Should you update to Microsoft Edge 149.0.4022.52?
No: install Microsoft Edge 156.0.4314.58 instead. Microsoft Edge 149.0.4022.52 is a security update Microsoft released on 4 Jun 2026 for Mac and Windows. It fixes 360 security flaws.[1] None of them is known to be used in attacks.
It has since been replaced by Microsoft Edge 149.0.4022.53, released 8 Jun 2026, which includes all of its fixes. If you’re on an older version, install that instead.
Should you update?
No: install Microsoft Edge 156.0.4314.58 instead. Microsoft Edge 156.0.4314.58 came out on 30 Oct 2026 and includes every fix in Microsoft Edge 149.0.4022.52, so there’s no reason to stop at this one. Software Update offers the newest version your device can run.
Is Microsoft Edge 149.0.4022.52 still safe?
Not any more. The 44 updates since, up to Microsoft Edge 156.0.4314.58, fix 2,626 security flaws that Microsoft Edge 149.0.4022.52 doesn’t, and each became public the day its fix shipped. Installing it is safe: get it only from Edge’s own About page (Edge updates itself; there’s nothing to download from a website), never from a link in an email, text or pop-up.
