Microsoft emergency patch fixes Dell Windows 11 crashes — may hit non-Dell PCs too

Full text

Windows 11's July update was blocked from certain Dell laptops due to nasty issues with unexpected shutdowns and poor performance

Microsoft just issued an emergency patch to fix those problems, so the PCs in question can install the latest update

However, that patch might end up installed on non-Dell PCs if the user has enabled the option to get the latest updates as soon as possible

Windows 11's latest (July) update was blocked from Dell PCs as it was buggy on those systems, but the good news is that it's now fixed — but there's an additional wrinkle to be aware of here for those of you who don't own a Dell machine.

Windows Latest reports that Microsoft just deployed an emergency update (KB5121767) which fixes the problems with certain Dell laptops with Intel CPUs, which include unexpected shutdowns and generally poor performance (including running sluggishly and overheating, as well as increased battery drain).

Those with an affected Dell laptop — and that apparently includes some XPS models, as well as Dell Pro and Precision (business) notebooks, and possibly others — should install the emergency patch. As Microsoft makes clear , you'll find it under optional updates, which is reached via 'Advanced options' in the Windows Update panel.

However, the wrinkle that I mentioned is that Windows Latest observes that it's possible some Windows 11 PCs that aren't Dell laptops may automatically grab and install this update — if they have the 'Get the latest updates as soon as they're available' toggle on.

Analysis: a notable side effect

(Image credit: Future) This feature is one that people turn on in the hope that they'll get Windows 11 updates, and more to the point, new feature rollouts, more quickly (there can be quite a wait for certain features to arrive, such as the Start menu revamp from last year , which some folks still haven't received even now).

So, bear in mind that if you've enabled this option, you may get certain updates automatically — like this emergency patch — when you don't actually need them on your PC. It doesn't help that this particular update is confusingly named, being called '2026-07 Update (KB5121767) (26200.8894)', which could leave you wondering what on earth it is exactly (until you look up the codename KB5121767).

At any rate, if you're not happy with this situation, to turn off 'Get the latest updates as soon as they're available' you need to head to Windows Update (in Settings) and adjust the relevant slider (at the top of the 'More options' panel).

Why is this option configured in this way? It seems especially odd in this case seeing as Microsoft tells us: "This OOB [emergency] update is only recommended for devices affected by this issue." That said, seemingly it doesn't do any harm to a non-affected PC (whether a Dell model, or not) if it does end up with this emergency patch installed.

At any rate, if you do enable the option to get the latest updates, just don't forget that this can have side effects, such as installing optional updates that you don't actually want. It would be a better idea if, in these cases, Microsoft simply flagged these updates as available, rather than having them install automatically.

It's also worth noting that this isn't the first time Dell laptops have run into trouble with Windows 11 recently, as last month an update to the firm's SupportAssist app left some notebooks crashing every half an hour or so .
