Windows 11 features a powerful, instant search bar that allows you to find documents, images, and emails almost instantly. It achieves this speed through a background process called “Indexing.” By default, Windows doesn’t just index the names of your files; it actively opens and scans the entire text contents of your documents (like Word files, PDFs, and text files) so you can search for a specific sentence hidden deep within a file. While incredibly useful, full-content indexing requires constant disk reads and CPU cycles, which can slow down older hard drives or drain laptop batteries. If you only ever search by file names, you can disable content indexing to improve performance.
How to Stop Full Content Indexing
You can adjust how deeply Windows scans your files by modifying the legacy Indexing Options.
- Click the Start Button on your Windows 11 taskbar.
- Type Indexing Options into the search bar and press Enter to open the classic control panel window.
- Click the Advanced button at the bottom of the window. (You may need administrator privileges).
- In the Advanced Options window, click on the File Types tab at the top.
- Look at the bottom section labelled “How should this file be indexed?”
- Select the top radio button labelled Index Properties Only.
- Click OK.
- A warning will appear stating that rebuilding the index might take a long time. Click OK to confirm.
Windows will delete its massive database of document contents and begin building a much smaller, faster index containing only file names, dates, and basic metadata. Your search results will still be lightning fast when looking for a file by its title, but you will save significant system resources in the background.
