Microsoft Edge 157 reached the Stable channel on Nov. 5, 2026 as version 157.0.4341.42, according to Microsoft’s Stable channel release notes. The release adds sign-in with an Apple account, an upgraded Copilot new tab page, updated tab hover cards, and an opt-in launch setting for managed devices. It also finishes a sign-in change for Windows and starts the countdown for turning off browser-native XSLT. This guide lists what Microsoft Edge 157 changes, which policies and settings control each change, and what Microsoft’s notes leave unsaid.

Accelerated App Launch in Microsoft Edge 157
Accelerated App Launch makes Edge open faster on Windows when it is already running in the background. The notes set two requirements, shown in the table.
| Requirement | Detail |
|---|---|
| Windows version | Windows 11 25H2, 26H1, or 26H2 |
| Edge version | Edge 150 or later |
| Platform | Windows |
The notes do not say how a user turns the feature on or off, and they give no figure for how much faster the browser opens. Readers who need a newer Windows build can see the Jolt Journal’s Windows 11 Cloud Rebuild guide.
Sign-in changes for administrators in Microsoft Edge 157
Microsoft says Microsoft Edge 157 completes the move from direct WAM sign-in to OneAuth on Windows. WAM, the Windows account manager, is not being deprecated. Microsoft gives an administrator these steps to see which profiles still use WAM.
- Open
edge://signin-internalsin Edge. - Find Edge Auth Library Information, then Library.
- Look for profiles that still show WAM.
For early testing, Microsoft names a launch flag, msedge.exe --enable-features=msForceOneAuthWAM, and says all Edge processes, including background ones, must be closed first. Microsoft lists the NonMicrosoftAccountSignInEnabled policy for the Apple account option.
XSLT and other deprecations in Microsoft Edge 157
| Item | Date or version | Detail |

| XSLT admin override | Works until Edge 176 | Policy XSLTEnabled and the XSLT deprecation origin trial |
| XSLT tenant notice | Message Center MC1509789 | For tenant administrators |
| Copilot URL redirect | Edge 157 notes | Review allow and block lists and add *.cloud.microsoft; Message Center MC1462915 |

Web platform changes in Microsoft Edge 157
Microsoft’s separate web platform notes list changes for developers. The table picks the ones with the clearest descriptions.
| Feature | What it does |
|---|---|
CSS corner shorthand |
Sets border-radius and corner-shape in one declaration, such as corner: 20px squircle; |
text-overflow custom string |
Shows a chosen string when content is clipped, such as " (more)" |
text-decoration-inset |
Controls how far underlines and similar decorations extend past the text edges |
displaymode="icon-only" |
Renders the <camera>, <microphone>, and <geolocation> elements as compact buttons without text |
| HTML-in-canvas | Draws HTML elements into a canvas, with drawElementImage() for 2D contexts |
| HTML insertion methods | New positional and streaming methods, such as appendHTML() and streamHTML(), with Unsafe variants |
How to check a PC for Microsoft Edge 157
These steps are the Jolt Journal’s own suggestions, and Microsoft’s notes do not list them.
- Open
edge://settings/helpto see the installed version and trigger an update check. - Compare the version with 157.0.4341.42, the build Microsoft names for the Nov. 5 release.
- Check the Windows version before expecting Accelerated App Launch, since it needs Windows 11 25H2, 26H1, or 26H2.
- On a work PC, ask the administrator whether the
LaunchEdgeOnWindowsStartupEnabledandNonMicrosoftAccountSignInEnabledpolicies are set.
Browser updates are a security habit as well as a feature question, and the Jolt Journal’s guide to updating Chrome covers the same routine for the other major browser.
What Microsoft’s notes leave open
The notes for Microsoft Edge 157 do not give a date for when every user will see the autolaunch opt-in, because Microsoft calls it a controlled rollout. They do not say which markets get Apple account sign-in, and they do not describe how the Copilot new tab page can be turned off. The notes also do not say whether Accelerated App Launch applies on devices where Edge is not set to run in the background.
Who needs to act on Microsoft Edge 157
This table is the Jolt Journal’s own summary of the notes by reader type, and Microsoft does not publish it in this form.
| Reader | Items in Microsoft Edge 157 to look at |
|---|---|
| Home user on Windows 11 | Apple account sign-in, the hover cards, and Accelerated App Launch on 25H2, 26H1, or 26H2 |
| Web developer | The XSLT change in Edge 159 and the new CSS and HTML features |
| IT administrator | The WAM check, the Copilot allow-list entry, the new policies, and Message Center items MC1509789 and MC1462915 |
Editor’s take
Microsoft Edge 157 is a release where the administrator’s checklist is longer than the user’s. The visible changes are small, with hover cards, a new Copilot icon, and an Apple sign-in option, while the policy and deprecation items affect managed fleets. Teams that rely on XSLT in Microsoft Edge 157 and later have until Edge 159 for the default change and until Edge 176 for the override, which leaves time to plan a migration.
This is general information based on Microsoft’s release notes. Features roll out gradually, and Microsoft’s own pages have the final word.
