Windows 11 users may soon notice File Explorer search getting quicker while using less RAM, thanks to a behind-the-scenes change Microsoft is currently testing in Insider builds.
Microsoft recently rolled out Windows 11 Insider Preview Build 26220.7523 to the Dev and Beta channels, and one of the most practical upgrades targets File Explorer. While the update includes general fixes such as improved reliability and better handling of system and secondary drive locations, the standout improvement is aimed at search performance and efficiency.
The key change is that File Explorer will stop doing duplicate file indexing operations. In simple terms, Windows Search can sometimes end up scanning and indexing the same paths more than once. With this update, File Explorer is designed to skip duplicate locations and rely on a single, consolidated index instead. The result should be faster searches and reduced system resource usage during file operations.
Even if File Explorer search isn’t usually the biggest RAM hog on most PCs, removing unnecessary indexing work can still make a real difference in day-to-day use. This kind of optimization can improve overall responsiveness, especially for people who search frequently across multiple folders, libraries, or drives. Less redundant background work also means fewer moments where File Explorer feels sluggish when you’re trying to locate files quickly.
Right now, the feature is being delivered through a controlled rollout method often described as “toggle on,” meaning not every Insider will get it at the same time. Those who do receive it should notice the improvement without needing to change anything manually. After Microsoft finishes testing and confirms stability, the plan is for the feature to be enabled by default and eventually make its way into regular Windows 11 stable releases.
For anyone who relies heavily on File Explorer search—whether for work documents, downloads, photos, or project folders—this is a small Windows 11 update that could have an outsized impact: quicker results, smoother browsing, and a little more breathing room for system memory.
