Was the lockout the result of a malware of phishing Microsoft support scam? For a syskey password there is another software but I will have to go back in my records to find. If the syskey password is long I don't think it will work. You could try deleting the hibernation file using a Windows 10 install disk and the command prompt. Then do a ntfsfix.
Before I did that though I would mount the drive read only and copy the personal data.
The offline registry editor may work but I am not sure it would work for Windows 10
As you can see, with Offline NT Password & Registry Editor you’re able to reset forgotten syskey startup password in minutes. However, the utility can just as easily destroy a Windows system’s data. For that reason, the tool should only be used as a last resort.
