Windows update makes sign-in password icon invisible — Microsoft says you can still click on empty space to enter your password

Microsoft's non-security preview update KB5064081 has caused the password icon on the lock screen to disappear, making it challenging to sign in. Users can still enter their password by clicking on the empty space where the icon should be. This issue mainly affects the Windows user interface and is part of a preview update, so only preview channel users are impacted. Microsoft is working on a resolution. Windows Updates can sometimes introduce new problems, as seen with recent issues affecting BitLocker, UAC prompts, and Windows Recovery Environment. Microsoft's Insider channels help catch bugs before wider release, but occasional issues still slip through.
