If you see an error message when you try to sign up for a Microsoft account, try the following:
If the error message has the error code 450 or starts with the letters LEFKPK, there's probably a temporary problem with the Microsoft account sign-up service. Wait 24 hours, and then try to create an account again. If you still can't create an account after 24 hours and the error message you receive includes 675b, keep waiting, and then try again.
If the error message you receive includes 0x800482d4 or starts with LEFKPK, contact Microsoft support to get more help.
If you're having other problems with your Microsoft account, you can try running the Microsoft Accounts troubleshooter. It's an automated tool that can find and automatically fix some problems. It's only available in English, but will work in all languages.
