Computer Hope

I have Windows 10 Home.
I can't sign out of my Amazon account on my desktop computer.
I have tried the usual ie 'Accounts & Lists' but the drop down list will not show all the options.
Therefore, it doesn't display the 'sign out' option at the bottom of the list.
it's impossible to scroll down to the bottom of the list and my the automated Amazon 'contact us' does not assist!
Can anyone help me sign out?

If you dont care about passwords lost that were stored on the computers browser you can clear the browser of stored passwords and then it is forced to logout of amazon as the next time going to amazon it wont have the stored credentials to automatically logon. Then it will request for you to logon with user/password for all accounts.
