Why does my ICloud sign in page keep opening every few minutes no matter what I do?

Hello JimThurlow,

If you see repeated prompts to sign in to iCloud for Windows, your sign in attempt may not have been successful. Often times, this behavior can be caused by third-party security software. Resolve issues between iCloud for Windows or iTunes and third-party security software provides some steps to resolve this.

"Things to check first

Before you change your security software's setup: 

• Make sure that the date, time, and time zone are set correctly on your computer. Learn how to update these settings on a Mac or on a PC. 
• Log in to an administrative user account, not a guest account. Learn how to do this on a PC. 
• Update to the latest version of iCloud for Windows or update to the latest version of iTunes.
• Make sure that you have the latest software on your Mac or on your PC.
• Make sure that you set up Windows Hello. Learn how to set it up. 
• Make sure that you only have one type of security software installed. If you have more than one type of security software installed, you might experience performance issues."

Cheers!
