General answers for software selection, compatibility, subscriptions, and activation. The individual product page remains the source for offer-specific terms.
Is a product key the same as a license?
No. A product key can be used for activation, but the license terms define the actual usage rights. Successful activation alone does not prove the origin, transferability, device rights, or geographic scope of an offer.
How do I know whether software is compatible?
Check the exact operating-system version, processor architecture, supported hardware, storage, memory, account requirements, and any feature-specific requirements. Use the official manufacturer tools and requirement pages linked from the product page.
What is the difference between a one-time purchase and a subscription?
A one-time purchase normally covers a specific release and does not include future major versions. A subscription is tied to a stated term and can include services, storage, ongoing feature updates, and renewal rules.
Can I use one license on several devices?
Only when the specific offer and applicable license terms state that device or user count. Do not infer device rights from the product family name.
Are all products delivered instantly?
No general delivery promise applies. The product page must state the actual delivery or provisioning method. Microsoft 365 Business subscriptions, for example, can require tenant and CSP provisioning rather than a downloadable key.
Can I return digital software?
Digital-content withdrawal and refund rules depend on the product, fulfillment state, customer consent flow, and applicable law. The store policy must be reviewed before purchase.
