Windows 10 Technical Preview

Microsoft Windows 10 review - CNET

Windows 10 is the Goldilocks version of Microsoft's venerable PC operating system -- a "just right" compromise between the familiar dependability of Windows 7, and the forward-looking touchscreen vision of Windows 8.

This new Windows, available as a free upgrade for existing Windows 7 and Windows 8 noncorporate users, is built from the ground up to pursue Microsoft's vision of a unified OS that spans all devices without alienating any one platform. It's an attempt to safeguard Microsoft's crumbling software hegemony, assailed on all sides by Google and Apple. And it's a vision of the future as Microsoft sees it, where a single user experience spans every piece of technology we touch. Welcome to Windows as a service.

Yes, this new OS is chock-full of fresh features. To name just a few: a lean, fast Internet Explorer replacement called Edge; Microsoft's Siri-like voice-controlled virtual assistant, Cortana; and the ability to stream real-time games to your desktop from an Xbox One in another room. (And in case you're wondering: there is no "Windows 9" -- Microsoft skipped it, going straight from 8 to 10.)

We’re getting close: Microsoft has been issuing new Windows 10 Insider Preview builds on a regular basis, ahead of the official release July 29th. Want to try it out? There are 64-bit and 32-bit versions available for US and UK English, Chinese, and Brazilian Portuguese, among other languages. Follow these instructions to download and install the Windows 10 Insider Preview.

Be prepared

However, if your Windows 10 upgrade was completed less than 31 days ago, you won't be offered the November update until the full 31-day period has passed. (Microsoft says this is a precaution to ensure that you can roll back to your previous Windows version if you choose to do so.)

How long does a Windows 10 upgrade take?

That depends on the resources available to your device, The more raw CPU and (especially) disk storage speed you have available, the faster the upgrade will complete. On most systems, the process should require 1-2 hours and runs completely unattended.

Note that the November update is a full upgrade and will take about the same amount of time as an upgrade from an earlier version of Windows.

Is it possible to upgrade Windows 7 or 8.1 to Windows 10 using Windows Update?

Since the initial release date, Microsoft has delivered Windows 10 online via Windows Update to people who placed an online reservation. On systems that are eligible for the free Windows 10 upgrade where automatic updating is enabled, the Windows 10 installer files download automatically in the background.

Virtual desktops help you spread your apps across several workspaces.

Virtual desktops are far from a new development, and they've been available in past versions of Windows thanks to third-party apps. But it's nice to see Microsoft catching up here. The feature could still use some work: desktops are numbered, but if you create a lot of them it can be hard to keep track of where everything is. The "traditional" Win32 apps you might download and install from a website are happy to open a new instance on any desktop, while clicking the shortcut on an app from the Windows store will yank you back to whatever desktop you used it on last.

You can move apps across virtual desktops -- just drag them, or right-click to shunt them over -- but there's no way to reorder the virtual desktops themselves, which would be really useful for staying organized. I'd also like to be able to set a different wallpaper for every virtual desktop -- I can do both of those things in Apple's OSX operating system, and have always found it really handy.

You can upgrade your existing Windows 7 or Windows 8/8.1 installation to the Windows 10 Insider Preview. I would advise you to do a clean installation of the Insider Preview, however, on a separate partition or hard drive, in case something messes up. Eventually, each Insider Preview license expires, but not before another Preview build is released. Other potential caveats/pitfalls can be found on the Windows 10 Insider Preview FAQ.

Yes, as long as the virtualization software is compatible. I have had no problems running test installations in several Hyper-V virtual machines on Windows 8.1 and Windows 10.

How do I install the November Update if Windows 10 is running on a VHD using native boot?

A quick explainer for those wondering what that question even means. Native boot is a feature that was introduced with Windows 7 and is documented in this Knowledge Base article. With native boot, you can install a business edition of Windows 7 or later in a Virtual Hard Disk (VHD) file. The setup instructions in this article appear to be valid with the Windows 10 Technical Preview, in my testing.

The advantage of installing on a VHD is that you don't have to mess with disk partitions. Windows mounts the VHD file when it starts and treats it as though it were a physical disk. Your main OS remains on the disk itself, allowing you to easily set up a dual-boot system to see how Windows 10 will run on your hardware without creating a mess.

Although it's not well documented, this type of installation has a significant limitation. As this TechNet article notes, "If you boot from a VHD, you cannot upgrade the Windows version in the VHD to a newer version."

The only alternative is cumbersome. The short version is this:
