We love Windows and Office as much as the next person, but we have to admit that Microsoft products can be fairly expensive. Paying hundreds of dollars for a Windows product key or getting a Microsoft 365 subscription doesn’t make sense when there are more affordable solutions. But what can you do?

Affordable, genuine software

Brytesoft, for instance, offers cheap Windows and Office keys. Even better, these keys come with a lifetime warranty, so you won’t have to worry about it until there’s a new version you want to upgrade to.

And we get it—you’re probably worried about whether or not the keys are going to be valid or whether you’re wasting your money. With Brytesoft, however, that shouldn’t be a concern because this is a retailer that’s been around for almost 15 years and has a Trustpilot rating of 4.7 stars with over 6,200 reviews.

It doesn’t only sell you product keys, every purchase comes with a lifetime warranty, 24/7 technical support, a money-back guarantee, and instant delivery. Step-by-step download and product activation guides are also provided to ensure a seamless activation.

PCWorld readers are getting a little something special. For your first purchase at Brytesoft, you can get 15% off by using the code PCWORLD15 at checkout. There’s no expiration date on our discount code, so you can use it whenever you take the plunge and finally decide to stop spending a fortune on Windows and Office products.

The discount code applies to all products at Brytesoft.

Windows 11 Pro

It’s time to upgrade your system to Windows 11 Pro. It’s only $39.90 at Brytesoft, but you can save more if you buy in bulk. Three product keys will lower the price by $2/piece, but if you buy 10 you’ll save 25%, which is great news for companies looking to upgrade their office PCs. With our discount code, you’ll save an additional 15%.

These are OEM product keys that offer you unrestricted lifetime use, and they cover both 64-bit and 32-bit versions with automatic updates, so you don’t have to worry about it again. It’s a one-time purchase so you’re good to use the key as soon as their email lands in your inbox.

Microsoft Office 2021 Professional Plus

If you refuse to use Microsoft 365 and definitely don’t want to pay for a monthly subscription, you can still get Microsoft Office 2021 Professional Plus for $59.99. If you’d rather get product keys to go with five PCs, you’ll get a lower rate and only pay $249.99 for the whole batch. With our discount code, one license will cost you $50.99, while five of them will cost $212.49.

The software works with Windows 10 or Windows 11, and the license key will work with both the 64-bit and 32-bit versions.

Windows Server

IT companies looking to cut software costs can also get their hands on keys for the Windows Server 2025 Standard for $599.99 and Windows Server 2025 Datacenter for $1,499.99 via Brytesoft. Add in the 15% discount, and you can get the Standard version for $509.99 and the Datacenter one for $1,274.99.

While the standard version will cover activation for 16 cores and two virtual machines, the Datacenter option covers the same number of cores, but an unlimited number of virtual machines.
