How to Turn On TLS 1.0 and 1.1 on Windows 11?

Activating TLS 1.0 and 1.1 in Windows 11 for Legacy System Compatibility

In the digital age, secure communication over a computer network is of paramount importance. The Transport Layer Security (TLS) protocol has long been a stalwart in this realm, ensuring that data transmission between two systems—such as your computer and a website’s server—is encrypted and secure. Over the years, various versions of TLS have been developed, with each iteration striving to enhance security and fix potential vulnerabilities. However, as with all technological advancements, the shift doesn’t happen overnight. While newer versions like TLS 1.3 offer heightened security features, many applications and systems still rely on older versions, like TLS 1.0 and 1.1, to operate efficiently. Windows 11, the latest operating system from Microsoft, is designed to align with the most up-to-date security standards, which might sometimes sideline these older protocols. This can pose challenges for users who depend on systems that require these older TLS versions. To bridge this gap, it’s essential to know how to enable these older versions if and when needed. In this comprehensive guide, we will delve deep into the steps and precautions necessary to turn on TLS 1.0 and 1.1 in Windows 11, ensuring you maintain compatibility without compromising on security. Whether you’re a seasoned IT professional or someone just trying to make an older application work, this guide aims to simplify the process for you.

How to Turn On TLS 1.0 and 1.1 on Windows 11?

To maintain compatibility with legacy systems and applications in Windows 11, activating TLS versions 1.0 and 1.1 might be necessary. Here’s a detailed step-by-step guide on how to do it:-

Step 1. First, launch Registry Editor.

Step 2. In the left sidebar of Registry Editor, navigate or browse to the following directory:-


Step 3. When you reach the Protocols folder, right-click on it and choose New > Key.

Step 4. Rename the new key to TLS 1.0.

Note: In case the TLS 1.0 key already exits under the Protocols folder, then skip this step.

Step 5. Again, right-click on the newly created TLS 1.0 folder and pick the New > Key option.

Step 6. Rename this new subkey Client.

Step 7. Now, right-click on the Client subkey and hover over “New,” and then pick “DWORD (32-bit) Value.”

Step 8. Give the name “Enabled” to this new REG_DWORD and press Enter.

Step 9. Then, double-click on the “Enabled” REG_DWORD and set its “Value data” to 1. Confirm by clicking “OK.”

Step 10. Now, navigate to the following path:-

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0

Step 11. Then, right-click on the TLS 1.0 and choose New > Key.

Step 12. Name this new subkey Server.

Step 13. After that, right-click on the Server subkey and choose “New” and then “DWORD (32-bit) Value.”

Step 14. Next, name this REG_DWORD “Enabled” and press Enter.

Step 15. Double-click on the “Enabled” REG_DWORD to open it.

Step 15. Change its “Value data” from 0 to 1, and finalize your change by clicking “OK.”

After completing these steps, TLS 1.0 and 1.1 will be successfully activated on your Windows 11 system.


Enabling older versions of the Transport Layer Security (TLS) protocol, such as TLS 1.0 and 1.1, can be a necessary measure for compatibility with legacy systems. While Windows 11 is designed with the latest security standards in mind, it still provides the flexibility to support these older protocols when required. The step-by-step guide provided above simplifies the process of activating these TLS versions, ensuring users can maintain essential functionality without compromising overall system security.
