To check the TLS version in Windows Server Registry, open the Registry Editor (regedit.exe) and navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL
Under this key, look for the value “Protocols.” This value contains all the secure protocols that are enabled for use on the computer. Look for the keys SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1, and TLS 1.2. If any of these keys are present and have the DWORD value Enabled set to 1, then that version of the secure protocol is available.
1. Open the Registry Editor.
2. Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
3. Look for the registry key for the protocol you want to check the TLS version for. For example, the registry key for TLS 1.2 is TLS 1.2.
4. Open the registry key and look for the Enabled DWORD value. If it is set to 1, then the TLS version is enabled.
5. To check the version of TLS, look for the DWORD value named ClientMinVersion. The value corresponds to the version of TLS. For example, if the value is 0x00000300, then the TLS version is TLS 1.2.
