According to information obtained by Winfuture.de, Windows 10 may be sold on USB drives in addition to DVD disks.
The unnamed source of Winfuture’s information also reports that both the 32 and 64 bit versions of Windows 10 will be available on the thumb drive, and the customer will be able to choose which version to install. This is an added advantage of placing the Windows 10 install files on a USB drive as historically DVD copies will solely be for either a 32 or 64 bit system.
If true, the news will be welcomed by those who plan to install the new operating system on devices which do not have an optical drive, or by those who are tired of accumulating disks -- hoping they don’t end up scratched and unreadable.
Winfuture also reports that the USB option will be available for both Windows 10 Home and Windows 10 Professional.
