To manage TLS 1.2 permissions requires intimate knowledge of the registry. To Simplify this management See this Microsoft article for more information: https://docs.microsoft.com/en-us/windows-server/security/tls/tls-registry-settings To simplify the management of these settings, we use the program IIS Crypto from Nartec Software at Tricerat and it makes managing these security settings as easy as clicking a button. See their documentation here https://www.nartac.com/Products/IISCrypto for a complete description. We recommend using the Best Practices button. Make sure you understand the TLS/SSL requirements of other software you may use as weak protocols may be disabled by IIS Crypto. When making changes, a reboot is always necessary!
