Windows 10 vs Windows 8.1: which is best for you?

We rate Windows 10 and Windows 8.1 in a number of key categories for professional users

Windows 10 was released three years ago, and although many users initially resisted the change, it's most definitely here to stay. As always though, there are some die-hard fans of previous operating systems who have yet to make the jump.

Time is running out, however; Microsoft has ended mainstream support for the most recent major version of Windows 8.1, with extended support due to cut off in January 2023. If you haven't updated to Windows 10, it won't be too long before you're no longer able to do so safely.

Windows 10 vs Windows 8.1: Boot time

We've found no apparent difference in boot times between the two OS, at least not on the two computers we used for this test: a Lenovo ThinkPad X1 Carbon and a Microsoft Surface Pro. Both laptops booted to the login screen in eight seconds, under both Windows 8.1 and Windows 10; with only fractions of a second's difference between the boot times of the two OSes on either machine.

One feature that may potentially shave a few seconds off real-world boot times is Windows 10's facial recognition tool, which allows a user to be logged in the minute they sit in front of their PC. This feature, however, requires a special Intel RealSense 3D camera and will not work with an ordinary webcam. Along with fingerprint readers, these cameras are now relatively common in high-end notebooks, which gives Windows 10 a slight edge.

Winner

Windows 10, by a whisker, but only if you count the small potential time saving of facial recognition.

Windows 10 vs Windows 8.1: Interface

Without doubt, Windows 8's initial insistence on imposing the tiled Start screen on devices that didn't even have a touchscreen ruined any chance of the operating system ever getting widespread business adoption. Although the error was partially corrected by Windows 8.1, when desktop PC and laptop users could boot straight to the desktop and pretend the Start screen didn't exist, it was still needed for many core functions from launching apps to changing settings.

Windows 10 puts that right, albeit with an imperfect hybrid of the Windows 7 Start menu and Windows 8 Start screen. On desktops and laptops, the Start menu emerges from the bottom-left corner of the screen, with most-used programs listed down the left-hand side, along with a link to an A-Z listing of all installed apps, while the right-hand side shows the Live Tiles of the Windows 8 era. On tablets, it works very similarly to the way it did under Windows 8.1, with the Live Tiles expanding to dominate the entire screen.

We still think there's work to be done with the tiled section of the Start menu. With four different tile sizes and an awkward drag-and-drop system, it's too easy to end up with an untidy, gap-strewn mish-mash of tiles.

And once you've got more than a few live tiles activated, your screen can start to look like a Las Vegas casino, with a wall of rotating, scrolling squares each trying to catch your eye. Yet, it's undoubtedly an improvement on what went before for non-touchscreen devices.

Other notable new additions are the Cortana search bar in the bottom left of the Taskbar. We'll talk more about Cortana later, but the search bar lets you enter voice or typed searches for apps or files stored on your PC. You can click the My Stuff button in search results to perform more advanced searches of your own files, which certainly makes it easier to hunt down specific files than with Windows 8.1. However, we still find it easier to instigate advanced searches from within Files Explorer (called Windows Explorer in 8.1) and it's hugely disappointing that Outlook emails aren't included in searches.

Talking of Files Explorer, that's had a refresh too. Aside from a stark new set of icons, Explorer now has a Quick Access view which shows your most frequently opened folders at the top of the window, with a list of recently accessed files just below, making it easier to quickly pick up where you left off on files that are nested deep in folders.

You can still pin your favourite folders to the left-hand pane of Files Explorer, but this does create some duplication with the frequent folders pane just next to it, whilst the Libraries first introduced in Windows 7 are now almost hidden from view. The new Explorer is a modest improvement on Windows 8.1's, but again needs refinement.

One significant new interface element for businesses is virtual desktops. An idea brazenly lifted from the Linux world, Windows 10's virtual desktops let you keep different sets of apps open in different desktops. You might, for example, have one desktop dedicated to communications (with, say, Outlook, Slack and Skype running) and another for work on a particular project (Excel and a web browser). It allows you to compartmentalise your work, and avoid having desktops cluttered with several open windows, but it's frustrating that many apps designed to run full-screen on a touchscreen can only occupy a single desktop. 

Winner

Windows 10 corrects most of Windows 8's ills with the Start screen, whilst revamped file management and virtual desktops are potential productivity boosters. An outright victory for desktop and laptop users.

Windows 10 vs Windows 8.1: Stability

Even though it was the biggest overhaul of the OS since Windows 95, Windows 8 was remarkably stable and bug-free from the get-go. Indeed, we had it running on everyday work systems six months before launch.

Windows 10 has been, to put it charitably, a tad wobblier. Microsoft is regularly issuing updates for the software, but these updates often cause problems. It seems like every few months there are new reports of accidental file deletions, glitches, crashes and other assorted errors. General stability is certainly better than it was, but the fact that these errors persist is frustrating.

So far, we haven't seen any bugs that we'd consider enough to warrant downgrading to an earlier version of Windows, but it has to be said that reliability isn't Windows 10's strong suit - and it doesn't look like it ever will be. On the other hand, Windows 10 Enterprise users can cut out a lot of this headache - which we'll talk about more in a minute - meaning it's not quite so much of an issue.

