Win10 official version of the U disk how to buy?

Microsoft recently confirmed that its latest operating system, Windows 10, will be sold through a USB flash drive, and users no longer need to use a DVD drive when installing the system.
The rumors that Microsoft will sell Windows 10 via USB sticks have been around for a few weeks, but the company has refused to publicly respond to Windows 10 physical installation media other than DVDs. Recently, however, users have found that the Windows 10 reservation page on the shopping site Amazon shows a U disk version. The page shows that the Home Edition Windows 10 is priced at $119.99 and the Professional Edition is priced at $199.99.
In response to media requests for comment, Microsoft did not specifically talk about Amazon's booking page, but for the first time confirmed that users will be able to install the system by purchasing a USB flash drive with Windows 10.








Windows 10 will also be sold through U disk, users will be able to purchase the U disk in various retail channels soon after the system is officially listed, Microsoft spokesperson told VentureBeat, "Windows 10 recommendations in the United States" Retail is the same as Windows 8.1.

As seen above, the page shows the seller as Microsoft. Currently, in addition to Amazon, Microsoft Online Store, Best Buy or other online retailers have not yet appeared on the Windows 10 reservation page sold through the USB flash drive.
In addition, the page shows the release date of August 16. The official release date for Windows 10 is July 29, and Microsoft also said it will be upgraded in stages, but this does not explain why the release date of the Amazon page will be delayed. One possible scenario applies only to the Amazon channel, and another possibility is that only Windows 10 sold through a USB stick will be delayed. After all, Microsoft said it was officially listed "after a while".

If users want to use the USB version and want to use Windows 10 as soon as possible, then you have two options. One is to order at Amazon and then wait for Windows 10 to ship for about two weeks, and the other is that you can wait for other retailers to start selling U disk version of Windows 10, or the delivery date will be earlier than August 16
