The upcoming Windows 10 Version 2004 (20H1) feature update will fix an issue where Windows Search Indexer is causing excessive disk and CPU possession. In the latest preview of Windows 10 Build 19592 released today, it’s clear that Microsoft is making more detailed improvements to Windows Search Indexer to perform file indexes faster by optimizing logic.
Windows Search indexer provides a faster file search experience by creating indexes that users can use in file manager, taskbar search bar, and start menu. On Windows 10, Microsoft says it will index the start menu and user folders including documents, downloads, desktops, videos, and photos, so searches can quickly find and feedback search results.
The indexer often scans new files and applications on the computer. CPU and disk usage can increase during scanning and may result in a 100% utilization rate on low-end hardware.
In the Windows 10 Build 19592 update, Microsoft made adjustments to Windows Search to actively pause the indexer when you’re using the device. The company says it has improved its algorithm for automatically finding index edit times.
Windows Search also limits the number of times it indexes files for content that does not affect search results. Although these improvements will come in the second quarter of this year, Microsoft has also introduced a new algorithm for Windows search in the Windows 10 2004 update. The new algorithm detects overuse and other performance issues and limits search index activity to prevent system slowdowns.
