Those bootable toolkit solutions present problems of their own many times. By the time a user creates that bootable USB toolkit and sorts out any problems, they could have just clean installed Windows.
Some users reported BIOS updates causing them not to be able to reset their winlogon passwords on Dell PCs. The BIOS update was to fix the Meltdown\Spectre vulnerability.
Other security updates could also have caused it - whether on Dell or other OEM systems.
The inability to reset the winlogon password is not one specific issue on Windows; it is connected to multiple issues.

It's common sense... if you keep experiencing the issue of being locked out of your Windows account over-and-over and cannot reset your password every single time, then don't set a winlogon password. A Windows security feature that is unreliable to the point of it not working - or worse - locking you out of the system - is pointless to use it. And jumping through hoops to use it or fix it is even worse.
