“Remove user email from the login screen, it's private info”
Many believe that Windows 10 has a privacy issue because a number of built-in services are being used to collect and transmit your data to Microsoft, but this isn't the only way that the new operating system might actually put your information at risk.
For example, the login screen of your Windows 10 PC shows not only your profile picture and username but also the email address, which for some users represents a violation of privacy.
So as a result, posts in the Windows 10 feedback app call for the company to update the operating system and remove the email address from the login screen because, otherwise, anyone can see it and use it for all kinds of malicious purposes.
“Stop showing my email address on the lock screen, please,” one suggestion reads. “Please remove user email from the login screen. It's private info,” another one adds.
