Windows 10 review

Revisiting Microsoft's make-or-break OS post-Anniversary Update

Our Verdict

The Anniversary Update is an impressive piece of work that ensures Windows 10 is on track to replace Windows 7. It's reliable, easy to use and keeps getting better – although there's still room for more significant improvements.


  • Start menu improvements
  • Action Center, Cortana are useful
  • Huge Edge browser upgrades
  • Windows Hello is simple and secure


  • OneDrive still patchy
  • Ink: a nice idea that needs work
  • The free upgrade is over
  • Changes improve but also cause issues

After more than 365 days, this make-or-break version of Microsoft's veteran Windows operating system is off to a strong start. And, the way in which new features and improvements keep arriving means that the Anniversary Update is a notable improvement over what shipped in July 2015.

We're a long way from Windows 8 now, and Microsoft seems to have got the hang of mixing the traditional keyboard-and-mouse driven desktop environment with touch features for the growing number of tablets and 2-in-1 PCs.

This release is a milestone for the 'Windows as a Service' process that Microsoft is using to develop Windows 10. Last year's November Update polished the release version of Windows 10, while this release continues that process, concentrating on the daily features you likely use the most, including some useful refinements to the Start screen and Action Center interface. But it also introduces some brand new features like the Ink Workspace.

The Edge browser has matured quickly and gets support for extensions, and the key UWP apps like Mail, Groove and Skype have also improved significantly. Cortana is gaining more features and Windows Hello is more reliable, as well as ready for apps and websites that support the new FIDO 2 specification that is bidding to replace passwords with biometrics. Improved browser security is a major plus.

Performance is improved from the already impressive speed of the release version of Windows 10 – booting your PC is a second or so faster on SSD-based systems, and battery life has improved on laptops (especially if you're using the Edge browser, but the new Battery Saver option that appears when you click or tap the battery icon also maximizes battery life).

Battery Saver

On the other hand, those uncertain about Windows 10 won't find solace in the fact that Anniversary Update only lets you roll back within 10 days to save on disk space, or the fact that, like any new release, there are problems (including some systems with SSDs freezing, and the well-documented problems with webcams that won't be fixed until another update arrives in September).

Latest news

It's been a long, winding road for Windows 10. Despite privacy concerns lurking around every corner, Microsoft managed to make it to 400 million installs. And, with the Anniversary Update behind us, we find ourselves wondering about the future of Windows 10.

On October 26, Microsoft hosted a press event in NYC where the company confirmed a Windows 10 Creators Update slated for spring 2017. This update features a swath of 3D creation, sharing and printing features, which include a brand-new version of Microsoft paint dubbed Paint 3D. The company also showed off Game Broadcasting baked into Windows 10 as well as a handful of Windows 10-compatible VR headsets from its partners. 

Last, but certainly not least, Microsoft updated its Surface lineup with a more powerful Surface Book, simply named Surface Book i7, complete with a 16-hour battery life and double the graphical capabilities. A Surface Studio all-in-one PC was also announced, geared towards artists and designers to take advantage of the Windows 10 Creators Update.

Windows is more than just an OS

Microsoft believes the future of Windows is as a platform for all. Like Android, the strength of Windows is in the thousands of companies that develop for it and use it in their products – on multiple devices.

That's why Windows 10 is no longer just an operating system for 32 and 64-bit PCs. It also runs on ARM chips as Windows 10 Mobile for smartphones (and, eventually, Microsoft promises, smaller tablets). That's thanks to the OneCore foundation of Windows.

Like Windows XP, Vista, 7 and 8 before it, Windows 10 is built on the Windows NT kernel, but much more of Windows is now shared between the different devices, and apps built for the Universal Windows Platform (UWP) will run not only on PCs, but on Windows 10 phones, Windows 10 for IoT devices, HoloLens headsets and Xbox One as well.

Note that we've published a distinct Windows 10 Mobile review here, for those of you who want the full lowdown on the OS from a smartphone standpoint.