Winner

Windows 8.1. Businesses can opt to skip many of the issues introduced by Windows 10's rolling updates, but the fact that they have to in the first place is hardly encouraging.

Windows 10 vs Windows 8.1: Enterprise features

Windows 8.1 actually did a fair amount of spadework for business users. Features such as Secure Boot, Windows To Go (giving you a bootable desktop from a USB stick), and Hyper-V virtualisation of guest OSes were features that were overshadowed by the focus on touchscreen devices.

All of those features remain in Windows 10, and there are others that could have a hugely significant impact on business rollouts. In-place upgrades have been made much smoother, meaning IT managers won't have to wipe and reimage as they may have done before. On our ThinkPad loaded with business-oriented desktop apps (Office 2013, Slack, Creative Suite amongst others), we performed an in-place upgrade to Windows 10 Pro in less than 40 minutes, with all documents, applications and settings perfectly retained.

Microsoft is also making it much easier for IT managers to bring off-the-shelf hardware into businesses, with new runtime configuration tools that can implement VPN settings, e-mail profiles, app installations and security policies without wiping the hardware and starting afresh.

Microsoft has also been commendably wary of forcing businesses to install the same rolling updates to Windows 10 that are now mandatory for consumers, who can no longer opt out of Windows Updates. Enterprise users can opt for a Long Term Servicing Branch of the OS another idea pinched from Linux which allows them to install a stable version of Windows 10 on mission-critical machines, which will only receive essential security updates and not the new features that will be periodically rolled out to regular Windows 10 users. Windows 10 Pro users, meanwhile, can defer updates, giving new features a few months to bed down on consumer systems before they're applied to a business machine.    

Winner

Windows 10. Windows 8 didn't get the credit it deserved for enterprise features, but Windows 10 expands them even further and makes rollouts less of a headache for IT departments.

Windows 10 vs Windows 8.1: Security

Controversial though it was, because of the way it shut out some Linux distros, Windows 8's Secure Boot eliminated the threat of some of the most harmful types of malware. It was also the first version of Windows to ship with built-in antivirus protection, even if Windows Defender does routinely perform poorly in Dennis Technology Labs' independent tests.

With Windows 10, Microsoft is turning the screw even tighter with Secure Boot, giving PC manufacturers the option to prevent users disabling the feature. That might upset consumers who want to dual-boot OSes, but the vast majority of business machines will only ever boot into the OS the device is shipped with, and this prevents almost any chance of malicious rootkits or other low-level malware infecting the boot process.

The addition of face and iris recognition to the list of user authentication options already within Windows 8 potentially adds extra convenience for both users and IT departments alike (unlike passwords or smartcards, nobody forgets their face). However, both require specialised hardware, and neither is common enough to be a universal standard yet.

Winner

Windows 10 edges ahead of its predecessor, but the new authentication options still haven't fully caught on.

Windows 10 vs Windows 8.1: Mobility

Windows 8.1 was already a pretty decent tablet OS, hampered largely by a poor selection of high-quality apps in the Windows Store. At this stage, it's hard to tell if Microsoft's new Windows 10 plan for Universal Apps apps that run across PC, tablet and eventually phones will bear fruit, but Windows 10 is already a better tablet OS than its predecessor. 

One reason for this is Continuum, which automatically adapts the Windows 10 interface to suit the mode it's being used in on hybrid devices. Detach a device such as the Surface from its keyboard, and Windows 10 prompts you to enter Tablet Mode, where the Start menu spans the full screen, the Taskbar disappears, apps run in full screen instead of windows, and you effectively get no access to the desktop.

Reattach the keyboard, and the Start menu shrinks back into its corner, the Taskbar springs back, and apps can be run in whatever size of window you choose, even touchscreen-focussed apps from the Windows Store. It's a brilliant feature, possibly the best Windows 10 has to offer, and a real boon for hybrid devices, making the shifting between modes feel much smoother and making them feel like two distinct devices. Our only gripe is that Windows 10 doesn't always recognise a change of mode if you've, say, detached a keyboard while the device was switched off. However, you can easily activate and deactivate Tablet Mode manually via the new Action Center.

Windows 10 also introduces a Battery Saver mode, dimming the screen and cutting down on needless notifications to preserve battery life. It automatically kicks in when the battery dips below 20%, but you can apply the mode manually, too. It's not going to add hours to your laptop's/tablet's run time, but every little helps.

Winner

An emphatic victory for Windows 10, which finally makes sense of hybrid devices, and adds limited battery saving benefits.

Overall Verdict

It's not perfect and it's now a permanent work in progress, but Windows 10 shows that Microsoft can pull off what many thought impossible: an operating system that sits comfortably on desktops, laptops and tablets.

Windows 8 and 8.1 now feel like the prototypes Microsoft had to work through to find an operating system that worked on all three types of computer, and in many ways it's a shame that process had to be done in public, but Microsoft's not only heard the howls of complaint about Windows 8, but acted upon them.

If businesses rightly shied away from Windows 8, we can see few reasons to shun its successor. The Start menu is less jarring and intimidating than its Start screen predecessor, the migration path is smoother and there are numerous security and productivity benefits. Despite the kinks, we would wholeheartedly recommend upgrading both existing equipment and pre-installing Windows 10 on new machines.
