Answer

Windows 7 supports TLS 1.1 and TLS 1.2. However, these protocol versions are not enabled on Windows 7 by default. On Windows 8 and higher, these protocols are enabled by default.

To enable TLS 1.1. and TLS 1.2 on Windows 7:


Import the following registry keys:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client]
"DisabledByDefault"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server]
"DisabledByDefault"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000

Alternatively, download TLS 1.x on Windows 7.zip and double-click to import the file: Enable TLS 1.x on Windows 7.reg.
