SOLVED-Locked out of Dell Optiplex 780 due to "incorrect password" pin
Intermediate user here. Locked out of my Dell Optiplex 780 due to "incorrect Password" at PIN login screen. Already used another device to login to my Microsoft Account to change password-this worked. Cannot get past PIN login screen on the PC itself, and tapping F2,F4, F8, F10, F12 during startup process is useless to boot into Safe Mode. Only alternative boot screen that shows is the one asking which hard drive or optical drive to boot to when tapping f12. This is a clean, currently updated install of legit Windows 10 on a Dell Optiplex 780. The all caps button is not activated.
[Solution] The problem ended up being a old password was still in the memory to log on to microsoft; used it and got in. DID, however disable "PIN" login FOREVER! Turns out that you can choose to only use your Microsoft Password and opt out of PIN entirely.
