Clearing the air on rumours related to whether it would sell Windows 10 on USB drive, Microsoft has said users would be able to buy Windows 10 on a USB drive and install it directly without any need for a DVD drive.

"Windows 10 will be available on USB drives for purchase in retail channels shortly after launch. The suggested retail prices for Windows 10 in the US are the same as Windows 10," a Microsoft spokesperson told VentureBeat.

The USB drives will be available through retailers including the Microsoft Store itself, but the availability dates might vary depending on the retailers.

Meanwhile, Amazon has begun pre-orders for Windows 10 Pro (in Spanish and English) and Windows 10 Home USB flash drives. The suggested retail price noted for each version is $119.99; the shipment date is 30 August.
