Microsoft's supercharged Windows 10 'Ultimate Performance' takes aim at high-end PCs


Up to now, Fast Ring and Skip Ahead have been identical, but this release sees a divergence representing how close we are getting to an announcement of a Spring update to Windows 10.

The company just revealed the new Ultimate Performance power plan, coming in the latest build of the Redstone 4 (RS4) of Windows 10. The new scheme is touted to eliminate micro-latencies that are linked with the default power management techniques. In both new test builds, Microsoft made changes to Windows App permissions, giving users more control over which Universal Windows Platform apps can access their full file systems.

This isn't the only exciting feature bundled into the Windows 10 Insider Preview Build.

The new power plan is still at the experimental stage but has been released as part of Windows Insider Builds 17101 and 17604. Insider Preview Build 17101 is specifically created to upgrade the experience on workstations running Windows 10 Pro by offering a new power scheme called "Ultimate Performance". If you aren't up for bugs, you can opt out of Skip Ahead back to the Fast ring.

In this case, Ultimate Performance is generally not built for gamers, as most would generally run consumer grade hardware and run a commercially available version of Microsoft's operating system. Only a small number of Windows 10 devices might encounter error 0x80070bc2 or 0x80070422 when attempting to install the cumulative update.

You can also revert back to using the standard version of an app by going to the Settings or About page and hitting the Leave preview button.

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. Over time, we've amassed a collection of settings which allow the OS to quickly tune the behavior based on user preference, policy, underlying hardware or workload. The new Windows 10 Ultimate Performance mode is an addition to the changes that were already announced. It will not be available on battery-powered laptops.
