you can return to the logon window and use the new password to log on to Vista.
