Why I can't change windows 10 administrator password?

Ophcraack + Rufs for changing Windows 10 administrator password.

After reading the post, there are two software programs that can help you, Ophcraack and Rufus. When using these programs, you need to pay attention to the following points: you need to have a USB flash drive with a capacity of at least 2GB, and you need to download the Windows 10 ISO file in order to change Windows 10 admin login password.

Step 1: Insert an empty USB drive to open Rufus, select the USB drive, load the Ophcraack ISO file, click Start, and wait for the program to complete.

Step 2: Reboot the computer, press F2/Del to enter BIOS, set USB as the preferred boot device, save and exit. Then we can reset the password to do so, the computer boots from USB, enter the Ophcraack interface, automatically detect the Windows 10 account, select the administrator account 

Step 3: Tap Crack to view the password, or select Change to enter a new password, save the changes, and reboot the computer.

Step 4: Remove the USB, start Windows, log in with the new password and confirm administrator privileges.

Using Ophcraack to change Windows 10 local administrator account password, Rufus is responsible for writing Ophcraack's ISO file to USB flash drive as a boot disk, which is a good experience. Ophcraack recognizes and processes passwords quickly and intuitively, and can quickly restore account access rights. Overall, they work well together and effectively solve the problem of forgotten passwords.
