Thank you for asking this question on the **Microsoft Q&A Platform. **
I understand that you require that you automatically log in to your Microsoft 365 Account with your Windows credentials, right?
Well, I think you need Azure Active Directory Seamless Single Sign-On:
Azure Active Directory Seamless Single Sign-On (Azure AD Seamless SSO) automatically signs users in when they are on their corporate devices connected to your corporate network.
Hope this helps,
