What is the update of Win10 official version 10240?

On July 16th, Microsoft has pushed Build 10240 in the fast and slow channels of the existing Win10 preview version. This version is regarded as "the official version", so it has received much attention. Gabriel Aul gave the main changes in this version in the official Microsoft blog. It is obvious that this version of the Edge browser is basically mature, and the JavaScript benchmark performance far exceeds the Google Chrome browser and the Apple Safari browser.

The specific results are as follows:
• WebKit Sunspider: Edge browser is 112% faster than Chrome browser
• Google Octane: Edge browser is 11% faster than Chrome browser
• Apple JetStream: The Edge browser is 37% faster than the Chrome browser.
Microsoft said it hopes to see users have a faster and better experience in the Edge browser. After several versions of the improvements, the Edge browser is basically mature.
In addition, the Windows 10 version of the Office application has now removed the "Preview" text, changed to "Mobile", which is distinguished from the desktop version of the Office suite. It's important to note that this version requires an Office 365 subscription license, unless you are using a 10.1-inch or smaller device, but you can apply for a free trial. If you want to use completely free Office, you can choose Office Online. However, the OneNote Universal app is completely free on all devices.
