Hello,
Thank you for posting in Q&A forum.
The term "Windows sign-in" generally refers to the process of entering credentials (username and password, PIN, or biometric data) to access a Windows account on a device. This may happen in the following situations:
- When starting or restarting the device: This is the most common situation for Windows login. Once your device boots up, you'll need to enter your credentials to access your account.
- When unlocking your device: If your account is locked (either manually by you or automatically due to inactivity), you will need to log in again to unlock it.
- When switching users: If you switch from one account to another on the same device, this is also considered a login event.
So what you said about unlocking the locked login box and restarting the device are considered Windows login events.
For Windows sign-in options, please refer to the following link: Windows sign-in options and account protection - Microsoft Support
I hope the information above is helpful.
Best Regards,
