Solve win7 forget to power on password

Windows 7 system forgetting to log in password is really a headache. Because you can't use Windows XP to access the administrator account, the auxiliary tools are relatively large. You can't get back to the xp era to delete the password, but use Windows7. Run the cmd command on the system account to force the account password to be modified! Take xp+Windows7 as an example (you can also enter pe without installing dual systems).
First step: Since cmd is in the system directory, file changes must first obtain file ownership. Open “D:\\windows\\system32” (assuming Windows 7 is installed on the D drive), right click on “arrator.exe” select “privacy”——advanced——owner, manage under current xp The account number is set to the owner (if there is no current account in the list, click “other accounts”, manually enter the current account name). Click the "OK" button to return to the Permission Settings window, click “Add”, add the current administrator account to the list, and set the account read permission for this file to "full control". The second step: the operation is the same as above, set the current account to "ldd;exe" privilege is completely controlled, then rename "narrator.exe" to "narrator1.exe", "ldd.exe", renamed to "ld" ;narrator.exe”. Step 3: (If you are logged in as the administrator account, you don't need this step) Restart Windows 7 and click the “Easy Access” button in the lower right corner of the login screen. In the window that opens, tick “"Start Narrator" ; At this time, the cmd window is started (it is opened by system, naturally has administrator rights~), enter the following command in cmd to open the administrator account, restart to use administrator: netuseradministrator/active:yes( Explanation: Force open the administrator account) netuseradministrator123456/add (interpretation: force the user administrator password to 123456) Step 4: Since the administrator account cannot be used, create a 呗, the same permissions as it will not work; restart Log in to Windows7, click the “Easy Access” button in the lower right corner of the login interface, and tick “Open Narrator” in the window that opens, start the cmd window, type: netuseradmin123/add, enter; netlocalgroupadministratorsadmin/add Step 5: Restart, enter the admin account A.
