After that Windows update checking the programs, on my uptodate VPro 19 Build 643 I got this pop-up:

Curious I followed that so called update.
After a very slow download the program started the "update" .
It wanted to install Vegas 20, which was already installed with build 214.
It wanted first to deïnstall the present 20 and after that install the new update.
That I cancelled of course.
The only problem that stays is that every time I start V19 the whole proces starts again.
How can I get to stop this nonsense?
