FIX KB5027215 Issue with Windows Hello Popup Message after signing

Let’s now find out what is the workaround for the issue with the OOBE screen Windows Hello Popup message after the installation of KB5027215 and restart of the Windows 10 PC.

ImKruptos is the user on Reddit who provided the workaround for this issue. This is the registry fix, and you need a registry value to avoid this popup happening again and again. The registry value is given below: BioConsentNoticeShownTime.

You will only see this OOBE style WHfB popup message prompt if you have biometric data stored in the PC. If you don’t want your end users to see this popup, you must create the following registry value.

  • Open regedit.exe
  • Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\WindowsHello\
  • Create a REG_BINARY value called BioConsentNoticeShownTime with a HEX value for the timestamp (more details below).

NOTE! The Hex value in that key is a timestamp when you click YES or NO on that OOBE popup screen. You have some tools to convert the current time hexa value. One of them is Unix Hex Timestamp Converter (epochconverter.com).

Another note from the user is that you can’t delete this registry key until Microsoft provides some sort of permanent solution otherwise, the If you delete that key after you have the latest patch and reboot, it will prompt you Windows Hello for Business OOBE style popup screen again.

Registry FIX Using SCCM or Intune or GPO

There are different methods to perform registry FIX using SCCM and Intune. The best way is to go with the remediation script in Intune. I will link different blog posts on this topic to give more details on the registry fix options. We need to deploy the above registry fix before installing the KB5027215.

KB5027215 Issue with Windows Hello Popup Message after signing – Table 1

I have not looked into creating an Intune remediation registry script for fixing this issue, but you can get several similar scripts from the community. The following is the Sample script that you can get from the internet!

# Define the timestamp in hexadecimal format - Change this accordingly if you like
$timestampHex = "64901e05"

# Define the registry path
$regPath = "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\WindowsHello"

# Create the registry key if it doesn't exist
if (!(Test-Path $regPath)) {
    New-Item -Path $regPath -Force | Out-Null
}

# Convert the hexadecimal timestamp to a byte array
$bytes = [System.Linq.Enumerable]::Range(0, $timestampHex.Length/2) | ForEach-Object { [byte]::Parse($timestampHex.Substring($_*2,2), [System.Globalization.NumberStyles]::HexNumber) }

# Set the BioConsentNoticeShownTime value with the hexadecimal byte array
Set-ItemProperty -Path $regPath -Name "BioConsentNoticeShownTime" -Value $bytes -Type Binary

  1. this not a fix but a hack

    technically, why is MS prompting, there must be a reason for it, so bypassing could cause issues later

    maybe just a legal thing, or might be migrating/securing some data
