Other updates for Insiders

Improving Windows Search

As Insiders know, over the releases, we’ve been continuing to work on improving search results based on your feedback. Including adding Enhanced search mode (adding an easy option to expand search across all folders and drivers) in 19H1, as well integrating Windows Search into File Explorer, to ensure more consistent results regardless of where you start your search.

In 19H1, we asked Insiders why they were turning off the search indexer. Your feedback helped us make improvements then and helped us focus on three key areas of improvement in 20H1: excessive disk and CPU usage, general performance issues, and low perceived value of the indexer.

Based on this, we’re introducing an algorithm that detects high disk usage and activity, so it can better identify peak usage times and manage the indexer accordingly. We’re also making changes for developers to prevent searches of certain repositories and project folders to improve disk usage.

Learn more about these features that we’ve been working on throughout 20H1 and get helpful tips and troubleshooting info to help you make the most of Windows Search in our Supercharging Windows Search article.

Knowns issues

BattlEye and Microsoft have found incompatibility issues due to changes in the operating system between some Insider Preview builds and certain versions of BattlEye anti-cheat software. To safeguard Insiders who might have these versions installed on their PC, we have applied a compatibility hold on these devices from being offered affected builds of Windows Insider Preview. See this article for details.

We’ve heard that Settings still isn’t available outside of launching via the URI (ms-settings:) for some Insiders and are investigating.

Some Insiders are reporting that after successfully installing printer drivers from the Optional Updates section, the same driver is still showing as available for install. We’re looking into the issue.

We’re looking into reports where, when certain external USB 3.0 drives are attached, they stop responding with Start Code 10 or 38.
