A number of Winaero readers have faced an issue in Windows 10 that after a few build upgrades, Search becomes slow and consumes a notable amount of CPU power. It happens every time the user searches for a file or document using the Cortana UI/Search text box in the taskbar. Here is a solution we found to make search fast and responsive again.
As you may be already know, search results in Windows are instant because they are powered by the Windows Search indexer. It is not new to Windows 10, but Windows 10 uses the same indexer-powered search like its predecessors although it uses a different algorithm and a different database. It runs as a service that indexes file names, contents and properties of file system items and stores them in a special database. There is a designated list of indexed locations in Windows, plus Libraries which are always indexed. So, instead of performing a real-time search through files on the filesystem, the search performs a query to the internal database, which allows showing results immediately.
When you search for some folder or file which is not located in an indexed location, the search is slower by several orders of magnitude. That's exactly what was happening in this case after upgrading the Windows 10 build. Some locations which need to be indexed were missing from the search index.
If this slow Windows 10 search issue affects you, follow these simple instructions below to easily fix it.
- Open the Control Panel.
- Go to
Control Panel\Personalization and Appearance
- There you will find an icon named File Explorer Options:
- Open File Explorer Options, switch to the View tab and turn on the display of hidden items as shown in the screenshot below. Refer to this article to understand how to show hidden items.
- Now, open Indexing Options by typing indexing options in the search box of the Control Panel, and then click the settings item Indexing Options.
- Open the Indexing Options applet. The Start menu folder should be in the list of indexed locations.If you are having the issue of very slow search results, then in such a case, the Start Menu folder might not be in the list of indexed locations.You should add this location back.
- Click the 'Modify' button.
- Add the following folder:
- Repeat step #6 for the following location:
C:\Users\you user name\AppData\Roaming\Microsoft\Windows\Start Menu\
That's it. Give Windows a few minutes to index these locations. Then your search in Windows 10 will be fast again!
