Windows 10: Windows says my password is wrong

I normally sign into windows 10 on my computer using a local account. I have been using the same password for years so I know that the password is correct. Last night I wanted to download and install a desktop theme and my computer asked me to login to my Microsoft live account in order to do this. I installed the theme and thought nothing more about it. This theme was from the Microsoft website, not some strange one. Anyway, today I tried to log on to my computer using my usual password and got the message that my password was incorrect. So then I thought maybe it wanted my Microsoft password so I tried that, it still says my password is incorrect. I have tried old passwords thinking maybe somehow my computer had reverted to an old one. Nothing works. I cannot go to command prompt or any of the other things I have read about to fix this because everything I try to do asks for my password first. There are no options on my computer for logging on to it another way, no pictures, no pins, etc. I am able to log into my Microsoft account and see my device there. I can also locate it from my account. I have no idea what else to do to get back on to my computer. I even tried clicking the forgotten password option after entering the wrong password and it says I have to have a usb device, which I have read would have had to have been set up before I got locked out of my computer. I now feel like Microsoft is holding my computer hostage. Any help here would be appreciated.

Wrong Password

The "Old Password" is the password to your local account. It is about to change your local account to a Microsoft Account. If you don't mind this, then enter your local account password. If you think this is overly intrusive of Microsoft, don't do it and let Cortana die.
