Windows Insider Build 26120.3073: Enhanced Search, File Explorer Fixes & More

  • Thread Author
Microsoft has dropped yet another juicy update for Windows Insiders! If you're subscribed to the Dev or Beta Channels, say hello to Build 26120.3073, also known by its less glamorous name, KB5050090. As of now, this is an optional update for Beta testers, but Dev Channel users are getting it hot out of the oven. This update boasts some exciting improvements for Windows 11's Search capabilities, squashes long-standing bugs in File Explorer, and even begins rolling out some features exclusive to Copilot+ PCs. Here's everything you need to know, decoded and expanded just for you.

Highlights: What’s Cooking in Build 26120.3073?

1. Search Gets Smarter (And Prettier?)

The update supercharges Windows Search, making it smarter and more intuitive—especially if you’re on a fancy Copilot+ PC. You can now perform deep cloud photo searches using semantic indexing. For instance, if you type "summer picnics" or "European castles", Windows can fish out files from your OneDrive photos that match your description.
To put it simply, Windows Search leverages AI to analyze the semantic meaning of your query (fancy speak for "what you’re really asking for") rather than just matching specific keywords. Semantic indexing narrows down results based on the intent behind queries like "Photos of me at the beach." Neat, right?
  • Limitations:
  • This improved search capability is currently limited to Copilot+ PCs.
  • Only available for photos on OneDrive linked with your personal Microsoft account—support for workplace or school accounts (Entra ID) is still limited and mostly text-based.
  • The visual sparkle and underline effects in the Search bar? Missing for now but expected soon.
What about Intel or AMD machines? If you don’t have a Snapdragon-powered Copilot+ PC, this feature isn’t ready for you just yet, but Microsoft promises it’s "coming soon."

2. File Explorer: Hangs and Bugs Finally Fixed

Let’s face it—File Explorer has been the Achilles' heel of Windows 11. From lags to memory leaks, it always seemed to be just short of perfection. With KB5050090, Microsoft aims to change that with a list of significant fixes, including one for the infamous address bar bug.
  • Major Fixes to File Explorer:
  • Fixed hangs or delays while browsing folders filled with media files (finally!).
  • Addressed an issue where minimized File Explorer windows wouldn’t render properly upon restoring.
  • Drastic improvements in search responsiveness within File Explorer.
  • Fixed memory leaks related to predictive input suggestions.
For casual users, File Explorer is smoother than ever. For power users juggling extensive directories filled with media or large file dumps, the system won't crumble under its own weight anymore.
Pro Tip: If Explorer is still slow to close using the X button, Microsoft notes this could remain an issue for some Insiders on this build.

Copilot+: The AI Assistant Gets New Features

We’re starting to see Microsoft lean hard into Copilot+ as more than just the next-gen assistant. With KB5050090, Windows brings enhanced AI-driven search functionality, new features to Paint (!), and some specific fixes tailored to Snapdragon systems.
The Headliner: Paint Copilot
Yes, even old-school Paint is getting a glow-up with features like generative erasing, background removal, and even "Cocreator for images." Copilot will assist in tasks like creating image edits or completely removing unwanted objects. While this is still experimental territory, the AI-assisted menu feels like a nod to Adobe Photoshop’s AI ambitions.

It’s Not All Sunshine: Known Issues Lurk

Even with its bells and whistles, KB5050090 isn’t 100% flawless. Microsoft has acknowledged a few gremlins:
  • High CPU Usage: After opening the "Performance" tab in Task Manager, some users report excessive CPU usage by the DCOM Service Process.
  • Settings Crashes: The new Settings homepage for commercial PCs under enterprise management is prone to unexpected crashes when toggling through specific areas (especially personalization options).
  • Slow Shutdowns on Some Devices: If your PC takes a tad longer to shut down than usual with a controller connected, this is a known issue being addressed.
  • Battery Icon Mishaps: Those using custom color modes like dark on white may notice color distortion in the redesigned battery icon.
Got any of these bugs? A restart can help smooth things out temporarily until future updates land.

Jumping Channels: Last Call for Beta Users

A pivotal announcement tucked into this update is the final opportunity to switch between Dev and Beta channels. Microsoft plans to bump Dev users to builds with higher numbers as early as next month. And heads up—those newer builds? Likely to be less stable than the current versions.
If you’re on the Dev Channel but prefer a safer ride, now’s your time to hop onto the Beta Channel before the drawbridge closes.

New Features for Enterprise (AKA Office Warriors)

For Introverts business users still rocking managed commercial Windows PCs, this build introduces some enterprise-led goodies:
  • Microsoft Accounts on Enterprise PCs: Commercial setups that integrate workplace and personal accounts now see clear indicators of both.
  • Settings Homepage: Adds enterprise-specific tiles like Device Info and Accessibility Preferences tailored for IT-administered systems.
In other words, IT admins, this one’s for you.

A Quick Recap: Should You Install KB5050090?​

For Windows enthusiasts and Insider Program members, this build is like a jam-packed buffet of features with some caveats:

Pros:​

  • Smarter, AI-driven search capabilities let you search the cloud like a pro.
  • File Explorer feels robust with fewer crashes, more consistent rendering, and improved memory handling.
  • Copilot is here to change how we interact with both images and structured searches.

Cons:​

  • High CPU usage bugs and incomplete Copilot+ integration for AMD/Intel systems mean some may have to wait for a polished version.
  • Known issues may bother gamers or users relying heavily on HDR and Remote Desktop.
Remember, Beta Channel users can skip this optional update for now, but early adopters in the Dev Channel should absolutely dive in.
