Search for files on your Windows 10 PC: How the new search works


The Windows file search works fine and is highly customizable: here’s how to set it up and use it to the fullest.

We greatly appreciated the search functionality of Windows 7. If correctly configured, it allowed you to search for a file of interest starting from its name and allowed you to search for files by analyzing their contents.

With the advent of Windows 10, this functionality has been a bit lost initially, and the search box has been closely linked with the digital assistant Cortana.
With the Windows 10 update 1903 dating back to May 2019, Microsoft has set things right: as we saw in the article What’s new in Windows 10 May 2019 Update, with the latest Plus, feature updates for Windows 10, the operation box of research was separate from that of Cortana.

You can search for files on your Windows 10 PC without the search being limited to the contents of a handful of system folders.

To check the Windows 10 you are using; we suggest you press the Windows + R key combination then type winver. Make sure you are using at least version 1903: if you are using previous versions of the operating system, update with Media Creation Tool or with the Update Assistant, both of which can be downloaded from Microsoft servers.

Normally, the search for Windows 10 – even with Microsoft’s update in May 2019 – is limited only to searching for the files contained in the “collections” ( Documents, Downloads ) and on the desktop.

Typing Windows Search Settings in Windows 10 May 2019 Update and later versions, a window similar to the one shown in the figure will appear.

If you do not remember a file’s name but one or more phrases contained in a document, Windows 10 will be of great help and will allow you to find documents without using third-party programs to search.

Under Indexing Status, the number of files indexed by Windows 10 will grow rapidly (slower when the user uses the system; in this case, the message ” Indexing speed decreased by user activity ” will appear ).

By default, as you can see by scrolling the window’s contents until you find Excluded folders, the feature will refrain from indexing Windows folders and other system directories.

If you had saved the data in a drive other than the one on which Windows is installed (more than reasonable choice), we suggest checking that the drives containing the data are not excluded.

If Windows 10 Search finds no

If even the new search function does not find the elements you are looking for (switching from one mode to another it happened to us …), we suggest you click on Advanced settings of the search indexer then on Advanced.

Windows 10 Search negatively impacts system performance. How to speed up indexing

The indexing activities performed by the Windows Search feature are minimized when the system is busy with some other operation (” Indexing speed decreased by user activity ” message seen above). This is a choice that aims to prevent the work carried out by Windows Search from impacting too strongly on the machine’s performance.

This behavior has been further improved in Windows 10 version 2004 (May 2020 update) to minimize the CPU’s impact, especially on systems that use traditional hard drives (not SSDs): Windows 10, lower CPU, and faster system thanks to improved indexing.

In Windows 10 May 2020 Update (version 2004) and later, you can type Windows Search Settings in the operating system’s search box and then set the Indexer Performance option to Enabled.

Once the Indexer performance option is activated, the Windows 10 feature that indexes files and folders in the background will stop its activity, including updating the database, at certain times, for example, when the device is in power saving mode, low consumption, or in-game mode.

The same behavior, aimed at optimizing system performance and reducing energy consumption, is maintained when the processor is stressed over 80% or when the disk usage goes up over 70%.

sc stop WSearch
sc start WSearch

In the Windows Search screen, you will now see the phrase ” Indexing in progress. The search results may not be complete during this operation .” However, overall system performance will be degraded until file indexing is complete.

To reactivate automatic indexing with reduced consumption of machine resources (default behavior), just double-click on the

Activate_Indexer_Backoff.reg file, then open PowerShell again with administrator rights and type the usual commands to restart the Windows Search service:

sc stop WSearch
sc start WSearch
