How to do if the Win7 system forgets the password

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, but you can use the Windows7 system account to run the cmd command to force the account password to be changed! Take xp+ Windows 7 is 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" and select "Permissions" - Advanced - Owner, set the current xp administrator account as the owner (if If there is no current account in the list, click "Other Account" and enter the current account name manually). Click "OK" to return to the permission setting window, click "Add", add the current administrator account to the list, and set the account read permission for the file to "Full Control". Step 2: Operate as above, set the current account to "cmd.exe" permissions for full control, then rename "narrator.exe" to "narrator1.exe" and "cmd.exe" to "narrator.exe" . Step 3: (If you log 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, check “Start Narrator”. The startup is the cmd window (it is opened by system, naturally has administrator privileges~), enter the following command in cmd to open the administrator account, restart to use administrator: netuseradministrator/active:yes (interpretation: forced open 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 privilege as it does not work; restart login Windows7, in Login interface Click the "Easy Access" button in the lower right corner, select "Start Narrator" in the window that opens, start the cmd window, enter: netuseradmin123/add Enter; netlocalgroupadministratorsadmin/add Enter; Step 5: Restart, enter The admin account is fine.
