HI ebenaryeh:
Hope you are having a good day! It will give me great pleasure to assist you!
I understand you forgot your password, and were using the fingerprint option. Now that you have done a system restore you are no longer able to enter password either way. I am sending you a link to a Windows document on resetting password.click here. If this did not work, you may want to consider a third party software resetting tool. There are many you can get for free. There are also videos on You Tube that you may wish to view on this subject. If all else fails, you could look into some data recovery software to retrieve your important information. You could also try restoring to a date prior to the one you selected before. Please let me know if one the options resolved it for you.
