Microsoft is optimizing the search algorithm for the Windows Search indexer to make Windows searches more efficient and less taxing on hardware.
This chang may be included in Windows 10 version 2004 (20H1) and may finally address the complaints of high CPU and disk usage in the OS.
Extensive research by Microsoft revealed that excessive disk and CPU usage are the two main general performance issues experienced by users.
The Windows Search service or search indexer powers Windows Search across all apps and files on a PC and Microsoft uses the search indexer to crawl your files, documents, pictures, videos, apps, and metadata to return results quickly when you trigger Windows Search.
While Windows Search indexer is important, it causes excessive disk and processor use. This in turn causes your PC to slow down.
According to Microsoft, Windows 10 version 2004 comes with a new algorithm to detect excessive disk usage and other performance issues. If performance issues are detected, Windows 10 may throttle any search indexing activity to reduce possibilities of slowdowns.
Microsoft says it will stop the Windows Search indexer service when CPU usage goes above 80% and disk usage goes above 70%. The service is also disabled when gaming mode is turned on or when the device’s battery charge is less than 50%.
Microsoft has already finalized the next major release and 20H1 could be deployed as soon as April/May 2020.
