Microsoft just dropped Windows 11 KB5121767, an emergency update that replaces the July 2026 cumulative update on PCs affected by unexpected shutdowns, poor performance, overheating, and battery drain. This update shows up as “2026-07 Update (KB5121767) (26200.8894) and is available for everyone, including those unaffected.
Microsoft says the new out-of-band update is recommended only for affected Dell PCs, but Windows Latest observed that it may automatically download and install on other PCs when a specific Windows Update toggle is enabled.
Microsoft hasn’t published the list of affected PCs yet, but Windows Latest has managed to obtain it from our sources.
According to our sources, the following Dell PCs are affected and should automatically receive today’s emergency update:
- Dell Pro Max 14 Premium MA14250
- Dell Pro Max 16 Premium MA16250
- Dell Pro Precision 7 14 PW714260
- Dell Pro Precision 7 16 PW716260
- Precision 5470, Precision 5480, Precision 5490, and Precision 5770
- XPS 17 9720 and XPS 17 9730
Although Microsoft recommends Windows 11 KB5121767 only for affected devices, Windows Latest observed that the update begins downloading and installing on all PCs where the “Get the latest updates as soon as they’re available” toggle is turned on.
If you have already installed it without experiencing any problems, you do not need to worry. However, this is another reminder to turn off the toggle if you do not fully understand how it works. Some of you may end up unnecessarily installing today’s out-of-band update because of how it is distributed and labeled.
Windows 11 KB5121767 released to fix shutdowns, overheating, but you don't need it unless you own these PCs
