On start of PC, Multiple MS Edge windows are getting started. Does anyone have a fix for this issue?

Check your Windows Startup programs and see if there is any suspicious or unknown program?

In Windows 10, open Task Manager and open startup.

I have seen some malware where they put the program into infinite loop and such issue happens.

Normally Anti-Malware would be able to detect it, but you need to check startup first and find it.

It might be a program where trying to connect to website (not opening browser) and if Microsoft Edge is your default browser, it will open it up.

3venk Thank you for reporting that to us, and welcome to the MSFT Edge Insider's community! Here are a couple of initial questions for you:

1. What version/channel are you currently using?
2. Do you see the same behavior in any of the https://www.microsoftedgeinsider.com/en-us/download?
3. And most importantly, if you haven't done so yet, can you please submit detailed feedback and diagnostics through the browser? (Shift+Alt+I) There is a place for you to attach that screenshot, too.
