Cortana on Lenovo

While HP and Dell have already started taking orders for their first PCs with Windows 10 pre-installed, one of their biggest rivals, Lenovo, won't begin that process until July 29, the official launch date for Microsoft's latest OS.

Windows Central asked Lenovo when they will start taking orders for their Windows 10 PCs and got this response from a spokesperson:

"Yes we will take orders on the 29th and ship by mid August."

HP and Dell have not only started the pre-order process for their first Windows 10 PCs, but HP will begin shipments on July 28, with next-day deliveries arriving on Windows 10's launch date on July 29. Dell will begin their shipments on that date, with the first PCs arriving to customers the next day on July 30.

Lenovo has already posted a "Starting to use Windows 10" guide online to help its customers use Microsoft's new OS. It has also revealed plans to extend the features of Windows 10's Cortana digital assistant with REACHit, which will allow users to search for their photos, videos, documents and music across devices and cloud storage services.

Finally, we can also note that certain Lenovo's already running Windows 10 through the Insider program are now receiving Windows 10-specific drivers from the company, ensuring a smooth transition to the finalized OS.
