Microsoft releases Windows 10 Redstone 4 Build 17101 for Fast & Build 17604 for Skip Ahead

Microsoft have released new builds for Windows Insiders on the fast ring. Build 17101 is for the non-skip ahead machines and 17604 for the machines opted into the Skip Ahead builds. Going forward this will mean devices on the normal fast ring will continue to receive Redstone 4 builds and the skip ahead machines will receive Redstone 5 builds.

As we are getting close to the release of Redstone 4 there are not that many changes. There are new emojis and a new power/performance mode and the ability to opt into preview version of some of the standard Windows 10 apps:

A new power scheme – Ultimate Performance: Demanding workloads on workstations always desire more performance. As part of our effort to provide the absolute maximum performance we’re introducing a new power policy called Ultimate Performance. Windows has developed key areas where performance and efficiency tradeoffs are made in the OS. 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.

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. To do so, you can go to Control Panel and navigate to Power Options under Hardware and Sound (you can also “run” Powercfg.cpl). Just like other power policies in Windows, the contents of the Ultimate Performance policy can be customized.

As the power scheme is geared towards reducing micro-latencies it may directly impact hardware; and consume more power than the default balanced plan. The Ultimate Performance power policy is currently not available on battery powered systems.

Here are the other changes and known issues:

General changes, improvements, and fixes for PC (Build 17101)

• We fixed an issue from the last flight were some PCs failed to resume from hibernate (requiring a hard reboot to recover).
• We fixed an issue resulting in 3 and 4 finger gestures on the touchpad being unresponsive in the last two flights.
• We fixed an issue after upgrading to the last flight where Start didn’t work for Insiders who’d had HomeGroup added as a folder to appear on Start.
• We’ve updated the touch keyboard so that if you try to shapewrite in an unsupported text field or when the typing resources aren’t installed, you won’t see the shapewriting trail as you swipe your finger over the keys.
• We fixed an issue where the touch keyboard showed an English layout with no IME on/off key when an East Asian keyboard is the only input method on your system.
• We fixed an issue where if you install a font product from the Microsoft Store, then later install a new build (feature update), the Store package will remain installed, but the fonts within the package are not installed. Until this is fixed, the temporary workaround is to uninstall the product from the Apps page in Settings, then re-acquire the product from the Store.
• We fixed an issue where the touch keyboard might stop invoking automatically after locking the PC and then unlocking the PC by using the touch keyboard to enter your PIN or password.

• We fixed an issue that could result in the labels for files on the desktop overlapping their icons.

• When your volume is muted, the volume icons in the Sound Settings page will also now appear muted.
• If you click the Reset button on the App volume and device preferences page, it will now also reset any app specific volumes you’ve set back to default (100%).
• We fixed an issue resulting in app updates failing in the Microsoft Store with error 0x80070057 in recent builds.
• We fixed an issue resulting in app updates failing in the Microsoft Store with error 0x803FB005 in recent builds.
• We fixed an issue where bringing up Game bar using the Xbox button on an Xbox One controller didn’t work in some games.
• We fixed an issue where in the text box for the Mixer stream title using non-character keys (e.g. Tab, Delete, Backspace, etc.) might cause the game to hang for a few seconds.
• We fixed an issue where keyboard and mouse input might not work correctly in the Game bar when playing a first person game (e.g. Minecraft).
• We fixed an issue where in some games—such as Destiny 2 and Fortnite—mouse and keyboard input would still go to the game while Game bar was open.
• We fixed an issue during first shutdown/boot, or reboot, where for some users the device goes into a boot loop and the OS never loads.

Known issues (Build 17101)

• We have observed seeing longer-than-normal delays during install at the 88% mark. Some delays are as long as 90 minutes before moving forward. Please be patient as the install will complete successfully.
