Unable to access my iTunes library on Windows 11

I have changed my password several times and still get the same response.

I'm not sure what you mean by that. If you cannot get into your account then you will not be able to change your password. However, if what you mean is that you tried different passwords at the sign in screen, I suspect that eventually iTunes will lock you out as it might suspect an attempt to break into your account by someone who is not authorised.

Try the following:

1. ensure that you are using the correct username (and if it's your email address, as is common), make sure you include all of it (i.e xxX@<email provider>.com), not simply the xxX part and that you are using the capitals and lower case correctly
2. ensure that the password you type in is also in the correct case; i.e. lower and upper case as you originally used
3. look carefully when you sign in for a message asking whether to trust this computer, or a message asking you to put in a code number that has been sent to your devices (iPod, iPhone etc.). I think there may be an option to have that code sent to your mobile phone, even if that phone is not an iPhone
4. if you really cannot remember the password, use the option on the sign in screen that says Forgot Your Password? (The wording may be slightly different to that)
5. See the following Apple article, which includes a link to Sign in to your Apple Account on the web or in your device settings – Apple Support (UK)
6. Here's a specific link to a sub page of that article, which offers suggestions for remembering the email address that you originally used, and even to use your phone number to sign in: If you have forgotten your Apple Account primary email address or phone number – Apple Support (UK)
