Smartcard authentication issues might occur with the October 2025 Windows update

Smart card authentication and other certificate operations might intentionally fail after installing Windows Updates released on or after October 14, 2025 (KB5066793) that contain protections for the security vulnerability, CVE-2024-30098. As part of this cryptography improvement, RSA-based smart card certificates are required to use KSP (Key Storage Provider) instead of CSP (Cryptographic Service Provider).

Common symptoms for certificates that use CSP include:

• ​Smart cards not being recognized as CSP providers (Cryptographic Service Provider) in 32-bit applications
• ​Inability to sign documents
• ​Failures in applications relying on certificate-based authentication
• ​Users might observe error messages such as "invalid provider type specified" and "CryptAcquireCertificatePrivateKey error."

You can detect if your smart card will be affected by this security enforcement if, prior to installing the October 2025 Windows security update (KB5066793), the System log contains Smart Card Service or Microsoft-Windows-Smartcard-Server Event ID: 624 with the message text: "Audit: This system is using CAPI for RSA cryptography operations. Please refer to the following link for more detail: https://go.microsoft.com/fwlink/?linkid=2300823."

Resolution:

For a permanent resolution, developers should update their authenticating app to perform Key Storage Retrieval using Key Storage API documented at Key Storage and Retrieval. Developers should complete this change before Windows updates released in April 2026, at which time the DisableCapiOverrideForRSA workaround listed below is planned to be removed.

Workaround:

If you encounter this issue, you can temporarily resolve it by setting the DisableCapiOverrideForRSA registry key value to 0. This is documented in CVE-2024-30098. Detailed steps to modify the registry key are listed below. Note: This option will be removed in Windows updates, planned for release in April 2026.

Steps to Modify the Registry

⚠️ Important: Editing the registry incorrectly can cause system issues. Always back up the registry before making changes.

1. Open Registry Editor.

• ​Press Win + R, type regedit, and press Enter.
• ​If prompted by User Account Control, click Yes.

2. Navigate to the subkey.

• ​Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais

3. Edit the key and set the value.

• ​Inside Calais, check if key DisableCapiOverrideForRSA exists
• ​Double-click DisableCapiOverrideForRSA.
• ​In Value date, enter: 0

Note: The DisableCapiOverrideForRSA registry setting is NOT added by the default OS install or the installation of Windows Updates and must be manually added on each device.

4. Close and restart.

• ​Close Registry Editor.
• ​Restart the computer for changes to take effect.

Affected platforms:

• ​Client: Windows 11, version 25H2; Windows 11, version 24H2; Windows 11, version 23H2; Windows 11, version 22H2; Windows 10, version 22H2
• ​Server: Windows Server 2025; Windows Server 23H2; Windows Server 2022; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2

Parental consent may not show for some browser versions with web filtering on

Certain laws require Microsoft to protect children from harmful and illegal content on the internet. Microsoft is committed to creating tools for parents and guardians to help them in guiding their children’s digital experiences and protect them from harmful and illegal online content.

One of the available tools is web filtering, which lets a parent or guardian filter websites. Currently, Microsoft Edge is the only supported browser that provides this functionality within Microsoft Family Safety, allowing Edge to be used by default on the child’s device after web filtering is enabled. Once web filtering is enabled, a parent or guardian needs to approve other unsupported browsers (any browser other than Edge) before they can be used. This helps parents understand that different settings apply to other browsers when it comes to blocking inappropriate websites and filtering search results for their children.

The blocking behavior continues to work for unsupported browsers, however, when unsupported browsers update to a new version, the latest version of the browser cannot be blocked until we add it to the block list. Microsoft is currently adding the latest versions of unsupported browsers, to the block list. As a result, some browsers may temporarily appear unblocked during this update process. We're actively working to ensure all latest versions of browsers are blocked, reinforcing our commitment to parents and guardians.

As Microsoft continues to update the block list, we’ve received reports of a new issue affecting Google Chrome and some browsers. When children try to open these browsers, they shut down unexpectedly. However, the standard workflow is to prompt a parental approval message stating, “You’ll need to ask to use this app”. Once the approval is consented, the browser operates as intended. This issue is only observed when the Activity reporting feature is turned off.

Workaround: The browser shutdown issue can be temporarily mitigated by turning on Activity reporting under Windows settings in Family Safety. Parents will then be able to receive approval requests as expected.

Resolution:

• ​Temporary access to unsupported browsers: As of June 25, 2025, Microsoft included the latest versions of unsupported browsers into the Family Safety’s feature, and they are now blocked as intended. However, new versions of unsupported browsers released after this date might temporarily appear unblocked. This temporary gap will be resolved in the future, and this documentation will be updated to inform you when the full resolution is available.
• ​Missing parental consent prompt: Fixed in the July non-security preview update (KB5062663), released July 22, 2025. The fix is gradually rolling out and will be automatically enabled on devices with KB5062663 installed or later updates.

Affected platforms:

• ​Client: Windows 11, version 24H2; Windows 11, version 23H2; Windows 11, version 22H2; Windows 10, version 22H2
• ​Server: None
