Easy Fix

To automatically add the DefaultSecureProtocols registry subkey, click here.

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 is experiencing the problem, save the Easy Fix solution to a flash drive or CD, and then run it on the computer that has the problem.

Note In addition to the DefaultSecureProtocols registry subkey, Easy Fix will also add SecureProtocols to the following locations to help enable TLS 1.2 and TLS 1.2 for Internet Explorer.

The SecureProtocols registry entry with a value of 0xA80 to enable TLS 1.1 and TLS 1.2 will be added at the following paths:

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

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

Enable TLS 1.1 and TLS 1.2 at the SChannel Component Level on Windows 7

According to the TLS-SSL settings article, to enable and negotiate TLS 1.1 and TLS 1.2 on Windows 7, you must create a DisabledByDefault entry in the appropriate subkey (Client) and set it to 0. These subkeys are not created in the registry because these protocols are disabled by default.

Create the necessary subkeys for TLS 1.1 and TLS 1.2; create a DisabledByDefault DWORD value and set it to 0 at the following locations:

For TLS 1.1 registry location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client

DWORD name: DisabledByDefault

DWORD value: 0

For TLS 1.2 registry location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client

DWORD name: DisabledByDefault

DWORD value: 0
