Microsoft's horrendous Patch Tuesday update exposes the weak QA process for Windows

If you've been reading Neowin for the past couple of weeks, you probably have a good idea about the issues that the latest Patch Tuesday update has been causing. To Microsoft's credit, the company has been scrambling to fix these problems as soon as possible, releasing multiple out-of-band (OOB) updates, which is a bit unusual considering it's only been less than two weeks since KB5074109 made its way to the public.

Since its release, there has hardly been a day where people in online spheres haven't complained about a new issue that popped up. A day after release, we found out that Remote Desktop connectivity is broken on both supported versions of Windows 11, along with various SKUs of Windows Server. We noted at that time that this bug primarily impacted enterprise environments, which is basically Redmond's main cash-cow.

Shortly after, we learned that there is yet another bug in Patch Tuesday that does not allows PCs with Secure Launch enabled to shut down or hibernate, which is a pretty major nuisance. Although Microsoft did roll out emergency OOB updates to fix both of the aforementioned problems, it was clear at this point that this was not a well-tested update.

Next, we found out that the latest release is breaking a ton of apps too. This includes Outlook becoming "completely unusable", payroll and graphics applications not responding to user input, apps that interact with cloud storage services freezing, Notepad and Snipping Tool not launching, and more. January's Patch Tuesday had become a nightmare for IT admins and consumers at this stage.

Again, Microsoft was forced to release OOB updates to work around these problems, but the latest nail in the coffin of this month's update appears to be PCs not being able to boot at all. Wowzers.

There are multiple factors for consideration in this entire ongoing ordeal for everyone. For starters, while it has been taken to a new extreme this time, Patch Tuesday causing issues is nothing new - we write about them regularly. Second, a lot of the problems highlighted above are not related to niche use-cases that are difficult to test; in fact, most of them impact all supported versions of Windows in mainstream workflows. Finally, the latest rollout, along with the constant stream of half-baked OOB patches exposes major gaps in Microsoft's quality assurance (QA) process for Windows.

Although Microsoft has never made a concrete announcement in this regard, there have been reports over the past decade or so that the company has scaled back on its testing and validation processes for Windows in a major way. This includes "restructuring" and laying off members dedicated to Windows QA, and generally just relying on Insiders to do the testing for the operating system.

Of course, anyone who has been involved with the IT sector in any capacity knows that while end-users can act as an excellent source of feedback for pre-release software, they cannot be a drop-in replacement for dedicated QA teams which are tasked and paid to find bugs in the system and try and "break" software. Insiders don't have visibility over the backend code, they can't write automated tests to check edge-cases, and they definitely don't document or reproduce every bug they encounter. They shouldn't be expected to do that either.

While it's understandable that Windows is used in hundreds of millions of devices around the globe and it is extremely difficult, if not impossible, to validate the behavior of every configuration, the bugs present in recent Patch Tuesday updates impacting mainstream audiences (IT admins, enterprise customers, and general consumers) have exposed glaring holes in Redmond's QA process for its flagship OS.

Perhaps it is time for Microsoft to go back to the drawing board and figure out how it can make Windows more reliable, because the latest episode has proven that just sending pre-release software to a handful of end-users is not enough. There needs to be a dedicated QA team that is responsible for testing compatibility with associated software and hardware after each change, and there definitely needs to be some accountability regarding the state of Windows in general.

Of course, this is easier said than done. But from an external person's perspective, maybe it is time to put a little less focus on integrating Copilot with everything, and more on software that is used by almost a billion people around the world. The next Patch Tuesday update will land on February 10, but it remains to be seen what new headaches await us when that rolls out.
