Incorrect windows 7 password despite entering the correct login and password

Can someone please help me? after entering the correct password, I cannot start the laptop because it shows that the login or password is incorrect. I only have one account, and this is the administrator account. The password has been the same for three years, yesterday I worked on it normally and only in Excel, so I could not mix up anything. The language is set to programmer Polish, although I use French a lot, but even after rearranging the letters it doesn't work. I can't boot into safe mode either, and neither do I have any tile to reset my password. I will be grateful for help. I will write in advance that I do not mean breaking the password, but explaining what happened, I have no internet connection, so it is rather impossible for someone to break in.

Check that caps lock is not turned on

I'm not such a layman

Unfortunately, from what I know, the regulations prohibit describing the ways of breaking passwords but there are a lot of articles on this topic on the net, because you will probably have no choice but to break into your own computer.

Hello

The problem is really interesting. Question: has the computer been turned off or put to sleep after yesterday's use? The question is related to the fact that I have already encountered a case that after returning from sleep, despite entering the correct password, he was prompted for its incorrectness. Only restarting the computer helped. Caps Lock rejected - or maybe Num Lock? A lay question, but the steps used so far have not been described. Also, have you tried an on-screen keyboard or an external keyboard?

So yes, I did not turn off the laptop all day, only taking breaks it went to sleep, only in the evening I turned it off completely, after two hours, wanting to turn it on, I encountered this problem, turned it off again and left it overnight, from the morning the same. I checked caps lock and num lock, both keyboards also tried, I even downloaded a program to a USB stick, but it also did not work. It also cannot boot into safe mode. Could it be a virus?
Regards

if it was not breaking the rules, I would download Hiren's BootCD on another computer and run one of the password recovery programs from there.

I have an almost identical problem. The only differences are that the laptop worked for about 6 hours in a room with an open window (~ 15 degrees in the room) with only the screen turned off and a locked, logged in account - it was already the 3rd time and it was always when I left it for ~ 6h with an open through the window so my suspicions fell to temperature. Today I came home and I entered my room with these parameters and I see the user unlock window, I enter the correct password and nothing ... I enter it 10 times, still the same ... the way it turns out is clicking "Switch user" and then selecting my account and entering my password correctly - it works 100% but I am still not sure what causes such anomalies.

My laptop: Acer aspire 5741G
Intel i5 430m
Geforce GT 320M
Western Digital Scorpio Black WD2500BEKT

1x Corsair 2GB DDR3 1066Mhz


I dug up the topic because, as you can see, the problem still exists and there is no specific solution.

The end.

The problem does exist and it is not about breaking passwords but about a hardware or windows error ... the problem is that you know the password but windows tells you that it is wrong.

the same thing happened to me yesterday. computer normally turned off, turned on an hour later and unable to log into windows because it does not recognize the password.
I combined in 100 ways: language change, on-screen keyboard, capslock, safe mode, previous passwords, motherboard reset and loading older bios settings and nothing.
I was finally able to log in when I loaded fail-safe defaults in the BIOS and entered the password with the mouse from the on-screen keyboard without pressing any key on the physical. Interestingly, when I first tried to enter the password from the physical keyboard (it did not enter), the later attempt with the screen did not work. The second observation was that it was impossible to enter numeric characters from the physical keyboard, numlock did not help

Hello, it took some time to see if someone managed to fix the bug, because recently I got overdue or an update fixes it.
It's a bit of a pain considering having to reset your computer every time.

@Emergent Got all the updates from WU? Does this also apply to the laptop? After entering the login and password for windows, e.g. in a notebook, is everything correct?

It worked for me every time.
I hope I helped.
Until today (and years have passed) I do not know what caused this problem
