Microsoft charges $139 for Windows 11 Home in its US store. Unlike in the EU, US courts generally treat a Windows licence as something you use, not something you own – which makes reselling a “used” key legally risky.
Key points
- Microsoft lists Windows 11 Home in the US store at $139 as of November 13, 2026.
- In Vernor v. Autodesk (9th Cir. 2010), a federal appeals court held that a software recipient is often a licensee, not an owner – so the first-sale doctrine (17 U.S.C. § 109) usually does not protect resale of “used” software keys.
- Check edition, activation status, and seller information before buying – a low price is not proof of a lawful sale.
Buying a Windows 11 licence in the US means comparing Microsoft’s own store price against third-party key sellers, in a legal environment that treats software resale very differently than EU law does.

What Windows 11 Home costs in the Microsoft US store
The Microsoft US store listed Windows 11 Home at $139 on the day of research. That is an official reference price for one specific product and sales channel, not a legal floor. Third-party marketplaces sell retail, OEM, system-builder, and “used” keys at lower prices; a large gap to Microsoft’s own price says nothing by itself about whether a given key is legitimate.
Microsoft distinguishes between a 25-character product key and a digital license tied to a Microsoft account without entering a key. Before buying anything, check Settings > System > Activation to see whether your device already holds a valid license – especially if you are only reinstalling Windows on the same machine.
Why reselling a “used” license key is legally risky in the US
Software in the US is typically licensed rather than sold outright, and the first-sale doctrine under 17 U.S.C. § 109(a) — which lets the owner of a lawfully made copy resell it — only protects someone who actually owns that copy. In Vernor v. Autodesk, Inc., 621 F.3d 1102 (9th Cir. 2010), the Ninth Circuit Court of Appeals held that a recipient is a licensee rather than an owner where the publisher’s agreement (1) says the transfer is a license, (2) significantly restricts the ability to transfer the software, and (3) imposes notable use restrictions. Because Autodesk’s license met all three conditions, the court found that neither the original customer nor the reseller who later tried to sell a “used” copy was protected by first sale – both infringed Autodesk’s distribution right.
The practical effect for Windows buyers: publisher license terms typically restrict transfer, and under Vernor that restriction usually holds up in court, unlike the position in the EU after the CJEU’s UsedSoft ruling. Marketplaces for “used” or OEM keys still operate in the US, and legal risk in practice tends to fall more on the party reselling than on an ordinary buyer – but there is no guaranteed US right to resell a software license the way there now clearly is in the EU and the UK.
Check system requirements before buying
Regardless of where you buy it, Windows 11 requires a supported processor, at least 4 GB of RAM, at least 64 GB of storage, UEFI with Secure Boot capability, and TPM 2.0. Setting up Home or Pro for personal use also requires an internet connection and a Microsoft account. Use Microsoft’s official compatibility check or your device manufacturer’s guidance before buying a license.
Five-point buying checklist
- Is Windows on your existing device already activated?
- Does your PC meet the official Windows 11 requirements?
- Is it clearly stated which edition and which type of license (retail, OEM, digital, used) is being sold?
- Does the seller provide an invoice, a business name, and a clear return or refund policy?
- Are you comfortable with the legal uncertainty around “used” license resale under Vernor v. Autodesk?
If you cannot answer one of these questions, do not order under time pressure. A short written question to the seller often clarifies more than a low price alone.
Frequently asked questions
How much does Windows 11 Home cost at Microsoft US?
The Microsoft US store listed Windows 11 Home at $139 on November 13, 2026. The price can change and applies to that specific product, not automatically to third-party offers.
Is it legal to resell a used Windows license key in the US?
It is legally contested. Under Vernor v. Autodesk, courts generally treat software recipients as licensees rather than owners, so the first-sale doctrine typically does not protect resale when the publisher’s license restricts transfer.
Where can I complain about a misleading software license offer?
The Federal Trade Commission (FTC) handles deceptive and unfair practices nationally; state Attorneys General and state consumer protection offices handle complaints at the state level.
