Microsoft has already issued a patch for this specific issue, but now it has also addressed another significant problem impacting multiple versions of Windows.<\/p>\n<p>According to Microsoft\u2019s <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/learn.microsoft.com\/en-us\/windows\/release-health\/status-windows-server-2022#3697msgdesc\">Windows Release Health dashboard<\/a>, a fix is available for a smart card authentication issue that arose following the installation of October 2025&#8217;s Patch Tuesday updates. Post-update, numerous users encountered errors linked to smart card recognition and certificate-related functions. Applications relying on certificate-based authentication began failing, displaying Event ID 624 in the system event log along with messages citing &quot;invalid provider type specified&quot; and &quot;CryptAcquireCertificatePrivateKey error&quot;.<\/p>\n<p>Microsoft has acknowledged that this issue stems from a recent Windows update that necessitates the use of the Key Storage Provider (KSP) rather than the Cryptographic Service Provider (CSP) for RSA-based smart card certificates. This change was made to bolster security.<\/p>\n<p>However, the resolution will not be delivered via a standard Windows Update. It requires manual modification of a Windows Registry value, which introduces a risk of system instability if done incorrectly. If you feel confident about proceeding, here are the steps you need to follow:<\/p>\n<ol>\n<li><strong>Open Registry Editor<\/strong>: Press Win + R, type <code>regedit<\/code>, and hit Enter. Confirm any User Account Control prompts.<\/li>\n<li><strong>Navigate to the subkey<\/strong>: Path to follow is <code>HKEY_LOCAL_MACHINESOFTWAREMicrosoftCryptographyCalais<\/code>.<\/li>\n<li><strong>Edit the key and set the value<\/strong>: Within Calais, check if the key <code>DisableCapiOverrideForRSA<\/code> exists. Double-click it and set the value data to: <code>0<\/code>.<\/li>\n<li><strong>Close and restart<\/strong>: Exit Registry Editor and restart your computer for the changes to take effect.<\/li>\n<\/ol>\n<p>This bug has affected Windows 11 (versions 25H2, 24H2, 23H2, 22H2), Windows 10 (version 22H2), and various Windows Server versions including 2025, 23H2, 2022, 2019, 2016, and 2012 R2.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In recent days, reports have surfaced regarding a critical bug in the Windows Recovery Environment (WinRE) that renders USB devices non-functional.
