Microsoft pushed update KB5017380 to the Windows 10 Release Preview channel recently, and the system version was upgraded to Windows 10 Build 19044.2075. This update is mainly to fix various known issues with a testing nature. After testing, it will be gradually pushed as an optional update and finally merged into the B-type stable version update.
A noteworthy change in this update is that Microsoft began to disable the Windows 10 TLS 1.0/1.1 transport layer security protocol by default. These two old security protocols have been gradually deprecated because they are no longer secure.
Microsoft disables the TLS 1.0/1.1 protocol in all its own software, and Microsoft’s browsers, including Microsoft Edge and IE, also deprecate the protocol. Enterprises that still use these protocols may need to update them in time so as not to affect their normal use within the enterprise in the future.
Currently disabling the protocol does not affect any third-party software, but if the enterprise owns its own internal environment or develops integrated plug-ins for Office and the like, it must upgrade the server protocol, otherwise, you will not be able to use Office, Edge, IE and other loadings in the future.
Third-party browsers, such as Chrome, etc. have already disabled TLS 1.0/1.1 so there is nothing to say. If a business still decides to stick with TLS 1.0/1.1 then it can only use Internet Explorer, as you can manually re-enable TLS 1.0/1.1 or even SSL version 3.0 in Internet Options in Internet Explorer.
