How much does Windows 11 Pro cost and how not to overpay
The right price depends on what you already have.
You have activated Windows 10 Pro
The upgrade to Windows 11 Pro is free.
You have Windows 11 Home
You pay only for the edition change. A Pro key does the job.
You have no licence
You need a full key. Prices differ by licence type: OEM stays with one PC, Retail can move.
New PC with Windows preinstalled
The licence is in the price, so check the edition first.
What makes prices differ
Licence type, seller, and refund terms. A price far below the market with no refund policy is a warning sign: see how to buy digital keys safely.
Is the Microsoft Store the only safe place?
No, but check the seller. Read [Microsoft Store or key shop](microsoft-store-or-key-shop/).
