Thanks for posting in the Apple Support Communities HarleyW,
If you're unable to sign into iCloud for Windows, try accessing iCloud.com from a web browser to make sure you can sign in from there.
If you've forgotten your password, you can use the steps from this page to reset it: If you forgot your Apple ID password
If the issue persists, you can find additional information that may provide a solution, here: Resolve issues between iCloud for Windows or iTunes and third-party security software
We hope this helps!
