Hi,
There are several possible reasons why the Windows security keeps on popping up. This may include the settings on your computer or a corruption within the user profile. In order for us to efficiently assist you, we just have a few questions for you:
- Were there any changes made to your computers prior to the issue?
- Are your computers connected to a secured network?
- When does the pop up usually appear? Is it when booting up or when launching an application?
- Have you tried using the "Use a method not listed here" option?
Regards.
