Summary

Microsoft has released a Microsoft security advisory about this issue for IT professionals. The security advisory contains additional security-related information. To learn more about the vulnerability, see
https://technet.microsoft.com/security/advisory/3174644

More Information

Included with this security update is a new default minimum RSA key size that the client will accept from the server. This new minimum is 1024 bits. This brings the versions of Windows that are listed in the "Applies To" section into parity with Windows 10 which already had this minimum RSA key size. Additionally, this key size minimum can now be increased or decreased through the system registry.

ImportantThis section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756How to back up and restore the registry in Windows You can add a DWORD value named ClientMinKeyBitLength which has a default value of 1024 (Decimal) to the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\PKCS To add this registry value, follow these steps:

  1. Click Start, click Run, type regedit in the Open box, and then click OK.

  2. Locate and then click the following subkey:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\

  3. On the Edit menu, point to New, and then click Key.

  4. Type PKCS for the name of the Key, and then press Enter. Select the PKCS key.

  5. On the Edit menu, point to New, and then click DWORD Value.

  6. Type ClientMinKeyBitLength for the name of the DWORD, and then press Enter.

  7. Right-click ClientMinKeyBitLength, and then click Modify.

  8. In the Value data box, type the new minimum key length (in bits), and then click OK.


    Note You do not have to restart the computer after you add or change this registry entry for the change to take effect. However, you do have to restart the computer if you delete the entry.

Important

  • All future security and non-security updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require update
