Windows 11 Update KB5079473 Enhances File Explorer Speed for ‘This PC’ and Multi-Drive Searches

In a subtle yet impactful move, Microsoft has rolled out the Windows 11 KB5079473 March 2026 Update, aimed at enhancing the search functionality within File Explorer. This update promises improved performance, potentially easing the search experience for users, particularly on certain PC configurations.

The update focuses on making searches within File Explorer more reliable. As a result, many users may find themselves retrieving files more swiftly, whether performing searches across multiple drives or within the ‘This PC’ interface.

Although the improvements may seem minor at first glance—often overlooked due to their placement in release notes—they represent a significant enhancement in user experience. It’s worth noting that quantifying reliability fixes poses challenges, as their effects are best measured through daily usage rather than direct benchmarks.

According to Windows Latest, the effectiveness of the File Explorer search function is largely influenced by factors such as indexing, folder structure, file history, and drive configuration. Consequently, users may notice a marked reduction in confusion and unreliability when using the search feature.

Despite its significance, many users might miss this update as it is discreetly mentioned in the release notes. Microsoft highlighted this enhancement, stating, “This update improves File Explorer search reliability when searching across multiple drives or ‘This PC.’” Learn more here.

Incorporating improvements for searches within ‘This PC’ is particularly noteworthy. This feature presents unique complexities, as searching in ‘This PC’ extends beyond specific folders or drives to encompass all folders across all available drives.

Search indexing in Windows 11 — You can control indexing from Windows Search settings

Based on observations by Windows Latest, the previous experience with File Explorer often required several minutes to retrieve files that weren’t recently accessed, particularly those older than a few weeks. Users have reported instances where the search function could freeze, leading to frustration. Although Microsoft has not made definitive promises regarding these issues, the statement regarding improved reliability hints at potential positive changes.

In personal testing conducted over the last couple of days, I found that the search function in File Explorer displayed fewer inaccuracies with identical queries. However, there remains a noticeable lag when searching for more complex files.

Additional Enhancements: Faster Storage Scanning and Printing

Beyond File Explorer, the Windows 11 KB5079473 update also brings speed improvements to the Storage Settings, expediting the temporary files check-up during drive scans. Nevertheless, it still appears to overlook certain Windows Update files due to a recent activation of the administrator pop-up for Storage settings.

Moreover, the update has optimized the Windows printing service, ensuring that it does not slow down system performance during print jobs.

Overall, the Windows 11 KB5079473 update seems to be a positive step forward, enhancing user experience in several key areas. I will continue to share my findings as I delve deeper into its features.
