What is Windows <strong>10</strong>?<br />

When you think of Windows, you probably think first of conventional desktop PCs and laptops. The<br />

Windows <strong>10</strong> release encompasses a much broader range of devices, as Figure 1-1, taken from a Microsoft<br />

presentation, makes clear.<br />

FIGURE 1-1 The Windows <strong>10</strong> family spans a wide range of devices, from phones to game consoles and the new<br />

HoloLens headset, with PCs in the middle.<br />

Although all these devices share a great deal of common code, it’s not the case that the same code<br />

will run on each device. The version of Windows <strong>10</strong> Enterprise for a 64-bit desktop PC, for example, is<br />

very different from Windows <strong>10</strong> Mobile or the Windows <strong>10</strong>–based operating system that powers the<br />

Xbox One game console.<br />

But that common code has a big payoff when it comes to app development. Apps that are built on<br />

the Windows <strong>10</strong> universal app platform can run on all Windows <strong>10</strong> device families, delivered through a<br />

common Windows Store. They are also easier to manage and more secure than conventional Windows<br />

desktop applications, which run only on PCs.<br />

A new approach to updates and upgrades<br />

As I mentioned, the most revolutionary change in Windows <strong>10</strong> is the concept of continuous improvement.<br />

New features are delivered through Windows Update, rather than being set aside for the next<br />

major release. In a major change of longstanding best practices, Microsoft now recommends that<br />

enterprise customers enable Windows Update for the majority of users, although the option to use<br />

Windows Server Update Services (WSUS) is still available for some configurations.<br />

In the new “Windows as a Service” model, Microsoft plans to deliver significant upgrades, with new<br />

features, two or three times per year. That’s a dramatically faster pace than the traditional Windows<br />

release scheme, in which new features were reserved for new versions released with great fanfare every<br />

three years or so.<br />

To help IT pros adapt to this new, faster pace of change, Microsoft has built a new servicing model<br />

for Windows <strong>10</strong>. Security updates continue to arrive on the second Tuesday of each month via Windows<br />
