"微软网页浏览器" can be translated as "Microsoft web browser" in English.
If you want to be more specific and refer to a particular version or product name released by Microsoft, such as Internet Explorer or Microsoft Edge, you could say:
Internet Explorer (for the older browser)
Microsoft Edge (for the current, more modern browser)
But "Microsoft web browser" is a general and accurate way to refer to any web browser developed by Microsoft.
