If a latest report is to be believed, the hype and excitement over the launch of Microsoft's soon-to-be launched Windows 10 operating system will not help to improve the sagging sales of personal computers. In fact, the report says that the global sales of PCs will drop by further 6.2 percent in 2015, notwithstanding the fact that the new OS will correct the errors in Windows 8 as well as Windows 8.1.

According to a recent report in IB Times, the projected slide in PC sales this year reflects a worrying performance descent by the industry from last year, when the sales of PCs dropped by 2.2 percent. The forecasts for 2016 released by the research firm International Data Corp. (IDC) are also depressing since the most recent data envisages another decline. The firm estimates that sales growth will elude PC vendors even 12 months after the worldwide circulation for Windows 10 operating system.

While Microsoft is expected to roll out Windows 10 in July, the IDC report stated that the estimated migration from older Windows versions to Windows 10 is expected to be across-the-board as well as quick, but the PC makers will not be rewarded monitarily. Meanwhile, the Redmond-based tech giant has already announced that its upcoming OS will be absolutely free for users running Windows 7, 8 and 8.1 on their machines.

While this offer has been welcomed by millions of consumers across the globe, it will certainly not encourage hardware upgrades, because the software upgrade would be satisfying for the moment. Citing the IDC report, ZDNet stated, "IDC says the free Windows 10 upgrade will reduce the need for consumers to rush out to buy a new computer."

Meanwhile, the most recent report released by IDC also emphasizes the possibility of continued deterioration not only of conventional computing devices, such as desktops and laptops, but also of tablet computers. The growing interest of consumers on hybrid as well as supersized smartphones will only add to the dwindling sales of PCs and tablets, IDC said.

Continuum on Phone, a feature on Windows 10, is considered to be another likely culprit. This feature allows the users to port a phone screen into a bigger monitor enabling them to perform all usual computing tasks using their mobile device.
