Windows 10 Insider Preview Build 10525 released for the Fast Ring

Microsoft has released Windows 10 Insider Preview Build 10525 to the Fast Ring members of the Windows Insider Program.


This is the first preview build, released after the launch of the final build of Windows 10.

Windows 10 Build 10240, which is the current stable build available for all users, was the last Preview Build of the operating system, released to Insiders. It was released a few days before the final build of Windows 10, was rolled out on July 29th.

Microsoft has by popular demand, re-added the Windows Feedback back into the operating system. It was removed from the Preview Builds of Windows 10, back in July. The Feedback app will offer special surveys for Insiders, as well as some unique options, such as taking a screenshot, reproducing a problem, and more.

What’s new in Windows 10 Insider Preview Build 10525:


Microsoft has included some new customization options for the Start Menu, Acton Center, Taskbar, and Title bars.  You can now set Windows 10 to pick an accent color, and reflect it on the above mentioned areas of Windows 10. This option is not enabled by default, and can be enabled from Start >Settings > Personalization > Colors.

Memory Management:

Windows 10, has a new component in the built-in Memory Manager, called a compression store. This module stores an in-memory collection of compressed pages, which it will use to monitor the memory load. Once it detects a heavy load, it will compress unused pages, to prevent writing them to the disk, which in turn reduces the memory used by processes. This feature will make the system more responsive, for multitasking.

It is not a toggle or visible option, and is instead a part of the “System Process”, which you can find in the Task Manager. Naturally, due to its intensive monitoring, the compression store, happens to be the reason why the process consumes more memory.

Known issues in Windows 10 Insider Preview Build 10525:

The Mobile hotspot doesn’t work in Build 10525, and will fail to get an IP address, when you try to connect your PC to a mobile device’s network. Hence you will see a “no internet access” message.

The Movies & TV app, which you can find at the Windows Store, does not work, due to a bug in the video playback. A fix for this is required, and there is no word when it will be released.

Optional languages packs are not available for the build at the moment, and are expected to be made available later this week.

Here is the official announcement from Microsoft.


If you want to opt-out of the Windows Insider Program or re-join it, open the Settings App and navigate to Update and Security, and then on Windows Update. Click on Advanced Options, and then scroll down to “Get Insider Builds”, and select Get Started. You can also opt out of the Insider Preview Builds from this screen, and will need to reboot the system for changes to take effect.
