Indexing the contents of your PC helps you get faster results when you’re searching it for files and other things. Learn how it works.
Indexing is the process of looking at files, email messages, and other content on your PC and cataloging their information, such as the words and metadata in them. When you search your PC after indexing, it looks at an index of terms to find results faster.
When you first run indexing, it can take up to a couple hours to complete. After that, indexing will run in the background on your PC as you use it, only re-indexing updated data.
Starting at least with Windows 10 build 18965, you can turn on or off having the search indexer respect device power mode settings. This will affect the indexer performance.
The Windows performance power slider enables you to quickly and intelligently trade performance of your system for longer battery life. As you switch between the four power modes to trade performance for battery life (or vice versa), Windows power settings are engaged behind the scenes. You are able to customize the default slider mode for both AC and DC, and can also configure the power settings, and PPM options, that are engaged for each slider mode.
This tutorial will show you how to turn on or off having the search indexer respect the device power mode settings for indexer performance for all users in Windows 10.
