Windows 10: Required to type 'A1B2C3' before entering PIN

    Required to type 'A1B2C3' before entering PIN

    As of a week ago, I have been receiving the error message, "You've entered an incorrect PIN serveral times. To try again enter A1B2C3 below." The problem with that is that I have never entered my PIN incorrectly and am the only one that utilizes my desktop. I have ran malware/virus scans and have turned up zero discrepancies. Additionally, I reinstalled Windows 10 (and activated) a month ago after upgrading my motherboard, processor, and memory. So why is it asking me to enter in this letter/number combination EVERY time despite never having entered in my PIN incorrectly? This is rather annoying and essentially a two-step authentication factor, of sorts, that I did not ask for. Is anyone else experiencing this?

    This is a problem that pops up frequently on Windows phones which requires a phone reset. Unless someone comes by with a definitive suggestion, you might want to do a in-Place Repair Install/Upgrade which will take little over an hour and keep your files and programs.
