Microsoft's next big Windows 10 update is at the twilight stages of development and will arrive on compatible desktop computers next month.

Tech enthusiast Paul Thurrott reported on his official website that Microsoft will roll out the Windows 10 Fall Update in early November.

Codenamed "Threshold 2," the update carries several fixes and UI changes that were supposed to be included in the final version of Windows 10 back in July. These improvements include colored title bars for desktop icons, a spare Live Tiles column for the Start Menu and enhanced context menus.

The update also brings a native Messaging and Skype Video app to the Windows 10 operating system. The setup is undoubtedly in anticipation for the wider release of Windows 10 mobile devices as The Verge previously reported that Cortana will be updated with the ability to send SMS from PC to Windows 10 smartphones.

Improvements to the Edge browser and Media Creation Tool can also be expected.

As for the technicalities of the upcoming update, it can be directly installed from the RTM version of Windows 10 without users having to install prior updates. Moreover, Windows 7 and 8.1 users who have upgraded to Windows 10 after the Fall Update has been released will automatically get the Fall Update version of Windows 10. Its official OS version number is 1511.

The Fall Update can be accessed by navigating through Update & Security, which can be found in the Windows 10 Settings menu. It will have the exact same distribution method as a security update, meaning it will immediately install itself if users enable the Automatic updates setting.

The best case scenario would be the PC booting up one day and running on Windows 10 version 1511. To those who don't have the automatic updates setting turned on, the upcoming update bears the name "Windows 10 November 2015" in Windows Update.

As good as it seems, it's worth mentioning that users have to pay for Microsoft's latest operating system in order to use it permanently.

Windows 10 might seem as a free upgrade for now, but Microsoft CEO Satya Nadella explains that the temporary scheme is set in place to make sure Windows 7 and 8.1 don't become stagnant OS builds like Windows XP.

"There are two things we are really focused on; one is to really make sure Windows 10 is a fantastic upgrade experience for even Windows 7 customers, even on the desktop with a mouse and keyboard. It's familiar but you can get all this new value. And then we hope that one year promotional offer really helps a lot of Windows 7 customers move over," Nadella told TechRadar.

Basically, Microsoft wants users to move on to Windows 10 so it could eventually stop making OS-specific updates for Windows XP, 7, 8.1, etc.
