Windows 10: Windows 11 Update KB5015882 fails with error code 0x8000ffff

Second time in a row now with a Windows 11 Update and exactly the same error code of 0x8000ffff. Had the same error code with the previous update.However, this time the issue is affecting both my PCs and both with the same error code.Never had a problem before.Absolutely fed up with this nonsense which has wasted most of the day trying to get the updates to install on my two systems, without success.How do I fix it?

Windows 7 SP1 Update failes with error code 0x8000ffff

Hello,

Trying to update Windows 7 with service pack 1 x64 (KB976932) on my notebook fails with error code 0x8000ffff.

Digging into %windir%\Logs\CBS\CBS.log shows the error in detail:

Error CBS SPI: (SPCompat::GetBIOSInformation:322)Model property of Win32_ComputerSystem class is not a string hr=0x8000ffff

Error CBS SPI: (SPCompat::CheckBIOS:374)Failed to get BIOS information hr=0x8000ffff

Error CBS SPI: (SPCompat:riverScan:43)Failed checking BIOS hr=0x8000ffff

Error CBS SPI: (CSPInstall::CompatibilityApplicabilityScan:1415)Failed to perform driver scan hr=0x8000ffff

Info CBS SPI: Ending Compatibility\Applicability scan

Error CBS SPI: (PerformSPInstallation:833)Failed to install SP using UI hr=0x8000ffff

Error CBS SPI: (wmain:1105)Failed to perform SP installation hr=0x8000ffff

Looking into Win32_ComputerSystem (Win32_ComputerSystem class - Win32 apps | Microsoft Docs) shows how the property Model is retrieved. I checked all the SMBIOS values with dmidecode. Here is an extract for type 1:

Handle 0x0001, DMI type 1, 27 bytes

System Information

Manufacturer: Not Specified

Product Name: Not Specified

Version: 1.06A

Serial Number: Not Specified

UUID: Not Settable

Wake-up Type: Power Switch

SKU Number: N/A

Family: A30

The needed values are not provided. I do not see a reason to abort the setup because of this. How can I force the setup to ignore these missing fields?

Best regards.
