That's why most third-party Windows password reset program doesn't work on current laptops/tablets and that's why you need to use this Windows Password Refixer to reset the password on your Lenovo ThinkPad tablet.

2. As you can see, the Lenovo ThinkPad tablet password reset process requires another computer and a USB device. If you really have no either one of them or you just don't want to use any third-party program like Windows Password Refixer, then you have to factory reset your Lenovo ThinkPad tablet to wipe forgotten password if you don't mind spending much more time and losing data on your Lenovo ThinkPad Windows 8/10 tablet.
