`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols`

2. Identify the TLS version subkeys: Under the Protocols folder in the Registry Editor, you should see subkeys for various TLS versions. Look for the ones labeled `TLS 1.0` and `TLS 1.1`.

3. Modify the TLS version subkeys: To disable TLS 1.0 and TLS 1.1 and enable TLS 1.2, right-click on the `TLS 1.0` subkey, select Modify, and change the DWORD value to `0`. Repeat this step for the `TLS 1.1` subkey as well.

4. Create the TLS 1.2 subkey: If the `TLS 1.2` subkey doesn’t exist, you’ll need to create it. Right-click on the `Protocols` folder, select New, and choose Key. Name this new key `TLS 1.2`.

5. Create the Client subkey: Within the `TLS 1.2` key, create another key called `Client`.

6. Create the DWORDs for Client subkey: Right-click on the `Client` key, choose New, and select DWORD (32-bit) Value. Create the following DWORDs and set their values to `1`:
– `DisabledByDefault`
– `Enabled`

7. Restart the system: Once the above steps are completed, restart your Windows system for the changes to take effect.

8. Verify the TLS upgrade: After the restart, you can confirm the upgraded TLS version by either checking the Registry Editor again or using a third-party tool like OpenSSL to test the TLS connectivity with a website or server.

Please note that modifying the Windows Registry can have critical implications if not done properly. It is recommended to back up the registry or seek help from IT professionals to ensure a smooth and error-free process.
