The problem

Your default apps should stay where you put them

You picked Chrome, VLC and your favourite PDF reader. Then an update arrived, a notification said "An app default was reset", and everything opened in Edge again.

"An app default was reset"

Windows quietly ignores some choices and puts its own app back, usually after an update, with nothing but a brief notification.

One type at a time

Settings makes you change .mp4, .mkv, .avi and a dozen more one by one, then hunt through a list of hundreds.

Edge, whatever you choose

Links from Windows Search, Widgets and News open in Edge even when another browser is your default.

Defaults pointing nowhere

Uninstall an app and its file types can be left pointing at nothing, so Windows asks every single time.

Fixes that fight Windows

Quick fixes from forums switch off Windows' protection or hook into Edge, and can stop working after the next update.

No undo, no record

Change the wrong thing and there is no list of what you set before, and no way back except doing it all again.

Vow Default App Fixer fixes all of it.

How it works

Pick. Confirm. Keep.

Every file and link type on one screen, set the way Windows itself does it, so the choice sticks.

  1. 01

    See every default at once

    14 kinds of files and links on one screen, each with the app that opens it, plus a Needs a look list of choices Windows is about to reset.

    Click a card, pick an app

    Installed apps that open that kind are listed with the dedicated ones first. Every type the app handles is set at once, with a backup taken first.

    Confirm where Windows insists

    Browsers, PDFs and Office files can only be set in Windows' own window. Vow opens it for you and ticks each type off once Windows has it.

Set the app for every kind of file and link, and make the choice stick, in a few minutes.

Step 1: get it free

    Download it from this page and run the installer. It installs for your account with no administrator rights, because every default it changes belongs to your account.

FAQ

Questions about Default App Fixer

Is Vow Default App Fixer free?

Yes. You can make 5 default-app changes a day for free (the same change again that day costs nothing), and the health check, Repair, backups, undo, export and history are always free. Unlimited, a one-time $4.95 USD payment, adds any number of changes, the lock, Edge-only links in your browser, the link router and the Outlook & Teams link setting.

Why does Windows keep resetting my default apps?

Windows ignores a choice it can't verify and puts its own app back, which is when you see "An app default was reset". Updates and some apps also change defaults. The health check lists choices Windows is about to reset, and Repair fixes them for free.

Why do I still confirm some types in Windows' own window?

Since 2024 Windows protects web links, .htm and .html, .pdf and the Office types so only its own window can set them. Vow opens that window for you and watches until Windows has your choice. On some newer Windows 11 PCs every change goes through that window, and Vow detects this.

Can Windows Search and Widgets links open in Chrome or Firefox?

Yes, with Unlimited. When Windows starts Edge just for one of those links, Vow closes that start and opens the link in your default browser instead, with no administrator rights. If Edge is already open, the page may still appear there too.

Does it hack Windows or Edge?

No. It never turns off Windows' User Choice Protection, never patches Edge or hooks into it, and never writes protected settings behind Windows' back. Where Windows wants to ask you itself, Vow opens Windows' window.

What does the lock do?

A small helper watches your defaults and puts a changed one back within seconds, with a notification and a safety stop. Protected types get a one-click fix, or on Pro, Enterprise and Education PCs the Windows-enforced lock re-applies them at every sign-in.

Can I copy my defaults to another PC?

Yes. Back up all your defaults under a name, export them as a Vow file or as Windows XML in the DISM format, and import either on the other PC. Automatic backups are made before every change.

Is it safe to install?

Yes. It is made and published by XTO Pty Ltd, an Australian company. There are no ads, no bundled software and no account, it needs no administrator rights, and it uninstalls cleanly from Windows Settings, leaving your default apps as they are.
