When Teams Decided Not To Be A Teamplayer…

February 22, 2026

Laptops misbehave in every country on earth: from kitchen tables in United Kingdom to cafés in France, home offices in United States, and apartments in Japan, the humble machine has a universal talent for picking the worst possible moment to throw a tantrum. So when mine decided to stage a full-blown rebellion this morning, it felt less like a local inconvenience and more like joining a global club of people staring at a frozen screen, wondering what on earth just happened.

The day began with what looked like a routine Windows update; annoying but essential. We have all been there. You click “update and restart,” wander off to hang out the washing (yes it’s actually sunny outsidea and 12C !), and return expecting everything to be brighter, shinier, and marginally more secure. Instead, the machine refused to boot to the desktop. Instead, it kept turning itself off … argggghhhh!!
You can imagine the various permutations going through my head: had the battery died, had I opened too many apps at the same time… had I not spoken nicely to AI this morning and it was taking its revenge?

After a bit of sensible troubleshooting, a little patience, and some methodical problem solving, the culprit revealed itself: Microsoft Teams. Specifically, the version bundled and tangled up with the latest Windows update. Once Teams was removed, the laptop returned to life as if nothing had happened. Calm restored.

What actually happened here is a familiar pattern. Large Windows updates often adjust system components, background services, and login processes. Apps that run at startup or integrate deeply with the system can get caught in that shuffle. Teams is one of those apps. It likes to start automatically, sync in the background, and tie itself into user profiles. If an update changes something in that chain, Teams can hang, crash, or stall the login process entirely. The result can be a system that appears stuck or refuses to load the desktop.

The warning signs are subtle but consistent. A long delay on startup. A black screen with a spinning wheel that never quite gets anywhere. Or a login that appears to work but never delivers you to your actual desktop. If you have recently updated Windows and you use Teams, it is worth considering it as a potential cause if something feels off.

The fix, thankfully, is usually straightforward if you know where to look. Boot into safe mode if needed, disable Teams from start up and restart. In many cases, that is enough to break the loop and let Windows load normally again. You can then delete Teams if you, like me, only had it installed because local government departments refuse to use anything else.

There is a wider point here about modern software ecosystems. We rely on a stack of updates, background services, and integrated apps all behaving themselves at once. Most of the time they do. Occasionally one decides to have a moment, and everything else gets dragged into the drama. It is not usually catastrophic, but it is inconvenient enough to derail a morning.

The practical takeaways are simple. After any major Windows update, keep an eye on startup behaviour. If something is not right, think about recently updated or auto-starting apps. Teams is a common one. And if your machine refuses to reach the desktop, safe mode and selective app removal can often get you back on track without needing a full system reset.

In short, if your laptop suddenly develops a flair for theatrics after an update, do not panic. Make a cup of tea, approach it calmly, and remember that sometimes the problem is just one over-enthusiastic app trying to run the show.
