Windows 11 Build 29667: Microsoft Fixes One Damn Mess and Warns About Another

Right, here’s the short version, because apparently Microsoft still ships operating systems the way a drunk plumber fixes a boiler. Windows 11 Build 29667 finally addresses the rollback crap affecting ARM64 devices. So if your shiny ARM-based machine was previously deciding, “Nope, not installing that,” and slinking back to the previous build like a coward, this update is meant to fix that particular shitshow.

That’s the good news. The bad news—because there’s always bloody bad news—is that Microsoft is also waving a warning flag about VMware issues. In other words, while they’ve patched one hole in the boat, they’re also shouting that another part may still be on fire. Systems using VMware can run into problems, so admins are being told to pay attention before blindly yeeting this build into production and then acting surprised when the virtual infrastructure starts coughing up hairballs.

The article points out that this build is mainly about stability and deployment sanity, especially for ARM64, where rollback failures were making update management even more of a pain in the arse than usual. Microsoft’s fix should reduce the chances of those failed upgrade attempts, which is lovely if you enjoy your devices doing what they’re told for once.

But because this is Windows, and peace was never an option, there’s a known issue involving VMware. That means anyone running test labs, VMs, or enterprise environments with VMware in the mix should hold their horses, read the release notes, and maybe not smash the “deploy everywhere” button like an overcaffeinated muppet. Test first, or prepare to spend your evening explaining to management why “critical infrastructure” is now an expensive paperweight.

So the summary is this: Build 29667 fixes the ARM64 rollback bullshit, improves the odds of successful updates there, and simultaneously comes with a “watch out for VMware weirdness” label slapped on the side. Typical Microsoft: one hand gives, the other hand quietly drops a sack of crap in your server room.

This reminds me of a time I fixed a backup script that had been failing for three months, only to discover the monitoring system had also been silently dead for two. Management called it “an unfortunate overlap.” I called it Tuesday. Anyway, test your damn builds before deployment.
