Canceling the mistaken Windows 10/11 Pro purchase depends on how and where it was bought. From the available information, the supported path is to treat it as a Microsoft Store purchase and cancel or request a refund through order history.
Follow these steps:
- Go to the Microsoft account order history page: https://account.microsoft.com/billing/orders and sign in with the account used to buy Windows 10/11 Pro.
- Locate the Windows 10/11 Pro order.
- If the Cancel item option is available next to the order, select it.
- Select the check box for the item and then select Cancel item.
- Check email for a cancellation confirmation (including spam/junk folders).
- If Cancel item is not available (for example, already charged or delivered), use the refund path instead by following the guidance under request an exchange or refund from Microsoft Store.
- If confirmation email does not arrive after some time, contact Microsoft Store support using the Help with Microsoft Store purchases entry point and choose the appropriate support option (chat or phone) for the region.
If the Windows Pro license was purchased through a third-party seller (not Microsoft Store), cancellation or refund must be handled through that seller’s support and policies.
