DefaultSecureProtocols registry entry for TLS 1.1 and 1.2
Last Updated 4 months ago

How the DefaultSecureProtocols registry entry works:

When an application specifies WINHTTP_OPTION_SECURE_PROTOCOLS, the system will check for the DefaultSecureProtocols registry entry and if present override the default protocols specified by WINHTTP_OPTION_SECURE_PROTOCOLS with the protocols specified in the registry entry. If the registry entry is not present, WinHTTP will use the existing operating system defaults for Win WINHTTP_OPTION_SECURE_PROTOCOLS HTTP. These WinHTTP defaults follow the existing precedence rules and are overruled by SCHANNEL disabled protocols and protocols set per application by WinHttpSetOption.

Your administrator must manually add the entry. Or, you can install this: "Easy fix", from Microsoft to add the entry automatically.

To add manually:
The administrator wants to override the default values for WINHTTP_OPTION_SECURE_PROTOCOLS to specify TLS 1.2.

The DefaultSecureProtocols registry entry can be added in the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp


On x64-based computers, DefaultSecureProtocols must also be added to the Wow6432Node path:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp


The registry value is a DWORD bitmap and the value to be entered to enable TLS 1.2 by default is: 0x00000800

Easy fix info:
To add the DefaultSecureProtocols registry subkey automatically, click the Download button. In the File Download dialog box, click Run or Open, and then follow the steps in the easy fix wizard.

Note

This wizard may be in English only. However, the automatic fix also works for other language versions of Windows.

If you are not on the computer that has the problem, save the easy fix solution to a flash drive or a CD and then run it on the computer that has the problem.


Note

In addition to the DefaultSecureProtocols registry subkey, the Easy fix also adds the SecureProtocols at the following location to help enable TLS 1.1 and 1.2 for Internet Explorer.

The SecureProtocols registry entry that has value 0xA80 for enabling TLS 1.1 and 1.2 will be added in the following paths:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
