This practical guide walks through how to enable / disable the indexer backoff feature in, explains the main requirements, and highlights common issues that may appear along the way.

Indexer backoff feature in Windows

The index uses the Windows Search service and runs as a Searchindexer.exe process in the background. The index will rebuild automatically and update changes made to the included placements since the last index rebuild to increase the accuracy of the search results.

By default, the indexer backoff feature will slow down while rebuilding the index, if there is user activity, and will automatically resume at maximum speed when no user activity is detected.

If the indexer backoff feature is disabled, indexing will continue at maximum speed, even during high system performance.

Beginning with Windows 10 build 19592, Windows Search Platform (Indexer) has been updated with improved logic, helping to find a better time to do file indexing and avoid more indexing when you're on your computer. An improvement was also made to significantly limit the number of times the service indexes files for content with no impact on the search experience and to give you a better experience on Windows.

This guide will show you how to enable or disable the indexer backoff feature that is used to slow down indexing during user activity in Windows 7, Windows 8, and Windows 10.
