Earlier this week, the sales of Microsoft Lumia 950 XL were halted by several retailers citing problems with the device. Microsoft has stated that the reason why the Lumia 950 XL remained unavailable with many retailers was that its stocks had depleted.

The sales of Lumia 950 XL have now resumed. On the official Windows Blog, the Redmond giant has announced that the initial demand for Lumia 950 and Lumia 950 XL have exceeded their supply. Both the smartphones have met great start and the company is actively trying to replenish the stocks with different retailers. The retailers that haven’t yet resumed the sales of the Lumia 950 XL are likely to begin by the end of January.

The new operating system, Windows 10, has also met with good reception and its user base is consistently expanding. The Windows 10 operating system is active on 200 million devices. It also accounts Xbox One gaming consoles that are now powered with Windows 10 OS.

During the holiday season, the Windows Store accounted twofold increase in sales from PC and tablet users. In December 2015, 60 percent of customers who made purchases on the Windows Store were new to it. In the December month, in comparison to Windows 8, the newly released Windows 10 OS produced 4.5 times more revenue per device.

Microsoft is yet to begin the official release of Windows 10 Mobile OS for Windows Phone 8.1 users. The Lumia 950, Lumia 950 XL and Lumia 550 are the only smartphones that offer out-of-the-box Windows 10 Mobile experience.

Only users have registered with the Windows Insider program are able to install the test builds of Windows 10 Mobile on eligible devices. Rumors are rife that official Windows 10 Mobile OTA (over-the-air) update will be available to the users as early as Jan. 12.
