Vow Default App Fixer shows what opens your web links, PDFs, photos, videos, music and documents on one screen, and changes every type an app handles in one click. It finds the choices Windows is about to reset, fixes them for free, and with Unlimited puts your defaults back the moment anything changes them. No hacks, no ads, no account.


The problem
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.
Windows quietly ignores some choices and puts its own app back, usually after an update, with nothing but a brief notification.
Settings makes you change .mp4, .mkv, .avi and a dozen more one by one, then hunt through a list of hundreds.
Links from Windows Search, Widgets and News open in Edge even when another browser is your default.
Uninstall an app and its file types can be left pointing at nothing, so Windows asks every single time.
Quick fixes from forums switch off Windows' protection or hook into Edge, and can stop working after the next update.
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
Every file and link type on one screen, set the way Windows itself does it, so the choice sticks.
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.


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.


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.

FAQ
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.

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.
