Microsoft has been releasing new 20H1 builds more frequently nowadays, though the builds have been quite minor in terms of new features, often only including general fixes and no new features.
Today’s build is pretty similar, and it includes only one new feature. Microsoft says the company is introducing a new algorithm for the indexer in Windows Search that makes it more efficient in terms of CPU and disk usage. The company said it carried out extensive research with Insiders over the last year to identify critical problems in the Windows Search indexer that led to some Insiders disabling Windows Search completely. And so, Microsoft simply started asking Insiders within Windows to give some feedback on why they disabled the feature as soon as they turned off Windows Search.
And the main reasons turned out to be excessive disk usage and general performance issues.
The new system for the indexer makes it so the indexer stops searching your files in the background or throttles it down at peak usage times. That includes things like when gaming mode, power savings mode, or low power mode is turned on, or when CPU usage goes above 80%, or when disk usage goes above 70%. Essentially, the new algorithm makes it so the indexer adapts to your computer’s usage and battery health, so it doesn’t disrupt everything else you are trying to do.
There’s also a number of general fixes and improvements in the update, so make sure to checkout the full changelog here.
