Improvements
This non-security update includes quality improvements. When you install this KB:
This update addresses a known issue that affects the BCryptSignHash API. Because of this issue, the API returns “STATUS_INVALID_PARAMETER.” This occurs when callers use NULL padding input parameters for RSA signatures. This issue is more likely to occur when Customer-Managed Key (CMK) are in use, like on an Azure Synapse dedicated SQL pool.
If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.
