When letters or punctuation consistently appear in different positions from the key labels, Windows may be using a different keyboard layout. This is especially noticeable after adding a language, using an imported laptop or switching between keyboards.

Test a few harmless characters in a blank text document. Note which keys produce the wrong symbols and whether the behaviour is consistent. Do not test by typing your password into a visible document. If the issue followed a liquid spill or physical damage, stop treating it as a settings exercise and protect the device first.

Check the active input layout

Use the input-language indicator on the taskbar to inspect the selected layout. Choose the layout that matches the keyboard you are using and repeat the same test. Windows can have more than one layout for a language, so the language name alone may not identify the intended key arrangement.

To review installed choices, open Settings, Time & language, Language & region and inspect the relevant language's options. Add or remove keyboard layouts deliberately. Removing an input method someone else relies on can create a new problem on a shared PC.

The Windows display language controls interface text; the keyboard layout controls input. Changing one is not a reliable substitute for choosing the other. You do not need to redesign the entire language setup just to correct a few misplaced symbols.

Check the sign-in screen too

Microsoft notes that a display-language change can also affect the keyboard layout at sign-in. If a known password is rejected after such a change, inspect the sign-in screen's language indicator and choose the correct layout before repeatedly retrying.

After correcting it, test letters, numbers and the punctuation you commonly use, then reopen the affected application. If individual keys still fail regardless of layout, record that separate pattern. A software layout explains consistent remapping; it does not account for every intermittent or physically damaged key.
