Microsoft Windows 11

In Windows 11 Version 24H2 Build 26100.4770,
I noticed that under Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot the key "AvailableUpdates" has the wrong value of 0x400 instead of 0x40.

 

Should I change it to 0x40?

 

In the Event viewer I see many errors like:

The Secure Boot update failed to update a Secure Boot variable

Error Unknown HResult Error code: 0x800700c1

Origin: TPM-WMI, Event ID: 1796

 

The first error occurred on May 13th, 2025, after the installation of the KB5058411 update (OS Build 26100.4061) released on Windows Update at the same date
