Microsoft tests File Explorer search optimisation to reduce RAM usage in Windows 11

Microsoft is currently engaged in a series of understated yet significant enhancements to the Windows 11 File Explorer, focusing on alleviating its considerable appetite for system memory. These adjustments are presently being trialed in the latest Windows Insider builds, with the primary objective of optimizing the file manager’s search functionality. This initiative specifically targets the excessive RAM and CPU consumption that frequently occurs when navigating through extensive folders.

This update is appearing in Windows 11 Build 26220.7523 and above

At this stage, the updates are exclusive to participants in the Insider preview program. The essence of the improvement lies in a more efficient approach: Microsoft aims to prevent File Explorer from redundantly executing the same indexing tasks repeatedly, a notorious drain on system resources for years.

In a recent communication, Microsoft highlighted that it has refined the search procedure by “eliminating duplicate file indexing operations.” This adjustment means that Windows will no longer rescan the same files multiple times during a search, a straightforward yet effective solution that promises to enhance the overall experience while minimizing the strain on hardware resources.

It is important to note that File Explorer does not operate its own search engine; instead, it relies on the built-in Windows Search Indexer. Although this indexer is designed to be efficient, it often falls into a cycle of redundant tasks, leading to unnecessary spikes in CPU and RAM usage. By eliminating these “double-checks,” Microsoft is effectively lightening the overall system load, a welcome development for users operating on laptops with limited memory.

Beyond the technical plumbing, Microsoft is also continuing to tidy up the File Explorer interface

In addition to backend improvements, Microsoft is also refining the File Explorer interface, particularly the right-click context menu. Recent tests have revealed that several less frequently used options—such as “Copy as path,” “Compress to,” and image rotation tools—are being relocated into a dedicated sub-menu.

Depending on the version of the test, this new sub-menu is either labeled “Manage file” or “Other actions.” The intent is clear: to declutter the main menu, ensuring that essential functions are easily accessible without being obscured by a plethora of specialized tools that may only see infrequent use.

While these updates are still undergoing refinement in the Insider channels, a broader rollout is anticipated soon. Microsoft is expected to begin distributing these enhancements to all users around late January or February. If all goes as planned, the next Windows update could transform file searching into a quieter endeavor, while simultaneously streamlining the desktop experience.
