Update: vivetool has now worked with the latest version, contrary to what I mentioned earlier that it didnt. All these msedgewebview2 processes are gone. I'm running win x-lite 25h2 with startallback as a smart menu . When I had it running, the processes were not present which was what I wanted. However, it was causing my screen to go black upon refreshing the desktop which is the reason I wanted to go back to stock smart menu.
vivetool.exe /disable /id:37926450
Wonder If it could have done through Group Policy or anything without using a tool.
