I'm not advocating any brute force cracking, because it's a risky thing to use before you know anything about cracking tools. https://www.windows10passwordreset.com/ https://pogostick.net/~pnh/ntpasswd/ but I've used them and they don't interfere with other devices.

An upgrade was tried last year, but failed.

The first time I solved this problem, I reinstalled new OS, and that was a painful lesson. The second time I solved this problem, I used the boot disk.
