Windows 11 Home costs $139 and Windows 11 Pro costs $199 when you buy them separately from Microsoft

If you are buying a new computer, Windows 11 usually comes pre-installed and you do not pay extra — the license cost is built into the price the manufacturer charges you. If you are upgrading an existing machine or replacing a damaged Windows installation, you buy a license directly from Microsoft or an authorized retailer for one of two versions.

The price difference between Home and Pro is $60. Home covers most personal use: web browsing, email, gaming, streaming, document editing. Pro adds features for small business or technical users — remote desktop access, encryption tools, the ability to join a corporate domain, and more frequent security updates. Most home users never need Pro.

These prices are what Microsoft lists on its official store. Authorized retailers like Best Buy, Amazon, or Newegg sometimes run sales or bundle discounts, but the base price stays the same across them.

Key Takeaways

  • Windows 11 Home is $139 and Windows 11 Pro is $199 when purchased separately; most home users need only Home.
  • If your computer came with Windows 11 pre-installed, the license cost was already paid by you through the purchase price.
  • You can use Windows 11 without a license for an unlimited time, but you will see a watermark on your desktop and cannot customize certain settings.
  • A license is tied to your device hardware, not to you personally, so if you replace your motherboard or major components, you may need to reactivate or repurchase.
  • Educational institutions, nonprofits, and some businesses may have access to Windows through volume licensing programs at different prices.

What you get when you buy a license versus using Windows unlicensed

An unlicensed copy of Windows 11 will run on your computer indefinitely. You can install software, browse the web, and do most everyday tasks. The main restrictions are visual and functional: a watermark reading "set up Windows" appears in the bottom right corner of your screen at all times, and you cannot change your desktop background, lock screen, or accent colors.

When you set up a license, that watermark disappears and you regain access to personalization settings. You also receive the legal right to use the software — without a license, you are using it under a limited evaluation period that Microsoft does not enforce but technically does not permit indefinitely. For most people, the practical difference is the watermark and the settings lockout, not a sudden loss of function.

Security updates work the same way whether your copy is licensed or not. Both receive the same patches and fixes from Microsoft.

Where the price comes from when you buy a new computer

When you purchase a laptop or desktop with Windows 11 already installed, the manufacturer has paid Microsoft a per-unit license fee. That cost is included in what you pay — you are not charged separately, but you are paying for it. The amount manufacturers pay varies based on volume and their contract with Microsoft, but it typically ranges from $50 to $100 per machine.

This is why a computer with Windows costs more than an identical computer without an operating system. The license is non-transferable: if you sell the computer, the license stays with it and transfers to the new owner. If you remove the hard drive and install it in a different computer, the license does not follow — it remains tied to the original machine's hardware.

How to buy a license and set up it on your machine

You can purchase a Windows 11 license from Microsoft's official store at microsoft.com, or from retailers like Best Buy, Amazon, Newegg, or Costco. You will receive a 25-character product key either printed on a card or sent to your email, depending on whether you buy physical or digital.

To set up, open Settings on your Windows machine, go to System, then About, and scroll down to find "set up." Click "Change product key" and enter the 25-character code. Windows will contact Microsoft's servers to verify the key is genuine and has not been used on too many devices already. set up usually completes in seconds.

Once activated, your license is tied to that specific computer's hardware. If you later upgrade your motherboard, processor, or other major components, Windows may ask you to reactivate. You can reactivate using the same product key, but if the hardware change is substantial enough, Microsoft may require you to contact their support line to verify the license is still legitimate.

Refurbished, OEM, and discounted licenses — what the difference means

You may see Windows 11 licenses sold at prices well below the official $139 or $199 — sometimes $20 to $50. These are usually OEM licenses, which are copies intended for manufacturers to pre-install on new computers. Selling them separately is technically against Microsoft's terms, but it happens widely through third-party sellers.

An OEM license is cheaper because it is meant for bulk purchase by manufacturers, not individual consumers. The catch is that OEM licenses cannot be transferred to a new computer if you upgrade your hardware — they are locked to the original machine. A retail license, by contrast, can be moved to a new computer if you uninstall it from the old one first.

If you buy an OEM license from a third-party seller and it does not set up, or if Microsoft later deactivates it as unauthorized, you have no recourse — the seller is not authorized by Microsoft and cannot help you. Buying from Microsoft directly or from major authorized retailers like Best Buy or Amazon carries a may provide that the key is genuine.

Volume licensing and educational pricing

If you work for a business, school, or nonprofit, your organization may have access to Windows through a volume licensing agreement with Microsoft. These programs — called Microsoft Volume Licensing — offer per-unit costs that are lower than retail, sometimes significantly. A school might pay $15 to $30 per license, or provide Windows free to students.

You cannot purchase volume licenses yourself as an individual. Your employer, school, or organization's IT department handles the purchase and assigns licenses to you. If you leave the organization, the license stays with them and is reassigned to someone else.

If you are a student or work for a nonprofit, ask your IT department or help desk whether Windows is available to you at no cost or reduced cost. Many institutions include it as part of their software offerings.

Upgrading from an older version of Windows

If you own a computer with Windows 10, you can upgrade to Windows 11 for free if your hardware meets the system requirements — primarily a compatible processor and at least 4 GB of RAM. Microsoft ended free upgrades in October 2022, but the upgrade path still exists and costs nothing if you are may be able to access.

To check if your machine qualifies, read the PC Health Check tool from Microsoft's website and run it. It will tell you whether your processor, RAM, and storage meet the minimum requirements. If you do not meet the requirements, you cannot upgrade to Windows 11 at all — you must buy a new computer or replace key hardware like your motherboard.

If you own Windows 7 or Windows 8, there is no free upgrade path. You must purchase a Windows 11 license at the full retail price.

Frequently Asked Questions

Can I use the same product key on two different computers?

No. A single retail product key can only be activated on one computer at a time. If you try to set up it on a second machine, the first one will be deactivated. You can move the key to a new computer by deactivating it on the old one first, but you cannot use it simultaneously on two machines.

What happens if I buy a Windows 11 license and then return my computer?

If you purchased Windows 11 separately from the computer, you can return the license within the return window of the retailer you bought it from — usually 14 to 30 days. If Windows came pre-installed on the computer, the license is part of the computer purchase and follows the computer's return policy, not a separate one.

Is Windows 11 Pro worth the extra $60 for a home user?

For most home users, no. Pro is designed for small business owners, IT professionals, and people who need remote desktop access or encryption features. If you are using your computer for work from home, gaming, streaming, or general browsing, Home has everything you need.

Can I get Windows 11 cheaper by buying it from another country?

Product keys are not region-locked, so a key purchased in another country will set up on a US computer. However, prices vary by country based on local purchasing power, and some retailers restrict sales by location. Buying from unauthorized resellers in other countries carries the same risk as buying from unauthorized resellers anywhere — the key may be deactivated later if Microsoft determines it was sold improperly.

Do I have to pay for Windows 11 again if I reinstall it on the same computer?

No. Once a license is activated on a computer, you can reinstall Windows as many times as you want on that same machine without buying a new license. Your product key remains valid for that hardware. If you reinstall and Windows asks for set up, use the same product key you used before.
