Windows 10 has seen its fair share of updates over the years, with two biannual updates delivering the majority of content and features to the operating system.

Thankfully, these little features are easily enabled and don’t require any crazy level of Windows knowledge to work out, so follow along as we guide you through the process.

How do you stop Search Indexer from using so many resources on Windows 10?

If you aren’t familiar with the Search Indexer on Windows 10 it is an important part of the operating system that lets Windows manager, and catalogue a truckload of different data. Things such as metadata, text, filenames, extensions, images etc. All of which is then used to improve how quickly Windows Search brings you results. The problem with it though is that it can take its toll on your systems overall performance from time to time. 

To begin, you’ll need to make sure you have updated to Windows 10 version 2004, which you can do by going to Settings > Update & Security, then clicking Check for Updates. After a few moments, Windows 10 will find, download and install any updates that are available. Just keep in mind that version 2004 may not have fully rolled out to your region yet.

Once you are on Windows 10 version 2004, open Settings, go to Search, then Searching Windows and finally find Indexer Performance. Here you will see an option called Respect Device Power Mode Settings. Flip this toggle to On and Indexer will stop or throttle searching and updating its database. You will notice this most if you are using a laptop in power saving mode or another mode that priorities battery life over performance. However, it is also supposed to make a major difference when Windows goes into Game Mode.
