Windows 7 forgot to log in password solution

            Because you can't use the administrator account to enter Windows7, the auxiliary tools are relatively large, and you can't return the pe key to delete the password in the xp era. However, you can use the Windows7 system account to run the cmd command to force the account password to be modified! Take xp+Windows7 as an example. (You can also enter pe without installing a dual system). The first step: Since cmd is in the system directory, file changes first need to obtain file ownership. Open “C:/windows /system32” (assuming Windows 7 is installed on the C drive.), right click on “arrator.exe” select “permission”——advanced——owner, under current xp The administrator account 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: Forcibly open the administrator account) netuseradministrator123456//add (interpretation: forcibly change 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. Re-login 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; netlocalgroupadministrators Admin //add Enter; Step 5: Restart, enter the admin account on it.
