    Hello @Peter_1985 ,

    Thank you for your update.

    So you find Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols, right?

    If so, then do as below:

    1-Right click Protocols->New->Key and rename the new Key TLS 1.0.

    2-Right click TLS 1.0->New->Key and rename the new Key Client.

    3.Right click Client->New->DWORD (32-bit) value.

    4-Rename "Name" as "Enabled" and modify Data as "1".

    5-Repeat step 3 and Rename "Name" as "DisabledByDefault" and modify Data as "0".

    6-Now TLS 1.0 is enabled.

    7-If you want to disable it, modify Data corresponding to "Enabled" as "0" and
    modify Data corresponding to "DisabledByDefault" as "1".

    Should you have any question or concern, please feel free to let us know.

    Best Regards,

    Thanks for update.
    Can you advise why I cannot find out "security" inside the following, within my current Win 10 Pro version?

    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

    Yes, there is no "security" under control below.

    Hi,
    I do not see TLS 1.0 within the following

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

    Can I know how TLS 1.0 is created within your machine?
