Windows 10 KB4571744 (Build 19041.488) Full Changelog

Windows 10 Build 19041.488 is a huge update and it comes with a long list of fixes. For example, Microsoft says it has fixed an issue that could prevent users from reducing the size of an app window on some configurations.

Microsoft also noted that it has enabled support for 24-bit Dolby Atmos for Headphones and DTS Headphone: X in Windows 10.

The company has resolved an issue where Windows Update could become unresponsive when checking for updates. Likewise, Microsoft is also fixing an issue that causes File Explorer to stop working when you save raw images and browse their directories.

There are several other improvements bundled in this release, including an improved tablet experience for convertible or hybrid devices, enhanced Windows Hello enrollment page, and fix for an annoying issue that could increase the load time of some apps.

Defragmentation problem fixed

Windows 10 KB4571744 also fixes an alleged issue that could defrag your SSDs too often.

As we reported recently, a bug in Windows 10 May 2020 Update broke the Defrag utility app, which decided to defrag your SSDs little too often, potentially affecting the lifespan of your storage device.

Windows 10 Drive Optimizer

Normally, the app will optimize (defrag) SDDs on a default schedule (once a month) or one set by the user, which improves the performance of the drive. However, after Windows 10 2004 update, Defrag tool can end up optimizing your drives on every reboot, which could significantly shorten the lifespan of SSDs.

Windows 10 Build 19041.488

Fortunately, Windows 10 patch addresses both the defrag issue and incorrect reporting bug in Drive Optimize tool.

As we noted above, this is an optional update and it won’t install on your device automatically. If you skip it, you’ll still get everything that’s mentioned here in the next week’s Patch Tuesday update.
