Windows 10 is only a free upgrade from Windows 7 or 8.1 until the end of this month1. If you've hesitated so far, you might be a bit unsure as to whether you should switch a system you're satisfied with for a potentially less satisfactory one. But, if you want a free upgrade, you haven't got long left, so you need to decide whether to take it up very soon.

Earlier this year, I installed it on one PC, partly to test Traktor out on a clean install of Windows 10, and partly to claim the free upgrade on that PC. That went OK. And, as I'm claiming free upgrades on other PCs that I'm caring for, you might think that, at least, I don't loathe the new version enough to not switch. From what I've seen, that's true, though it has a few residual problems, even almost a year after release.

What I do know reasonably well is the installation process as I've been through that a few times now, so I'll focus on how that compares with previous versions.

Before you start, if you have an existing installation, it's worth checking in the "Get Windows 10" app whether you have any compatibility issues. As far as I can tell, there's no separate checker you can run. If, like me, you disabled that annoying application, you'll want to re-enable it and see if there are any potential issues from any applications or hardware you have.

Clean installation

Clean installation is a lot simpler than when Windows 10 was first launched, if you're claiming a free upgrade. Since the Threshold release last year, you can simply enter your existing Windows 7/8 product key, and that will be activated. No need to do a upgrade over an existing installation solely to claim a digital entitlement, and then reinstall.

The installation process is very similar to that of Windows 7 and 8, and simple enough to navigate. Boot up the installer, select language options, choose where you want to install the operating system, wait a few minutes and you should soon have a working Windows install.


In the past, even as recently as Windows 7, installing hardware was a mess in that you'd often have to trawl badly designed hardware manufacturer websites for several drivers you'd need to make everything work. Often, you'd be prompted to check online for drivers, only for Windows to unhelpfully say "sorry, go and find them yourself" (polite paraphrasing mine).

This seems particularly backwards compared to modern Linux installs where, at least in my limited experience, most hardware works without much user intervention. In this respect, Windows 10 has caught up2. For the PCs I've tried Windows 10 on, almost all the hardware has been correctly detected and the drivers installed.

Even on a PC near a decade old, long since abandoned by the manufacturer, it was a particularly pleasant surprise to find that almost everything had been correctly installed. The main exception I found was a Native Instruments audio interface, but I realise that's not common hardware.


One of the major drawbacks of Windows past is the update system. A fresh install of Windows 7 now requires in excess of two hundred updates, which greatly extends the time to complete the install. You'll endure reboot on reboot, until it's done. If it's done. Unfortunately, it's also possible to run into failures while installing such an inordinate number of updates; trying to install as many updates in one go to minimise rebooting sees some phenomenal memory usage.

That wasn't helped by there only being a single service pack for Windows 7, released several years ago, so you still need all updates released since then.

(While you can slipstream updates into Windows installers, that's not going to be something that many users bother with.)

Here, Windows 10 seems a big improvement. Installers available from Microsoft's site are regularly updated: the one I've used recently is from April of this year. This means that there shouldn't be many more updates required for your newly installed system.

On top of that, they've made the updates cumulative, so you only need the latest to get all fixes. Furthermore, they're all rolled into a single update, which means there's very little that a new system needs.

The downside of this, of course, is that you can't pick and choose what applies. The past has seen cases where rogue Windows updates can critically break systems: recently, in my experience. With Windows 10, all you can do is not apply any subsequent updates whatsoever until your issue with the updates gets resolved. Relying on the stability of a house of cards doesn't seem that wise.

More positively, there is an upside of the cumulative update system. Previously — and I've encountered this firsthand for XP and Windows 7 — as a particular Windows version grows older, Windows Update becomes far creakier. In recent months, Windows Update has taken the best part of an hour to check for updates on relatively modern Core i5 machines, and hours on my ancient Core2Duo PC. If this new method of rolling out updates avoids this, it will prevent much user frustration as the operating system gets older, particularly if, as Microsoft claim, this is the "last version" of Windows.

Upgrade install

I'm not a huge fan of upgrade installs with Windows. Usually, if a full installation is warranted, enough time has passed that it's often worthwhile to do a clean install. In one case I dealt with, I felt it was worth a try first as reinstalling everything would be a lot of work3. If all else failed, a clean install was still an available alternative.

In fact, the upgrade install went without a problem. Downloading the installer for reuse is a smart idea if you have several PCs to upgrade. You can download a USB creator or ISO from Microsoft's site, and run setup.exe within your current install to upgrade.

The whole process didn't take too long either and didn't seem to cause any problems following it. Microsoft do blatantly ignore your existing choice of browser and select Edge as the default for you though… thanks for that.

And after installation?

Despite it being out almost a year, I'm only really now starting to use Windows 10 on a regular basis. Where possible, I'd rather hold off if I have systems that are working well and let others find and report bugs.

Even from the outset of installation, one noticeable difference to previous versions of Windows is the number of privacy options there are. Microsoft are intent on collecting much more data than in previous versions of Windows. What you should be reading is this page on Microsoft's site that details telemetry to tell you exactly what can be disabled.

Other problems

Several other things I don't like have emerged over the few hours I've used Windows 10.

  1. Windows 10 sees the return of the Start menu on desktops, which was one of the big pain points of Windows 8. What still remains is a slightly uneasy mix of normal applications, and universal ones. This particularly affects settings. For example, there are two separate applications you can use to remove software: that as seen in the traditional Control Panel and another that's a universal looking app. That just feels indecisive. Likewise, prompts are a mixture of old and new. It's not enough to be too distracting, but does feel unpolished.

  2. Speaking of the Start menu, there are lots of things that clutter it by default. There are more bundled apps (for instance, Twitter, Skype) too which some may find useful, but I'd prefer to not have them installed by default. OneDrive integration might be desirable for some people, but not for me, so it's disabled; the simplest way is to go to Group Policy and disable it there.

  3. The default theme is ridiculously bright. When I used it earlier this year, I found it felt tiring to work with over long periods. The Anniversary Update to be released soon finally promises to reintroduce an Aero-like theme, which should address that complaint.

  4. Another problem is that using BitLocker still requires a premium version of Windows. I have that, so it doesn't affect me, but I don't understand why Microsoft count what is nowadays a fundamental security feature as optional. Lots of consumer laptops will only have the Home version of Windows which doesn't feature BitLocker.

    Since Windows 8.1, there's another encryption option called "Device Encryption". It's also really difficult to find useful documentation about this option on Microsoft's site. I did find a couple of more informative links on Microsoft's site: "What's New in BitLocker" and the Windows 10 Security Guide. The requirements are declared in the Windows 10 Specifications. Spoiler alert:

    Device encryption requires a PC with InstantGo and TPM 2.0.

    But lots of budget hardware skips on the Trusted Platform Module. And, I might be mistaken, that still doesn't cover securing removable drives for non-Pro/Enterprise users.

  5. The frequent notification to "install a language to enable typing features" gets tiring fast. As far as I can tell, the only way to disable it is bowing to its demands. If you just ignore it, it decides to reappear at regular intervals. That's a sloppy bit of user interface design.

  6. The issue where you need to use the systempropertiesperformance fix to disable animations and other visual enhancements for non-admin users still remains. Otherwise, changes made disappear once you log out.

But Windows 10 is worth a try

That's a long list of complaints, but actually I'm more positive about Windows 10 than that might suggest. My near-decade old PC with an SSD boots Windows 10 in around twenty seconds from power on, which feels brisk. And there's nothing I've seen yet that seems particularly detrimental in terms of major problems or compatibility issues. Lack of BitLocker for home users aside, there's not much in the way of major issues.

If you've been hesitating, it's worth taking a look. Especially given that my understanding from reading elsewhere is that the digital entitlement may well work as follows: once you've claimed the Windows 10 free upgrade entitlement for a PC before the deadline, even if you revert to your previous version of Windows, the upgrade remains valid even after the deadline.

  1. That month is July 2016. And it holds unless Microsoft decide that they need a greater user uptake than they have now, and announce a deadline extension. 

  2. I never used Windows 8 enough to know if the improvements in driver detection were there or not. 

  3. There was a substantial customised game installation which would have taken a long time to install the addons all over again. The previous upgrade strategy from XP to 7 was to copy everything over, then reinstall whichever extras for that game required it.
