I'm searching Microsoft Netmeeting for Windows 10, but I think it's discontinued. Do Microsoft have alternative for Microsoft Netmeeting on Windows 10? If not, what is the best third party...

Okay, I have updated my Windows 10 from version 1803 to version 1903 and none of my data and file is missing or erased.

Do you want to say that my data and file will be erased after update?

I'm offered the feature update to Windows 10 Version 1903 from Windows Update. Here the screenshot (When i'm installing the updates).
