Windows 11 Release Preview (KB5020044) fixes high CPU usage in File Explorer and more

Windows Insiders on the Release Preview Channel are being updated to Windows 11 version 22H2 build 22621.898 (KB5020044). This build includes a fix for whenever a file is selected it could cause high CPU usage in File Explorer, as well as a fix for modern apps that refused to open among other important fixes listed below in the changelog.

Although this build doesn't come with any exciting new UI related features, Microsoft has now combined the Windows Spotlight feature that puts a new wallpaper from Bing on your desktop every day, with Themes on the Personalization page. There's also some OneDrive improvements such as storage alerts in the System Settings app, along with OneDrive subscription details in the Accounts page of the Settings app to further integrate Microsoft's services into Windows 11.

The full changelog is below:

• New! We gave Microsoft OneDrive subscribers storage alerts on the Systems page in the Settings app. The alerts appear when you are close to your storage limit. You can also manage your storage and purchase additional storage, if needed.
• New! We provided the full amount of storage capacity from all your OneDrive subscriptions. It also displays the total storage on the Accounts page in the Settings app.
• New! We combined Windows Spotlight with Themes on the Personalization page. This makes it easier for you to discover and turn on the Windows Spotlight feature.

Microsoft did not share any known issues with this build.

This build does not appear to include any staggered rollouts, as that is not mentioned in this month's Release Preview update, so all of the new OneDrive integrations, Windows Spotlight in Themes, and organizational messages feature should be available to everyone immediately after updating.
