    How to Enable or Disable Indexer Backoff in Windows


    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.

    Starting with Windows 10 build 19592, the Windows Search Platform (Indexer) has been updated with improved logic to help find better times to perform indexing of your files and avoiding heavily indexing while you are using your machine. An improvement was also made to significantly limit the amount of times the service indexes your files for content that doesn’t have an impact on search experiences, and gives you a better experience on Windows.

    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.

    Windows 10 2004 has a bug and will occasionally not honor this setting. Weird.
