Windows 10: Windows 10 Installation asks for but rejects password

My laptop received news that I could download and install Windows Pro 10. Everything went sweet until it ask me for my password to continue. I put the 4 digit password that I have been using since I bought this laptop last May. It would not accept it. I tried using my Microsoft password. It would not accept that. I've tried using my Acronis boot disk to put Windows 8.1 back on the laptop, but it will not do that. It keeps going back to the password page. It is stuck there until I can give it the correct one, but I've tried the only passwords I knew for it. I've tried rebooting using F2, F8, and Delete to get into the BIOS to make it recognize the CD/DVD drawer, but no luck. I'm at a loss on what to do. Before I pull my hair out, does anyone have a solution for me???

Sign in security-pin and password

I currently have no password or pin required to sign into windows 10. I would like to establish a pin. Trouble is windows asks for my password in order to setup the pin. If I leave the password space blank it rejects it as the wrong password, if I put
in my microsoft account password it rejects it also. How do I get past the password required step? Thanks.

 

my computer is Inspiron 22 PC with Windows 10. It suddenly locked me out. I reset the password but that didn't help. what can I do next?

My new computer is a desktop PC with Windows 10. After working fine it suddenly showed a picture and asked for a password which it rejected. I reset the password and that was rejected. I tried the Microsoft help but it was useless. I'm an old lady who
is not computer-savvy but needs it for work. I'm using my daughter's laptop to seek help.

 

I had that issue. Do you see, at the bottom of the page, "Not 'Your Name'?"? I clicked on my "Not ?" and it took me right into the other Admin's account. Of course, that assumes you have more than one account on the pc.

 

Yes, I discovered that. My what a relief. Thanks for your reply. I appreciate it.
