 How to enable TLS 1.2 on Windows Server 2008R2

 
  1. Start the registry editor by clicking on Start and Run. Type in "regedit" into the Run field.
 
  1. Browse to the following registry key:
  1. Right-click on the Protocols folder and select New and then Key from the drop-down menu. This will create a new folder.  Rename this folder to TLS 1.2.
  1. Right-click on the TLS 1.2 key and add two new keys underneath it. Rename the two new keys as Client and Server.
 
  1. Right-click on the Client key and select New and then DWORD (32-bit) Value from the drop-down list. Rename the DWORD to DisabledByDefault.
 
  1. Right-click the name DisabledByDefault and select Modify... from the drop-down menu. Ensure that the Value data field is set to 0 and the Base is Hexadecimal. Click on OK.
  1. Create another DWORD for the Client key as you did in Step 5. Rename this second DWORD to Enabled.
 
  1. Right-click the name Enabled and select Modify... from the drop-down menu. Ensure that the Value data field is set to 1 and the Base is Hexadecimal. Click on OK.
 
  1. Repeat steps 5 to 8 for the Server key (by creating two DWORDs, DisabledByDefault and Enabled, and their values underneath the Server key).
  1. Reboot the server.
 
The server should now support TLS 1.2.
