New Windows driver blocks software from changing default web browser

Microsoft is now using a Windows driver to prevent users from changing the configured Windows 10 and Windows 11 default browser through software or by manually modifying the Registry.

@Klaxun @BleepingComputer I just wish gaming on Linux was further along
@BleepingComputer

lol It's called User Choice Protect Driver but It's only to protect Microsoft choices they forced on you
@marud @BleepingComputer they didn't say which users choice it was protecting
@BleepingComputer i would simply turn off updates and not deal with this
@BleepingComputer that's gotta violate competition law somewhere
@bermudianbrit @BleepingComputer As in they've gotten successfully sued by the US Government over literally this previously XD https://en.wikipedia.org/wiki/United_States_v._Microsoft_Corp.
United States v. Microsoft Corp. - Wikipedia

@nytpu @BleepingComputer well exactly what I was referencing
@bermudianbrit @BleepingComputer ironically the only plausible theory there is compliance with an EU law?
@krupo @bermudianbrit @BleepingComputer It doesn't apply in the EU. Everyone I know who is forced to keep windows going has moved to Ireland (virtually)
@BleepingComputer bloody hell! it's clear to see that M$$ has learned nothing since the browser wars of the 90s. they really want another anti trust litigation on their hands? they're treading a dangerous path. first by making windows 11 requirements artificially super high; then putting win ten updates behind a paywall that cost more than the OS in a lot of cases, and then this insanity? if I didn't depend on several windows programs I'd have switched to linux long ago.
@BleepingComputer apparently people didn't read or didn't understand the issue. This is about an application not being able to overwrite the default browser the user has selected. This is a good thing, not Microsoft being evil.
@schmitzel76 @BleepingComputer I can see that, and the article could be a lot more clear about that. It’s one thing to prevent users from changing this. It’s another to prevent tampering, of course.

@schmitzel76 @BleepingComputer no, I think people understand this issue all right.

Microsoft wants to prevent any kind of program or script to automatically change the default browser and pdf reader.

This would be something an admin wants to do to prevent usage of Edge throughout the company, or a tool that helps users to protect their privacy by changing several bad default choices that MS set up. You really want tools like privatezilla, win10debloater and so on that help users to switch all the spying default settings off in one go. This driver is meant to prevent or make such programs much harder to use.

@schmitzel76 @BleepingComputer so if I install Vivaldi, Vivaldi can't ask me if I want it to become the default browser, which was an extremely straightforward way to change the default browser. Instead, now I have to dive into settings menu to do something I could do with one click. Am I reading this correctly?
@oblomov @BleepingComputer that will still work as it currently is, as Vivaldi does not set itself as the default, but opens the Windows Settings panel for you.
@BleepingComputer This is against antitrust.

@BleepingComputer This driver is described as a "User Choice Protection Driver,"

Uh huh, that sounds double-plus-ungood
