Microsoft generally releases new features to the Insider build previews, so that they could be tested before the features are rolled out to the public. In the recently released Windows 10 Insider Preview Builds something very interesting, especially for power users, has been noticed, it’s called the ‘ultimate performance’ mode. And it’s exactly what it sounds like – the highest performance setting in Windows.
Windows 10 Ultimate Performance mode
Microsoft has released Windows 10 Insider Preview Build 17101 (RS4) for Fast ring users, and Windows 10 Insider Preview Build 17604 (RS5) build for Skip Ahead users, and the former has been specifically designed to upgrade the experience on workstations running Windows 10 Pro by offering a new power scheme called ‘Ultimate Performance’.
As Microsoft notes in a blog, the ultimate performance mode, offers an “absolute maximum performance” and boosts raw speed to levels that are far ahead of what you can obtain from the existing High-Performance scheme.
“This new policy builds on the current High-Performance policy, and it goes a step further to eliminate micro-latencies associated with fine grained power management techniques. The Ultimate Performance Power plan is selectable either by an OEM on new systems or selectable by a user,” Microsoft writes in the blog.
In order to manually switch to the mode on your Windows 10 Pro machine, you need to switch to the Ultimate Performance scheme by going to Hardware and Sound > Power Options, or by simply running “Powercfg.cpl” after pressing Win+R key combination.
However, it is essential to note here that since the new policy reduces micro-latencies, it may adversely affect your hardware and make it more power hungry than what it was on the default balanced plan. And so, as Microsoft points out, the Ultimate Performance power policy is currently not available on battery powered systems.
Windows App permission
In addition to the new power scheme, the Windows 10 testing builds also reveals enhancements to the UWP File System Access by giving more controls to you to decide which UWP apps can access your full file system. There is a new Settings page for File System Access that you can access by going to Settings > Privacy to turn file system access on or off globally or select, which apps should use file system access.
This means, if a UWP app has the broad file system access restricted capability, you will receive a consent dialog prompting you to accept or deny the request.
Emoji design updates
Other than that, Insider Preview Build 17101 also includes some emoji design updates to align with the standard emoji characters. Plus, Microsoft will now allow you to find an emoji by keyword in over 150 locales.
The new Windows 10 Insider Preview Build 17101 (RS4) is available for Windows Insiders in the Fast ring, while the Windows 10 Insider Preview Build 17604 aka RS5 is specific to Windows Insiders who have opted into the Skip Ahead ring.
