Why does my login keep saying incorrect password
I have recently had a problem logging into my laptop at startup and when I close the lid. When it says enter password, I put it in and then it says "Incorrect Password". I try again and again and again and it keeps saying incorrect. I restart my computer, shut it down etc and try again and it still says incorrect password (even though I am typing it correctly). Restart, Shut Down, Try again and it just keeps saying incorrect. Then all of a sudden when I type it in it works.
So frustrating but wondering if someone could help explain why this is happening. Note that this is at the login screen when the computer is first powered up, and I am typing the correct password everytime I try. I am using Windows 10 Pro
Is this a good question?
