Intel Graphics Driver for Windows [15.40] - Files Not Signed With A Valid Certificate

Intel recently released new drivers on the below download page:
https://downloadcenter.intel.com/download/29804/Intel-Graphics-Driver-for-Windows-15-40-?product=975...

This was the original ZIP file from that download page:
win64_15.40.46.5144.zip
MD5: 8e7277d6071e303954380aca235fa2db

In this ZIP file, it wouldn't extract properly due to a problem with "igd11dxva32.dll". Also, a number of files in that ZIP file weren't signed with a valid code-signing certificate; they had been signed with an expired certificate.

Intel then released this new version of the ZIP file to fix the "igd11dxva32.dll" problem:
win64_15.40.46.5144.zip
MD5: b358258f4abae0d5711c7ae1892743fb

In this new ZIP file however, a number of .exe files still aren't signed with a valid code-signing certificate. They were signed on 10 August 2020 with a code-signing certificate that expired in 1 March 2020. These .exe files are therefore invalid and need to be signed with a certificate that is valid at the time of signing.

PowerShell code to check for .exe and .dll files without a valid code-signing certificate in the extracted ZIP file:

# Path
$Path = "$env:UserProfile\Desktop\win64_15.40.46.5144"

# Run
Get-ChildItem -Recurse -Force -File -Path $Path | 
Where-Object { ($_.Extension -eq ".exe") -or ($_.Extension -eq ".dll") } | 
Get-AuthenticodeSignature | 
Where-Object { ($_.Status -ne "Valid") } | 
Select-Object -Property * -ExpandProperty SignerCertificate | 
Format-List -Property Path, Status, StatusMessage, Subject, SerialNumber, NotBefore, NotAfter

 

Output from the above PowerShell script:
