You can spend thousands of dollars on components when building a PC, but it won’t boot without an operating system (OS). Linux is a viable option, but most people prefer Windows because it runs all of their favorite software, including the latest games. Fortunately, you can get Windows 10 for free or cheap, if you know where to look.

Getting hold of the Windows installer is as easy as visiting support.microsoft.com. Whether you've paid for Windows 10 already or not, Microsoft lets anyone download a Windows 10 ISO file and burn it to a DVD, or create installation media on a USB drive for free. Once that's done, you can boot from your installation media and load Windows 10 onto your PC. During the installation process, Microsoft asks for an activation key. You can skip it, but eventually, Windows will start alerting you that your install isn't activated.

There are many ways to get a Windows 10 activation / product key, and they range in price from completely free to $399 (£339, $340 AU), depending on which flavor of Windows 10 you want. You can of course buy a key from Microsoft online, but there are other websites selling Windows 10 keys for less. There’s also the option of downloading Windows 10 without a key and never activating the OS. But what, if anything, are you missing out if you don’t activate Windows 10? And does your carefully crafted rig face any risks?

Below we outline the top ways you can get Windows 10 -- from the cheapest to most expensive -- and the downsides of each option.

Use an Old Key: Free

Nothing’s cheaper than free. If you’re looking for Windows 10 Home, or even Windows 10 Pro, it’s possible to get the OS onto your PC without paying a penny. If you already have a software/product key for Windows 7, 8 or 8.1, you can install Windows 10 and use the key from one of those older OSes to activate it. But note that a key can only be used on one PC at a time, so if you use that key for a new PC build, any other PC running that key is out of luck.

Downsides of Using an Old Key

When using an older Windows key to activate Windows 10, you may run into complications if Microsoft isn't sure whether you're eligible to update or not. In that case, you’d have to call a number and go through a process of entering your key and getting a code. But that seems to be happening less in recent months and years.

Don't Activate Windows: Free

If you don't have a valid key, you can still use Windows 10 on your PC even if you don’t activate the OS. I have colleagues who have used non-activated versions of Windows for years without Microsoft ever shutting it down. In this way, you can have Windows 10 Home or Pro running on your PC nearly flawlessly. Nearly...

Downsides of Not Activating Windows

“If the user [installs Windows 10] before activating Windows, they will see an ‘Activate Windows’ watermark on their desktop, as well an experience a limit on Windows 10 personalization options,” Microsoft told Tom’s Hardware in a statement.

Microsoft brands PCs running an unactivated version of Windows 10 with a watermark in the bottom-right corner of the screen. A Microsoft spokesperson told me that activating Windows 10 ensures you have a legitimate copy of Windows 10, and the watermark is an attempt to alert consumers that their version could be false. However, if you downloaded your ISO directly from Microsoft, there's no way your copy can be a fake.

Watermark seen on non-activated version of Windows 10

If you don’t activate Windows 10, you won’t be able to change Personalization options in the Settings menu. That means you can't choose personal desktop wallpapers, slideshow backgrounds, Start, taskbar, Action Center or title bar colors, light or dark color schemes, font choices or lock screen options.

The lack of custom aesthetics can be a downer, especially if you like to liven things up by changing colors and images. However, we checked, and you can still change your wallpaper if you right-click an image from the web or a personal photo and set it as your wallpaper. And if you have a wallpaper tied to your Microsoft account, it will appear if you sign into Windows with that account.

You can't access personalization options if you don't activate Windows 10. 

Unsurprisingly, Microsoft won't offer you any Windows 10 technical support if you don’t activate the OS. If you call or chat with their techs, they'll start off by asking you for your key, and you’ll have no response.

Use the Microsoft Student Discount: Free

Microsoft offers students attending certain universities and high schools the ability to activate Windows 10 Education for free. Teachers can get Windows 10 Education for $14.99. You can see if your school is eligible and download your free key here. The key is yours even after you graduate.

But is Windows 10 Education any different from Windows 10 Home? It’s actually better. Windows 10 Education is the same as Windows 10 Enterprise, which Microsoft calls the most robust version of Windows 10. The OS has features targeting security, device control and management and deployment that Windows 10 Home lacks. Unlike Windows 10 Home, Windows 10 Education has client and host remote desktop and remote app i(nstead of client only), Hyper-V (Microsoft’s hypervisor) and extra apps, like AppLocker and BitLocker. Although, it’s likely you won’t ever use any of those bonus features.

If you’re not currently a student but happen to have a .edu email, we don’t recommend scamming the system. In addition to ethical concerns, if you get caught, Microsoft can make you pay up anyway. “False representations of eligibility voids this offer, and Microsoft reserves the right to collect the full price of product(s) ordered,” Microsoft’s policy states.

Downsides of Using the Microsoft Student Discount

If your school is eligible for the discount, there isn’t really a downside to this method of procuring Windows 10. Not all colleges / high schools have it, and you may need to make a special user account to download it. But if you can score Windows 10 Education for free, we don’t see any reason not to.

Buy a Cheap Windows 10 Key From a Third-Party Seller: Around $30 (£24, $44 AU)

If you can’t stand living with the scarlet letter of an eternal watermark or want the comfort of knowing Microsoft won’t disown your PC’s OS should you call for help, you’ll have to buy a Windows 10 key. And while some turn to Microsoft for this purchase, there are third-party websites selling keys for much cheaper than Microsoft. For example, at the time of writing, Kinguin sells Windows 10 Home for $21.02, PCDestination has it for $44.99, Amazon charges $99.95, Newegg's' pushing it for $99.99 and even Walmart has it for $116.25.

Now, let's address the elephant in the room. While we can't vouch for all of them, websites selling lower-priced Windows keys are likely selling legitimate codes. One popular site, Kinguin, has 37 merchants worldwide selling Windows keys. Mark Jordan, Kinguin’s VP of communications, told me that their merchants acquire the codes from wholesalers who have surplus copies of Windows they don't need.

"It's not a gray market. It would be like buying Adidas or Puma or Nike from a discounter, from TJ Maxx," Jordan said. "There are no legal issues with buying it from us. It's just another marketplace."

According to Jordan, Kinguin's merchants have sold “several hundred thousand” keys and are not one-time sellers posting listings for codes they don’t want. As part of its fraud protection, a Kinguin employee randomly buys a key “every now and then” to make sure they’re legitimate, he said. Jordan added that it’s rare for a customer to get a key that’s been resold, but if they did, customer support would help them get a new one for free.

“If there's ever a problem with a key being already activated or something like that, our customer support team helps you get a new key… And that merchant would be in deep trouble, so they are very careful with it,” Jordan said.

You'll have to enter a key to activate Windows, but you won’t have a problem doing that if you bought your key from a place like Kinguin (or Amazon, Newegg, etc.). In fact, Microsoft still offers 24/7 technical support online and via phone even if you got your Windows 10 key from somewhere other than Microsoft.

If you do opt to get your key for less, make sure it’s from a legitimate site. A hint will be if that key is too cheap -- i.e. free or close to free. And, as with anything else, if you haven't heard of a seller, check their ratings or go elsewhere.

No matter where you get your product key, you shouldn't download Windows 10 from anyone besides Microsoft. As noted on Microsoft’s website: “When buying Microsoft software as a digital download, we recommend that you avoid auction sites and peer-to-peer (P2P) file sharing sites. At the moment there are a limited number of sites where you can legally purchase digital downloads of Microsoft software.”

“Genuine Windows is published by Microsoft, properly licensed and supported by Microsoft or a trusted partner. Non-genuine software results in a higher risk of malware, fraud, public exposure of your personal information and a higher risk for poor performance or feature malfunctions,” Microsoft added in a statement to Tom's Hardware.

Downsides of Cheap Keys

These non-Microsoft websites have varying return policies for software key purchases. While Kinguin seems to have an open return policy, PCDestination returns can only happen if the key can’t be activated and have to be requested within 60 days.

Meanwhile, Amazon and Newegg both have no-refund policies for software keys. Amazon claims all keys sold on its site are genuine, and any gripes you have with your key must be handled by the individual vendors. If a key you bought from Newegg doesn’t work, you'll have to contact Newegg’s product support team to get a new key.

Still, most, if not all, sites seem willing to accommodate you should you get a key that’s already been used or doesn’t work. Again, just make sure you’re buying your key from a legitimate source. For that reason we don’t recommend buying Windows 10 keys from individual sellers (or illegally).

This final downside is only applicable if you want to equip your PC with Windows 10 Pro for Workstations. While I was able to find Windows 10 Home on a number of genuine key-selling websites and Windows 10 Pro on some (although fewer) websites, I couldn’t find a place to downlaod a key for Windows 10 Pro for Workstations anywhere besides Microsoft (Amazon sells it to ship for $279.49.). The most advanced and pricey ($309) member of the Windows 10 clan, Windows 10 Pro for Workstations offers “support for the next generation of PC hardware, up to four CPUs and 6TB of memory,” according to Microsoft’s website. But it’s unlikely you’ll need the juggernaut of Windows 10 for your personal machine.

Buy a Windows Key From Microsoft: $139+ (£120, $225 AU)

Want a version of Windows 10 where you can enjoy dynamic slideshows on your home screen and vibrant red, green, pink, or purple taskbars? Do you enjoy the thrills of a watermark-free screen and the comfort of knowing you can call Microsoft support if you have any problems? Then you need a key, which, as discussed, you can get from various retailers. But if you want to avoid any chance of getting an unusable key or want the guaranteed ability to get a full refund even if there’s no problem with the key, your best bet is buying from Microsoft.

In addition to selling keys for Windows 10 Home and Pro, Microsoft is the only place you can get a key for Windows 10 Pro for Workstations. Additionally, Microsoft offers the Assure Software Support Plan for an extra $99 (£95/ AU$120). This plan is valid for a year after activating Windows 10. It’s applicable for up to five devices and entitles you to online and phone support and one-on-one in-store training. One caveat: Microsoft says the plan is “for purchase and activation only in the region in which it was acquired.”

Downsides of Buying from Microsoft

Microsoft charges the most for Windows 10 keys. Windows 10 Home goes for $139 (£119.99 / AU$225), while Pro is $199.99 (£219.99 /AU$339). Despite these high prices, you’re still getting the same OS as if you bought it from somewhere cheaper, and it’s still only usable for one PC.

Additionally, the premium price doesn’t entitle you to any support perks. Microsoft’s 24/7 basic phone and online support is available to anyone with a Windows 10 key, even those who didn't get it from Microsoft. After already investing time and money PC building, it can be difficult to convince yourself to spend over $100 for an OS when you can get it with the same specs and support for cheaper.

What's the Best Way to Get Windows 10? 

If you have an old Windows key you can carry over from a previous build, that's your best option. 

If you don't have a key on hand, you need to decide whether you're comfortable using an unactivated version of Windows 10, which limits your customization options, has an ugly watermark and leaves you ineligible for Microsoft support. Many would argue that downloading Windows without paying for or already owning a product key is ethically wrong. That said, Microsoft has made this process easier over various Windows iterations and lessened the limitations and nagging that happens when you don't activate. The company isn't trying to close this loophole, probably because it’s more interested in driving user numbers. I've even seen well-known vendors and Microsoft partners do press presentations with watermarks on their desktop.

If you must buy a Windows 10 key, it's hard to argue against purchasing one from a low-cost seller such as Kinguin or PCDestination. Microsoft's price is astronomically high and doesn't offer any significant benefits. You can save $100 or more by buying a key from one of these third-party sites, which is money you can spend on a better graphics card, a roomier SSD, or a few AAA games for your new PC.

    I bought a key on ebay and it turned out to be a VL key (volume). Which works but shouldn't be sold. I contacted the seller and he refunded me. To check if your key is retail/oem/volume type "slmgr -dli" on the command prompt.

    Very good breakdown of the ways to activate Windows 10. Most people don't even realize you can still use a windows 7 key to activate, only after you get into windows, and not during the setup process. I believe this will probably stop working Jan 1, 2020, when Microsoft stops support for windows 7.

    One thing that I was hoping for some explanation on key activations, I have seen how some Youtuber's have tied their windows 10 keys to their Microsoft account. Then they only need a handfull of keys, like one for each motherboard vendor, and during setup, then sign into their Microsoft account, and select the key that corresponds to the motherboard their are reviewing. So they can move the keys around, and as long as it was the same brand of motherboard it would activate for that computer, and no longer be active on the old system. Any thoughts on how this works? Any limitations on how many moves, is this method valid for years so you would never have to buy another key if you stayed with one particular favorite motherboard vendor?

    Newegg often has Microsoft packaged Win10 for $89.
    On the forums, we see MANY tales of woe concerning aftermarket, 3rd-party, or otherwise dicey Windows keys. In my opinion, unless you know exactly what you are doing, the time, effort, and hassle you might save yourself by using a retail source is worth the $50 you might save by going for an aftermarket key, even if guaranteed. Of course, using an old version's key essentially amounts to a free upgrade, which once upon a time was often provided by software vendors, so if you can use that method, great.

    Any attempt to connect to www.kinguin.net, using Firefox, Chrome, or Edge, returns an error indicating it cannot establish a secure connection. Sorry, not getting my business.

    Couldn't agree more. Simply put, this is a bad idea.

    Thanks for this article. I've been struggling with the idea of buying another copy of Windows 10 for my media machine. It's a PC built from old parts and is currently running Linux.

    My main problem is this: Linux can't stream HBO, FOX Sports, Disney XD and other streaming services, so as a media machine it's a big problem...

    I looked into the $30 windows option but it sketched me out. Has anyone had a good experience with this?

    Cheap 3rd party Keys like the ones sold on Ebay are STOLEN. While they might activate today there is no guarantee they will activate a month from now or whenever you decide to reinstall windows from scratch.

    This article is causing multiple conniptions among the Moderation team. There are very good reasons why, although tolerated from a couple of well-known sources like Kinguin, none of us ever encourage people to obtain keys this way. It isn't illegal, so we don't sanction for it, but like I said, the tales of woe are too numerous to go unnoticed. Microsoft hasn't loosed its lawyers on Kinguin, so it is apparently not a matter of legality, but there are a number of threads that basically boil down to "I told you so" and/or "You're on your own" when it comes to aftermarket keys.
    At least the article makes no mention of "activators," which in most cases do represent outright piracy, not to mention the viruses and malware with which they are often laden. Discussions of those are not allowed and are deleted, and sometimes offenders knuckles get rapped with a hammer.

    Yes, doing this definitely constitutes a "Do at your own risk". If money is tight, run Win 10 unlicensed, until you can a get known legit key from someone like Newegg. Microsoft allows this, so it is perfectly fine to so, and you don't have to risk losing your hard earned cash.
