Visible Key Vulnerability in Vista

There are more and more users installing XP+Vista dual system, but there are always some Ma Daha who will forget the Vista account password. Since Vista uses a stricter login authentication than XP, if we forget the login password, it is very difficult for us to enter the system. However, Microsoft has a sticky key vulnerability in the login interface that can be used to access Vista. The sticky key vulnerability means that we press the Shif start sticky key in the login interface (sethc.exe in the system directory), so we can use the cmd.exe to replace sethc.exe in XP to start the command prompt, and then use the command. At the prompt, enter Vista to reset the account password. The dual system here assumes that the C drive is XP and the D drive is Vista. Step 1: After entering XP system, open d:\\Windows\\system32, right click on sethc.exe and select "Properties" to open the property setting window, click the "Security" tab, and then click "Advanced". Step 2: In the Advanced Properties Security Settings window, switch to the "Owners" tab, select the current XP login account in the owner list, then click "Apply" and close all windows in turn. Since the Vista installation partition is in NTFS format, we can only perform the replacement operation after changing the ownership of the sethc.exe file under XP. If the property window does not have a "safe" label. Need to open the Explorer, click "Tools → Folder Options", in the window that opens, remove the check box before "Use Simple Folder Sharing (Recommended)". Step 3: Open the properties window of sethc.exe again and switch to the "Security" tab, click "Add", add the current XP account to the "Group or User Name" list, and also the account to sethc.exe The Full Control permission is set to "Allow". Then start a command prompt and enter the following command to perform the replacement: Rename d:\\Windows\\system32\\sethc.exe sethc1.exe (rename 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: Restart the computer to log in to Vista, press Shif to start the sticky key in the Vista login interface, then the command is started. At the prompt interface, enter Explorer.exe to launch the desktop. After successfully loading the file, we can see the start menu, which is the desktop launched by the system's built-in SYSTEM account (can be seen under the start menu user icon).
