How to Enable or Disable Indexer Backoff in Windows

information   Information
By default, Windows will use the index when searching to give you faster search results. The search index only includes your selected locations. These locations can be filtered for what file types (extensions), file properties, and file contents you want indexed.

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

By default, the search indexer backoff feature will reduce indexing speed while rebuilding the index when there is user activity, and will automatically continue at full speed when no user activity is detected.

If indexer backoff is disabled, indexing will continue at full speed even when system activity is high.

This tutorial will show you how to enable or disable indexer backoff used to reduce indexing speed when there is user activity in Windows 7, Windows 8, and Windows 10.

You must be signed in as an administrator to enable or disable indexer backoff.
