Windows 10X is now officially over, and Microsoft is now planning to bring its best bits into Windows 10.

“Instead of bringing a product called Windows 10X to market in 2021 like we originally intended, we are leveraging learnings from our journey thus far and accelerating the integration of key foundational 10X technology into other parts of Windows and products at the company,” confirms John Cable, head of Windows servicing and delivery.

- Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) updating performance improvement to support remote work scenarios.

Microsoft typically delivers a big major update of Windows 10 during the springtime, with a smaller one in the fall. The company has reversed that cadence for 2021, so the update that will likely arrive in October will be full of changes.

The next major update will include new system icons, File Explorer improvements, and even the end of Windows 95-era icons. Microsoft has some even broader visual changes arriving in Windows 10, as part of a “sweeping visual rejuvenation of Windows.” The October update will also fix the rearranging apps issue on multiple monitors, add the Xbox Auto HDR feature, and even improve Bluetooth audio support.
