I've just upgraded to Win10, and I am trying to sign into my Microsoft Account in order to use Cortana, however I am caught in a loop and it won't accept my credentials.

The credentials are definitely right, verified by accessing the Microsoft account via . Also, if I type my credentials incorrectly when trying to sign in on my PC I am told the credentials are wrong - therefore I can be certain that the authentication process is taking place.

Steps are as follows:

• Start
• Type "Your Account"
• Enter
• Scroll down on the Setting window
• "Add a Microsoft account"
• Enter email and password (for Microsoft account)
• Sign in

Nothing happens. I am returned to the previous screen and not logged in.

The same is true when I place my cursor in the bottom left hand corner search bar. I am asked to sign in to be able to use Cortana, the dialogues about getting you to sign in just go round in a loop after I've entered my credentials.

I've found the answer from information posted by another user on the TechNet forum. Here is the link: Can't sign in to Microsoft Account.

I jumped straight to Step 4 in the reply marked as 'Solved', which was this:

Edit your registry

HKEY_USERS.DEFAULT\Software\Microsoft\IdentityCRL\StoredIdentities

Here, you will see the account that is giving you trouble. Delete (right click the email address and click Delete).

Settings, Accounts, add your Microsoft account back in.
