Choose the exact product and license conditions you need, complete checkout, then follow the instructions supplied for that order. Software in Store provides the order support described here; it is an independent reseller, not Microsoft support.
1. Confirm the product before paying
- Check the edition, platform, supported operating system and hardware. Windows 11 requires compatible 64-bit hardware; a key does not make unsupported hardware compatible.
- Confirm device or user allowance, license channel, geographic restrictions and whether an existing qualifying license is needed.
- Check the product’s Microsoft support lifecycle. A perpetual license does not promise future versions or security updates forever.
- If the listing is unclear, ask support@softwareinstore.com before ordering.
2. Review checkout
Check the product and final amount shown at checkout and enter an email address you can access. Available payment methods are shown at checkout. Read the Terms of Service, Refund Policy and Privacy Policy before purchasing.
3. Receive the order email
Digital delivery is normally within minutes after successful payment. Payment review or a technical issue can delay delivery. The email contains the key and the applicable download or redemption instructions. No physical package is shipped. If it has not arrived after 30 minutes, check spam, confirm the email on your order, and contact us with your order number. See the Delivery Policy.
4. Use the correct official installation route
- Windows: check your installed edition in Settings before changing a key. Use the applicable Microsoft Windows download page. Back up your files before reinstalling or changing editions.
- Office retail redemption: where your purchased license supports account redemption, use setup.office.com with your own Microsoft account. Follow the instructions specific to the supplied edition.
- Volume-licensed Office and other business software: use the deployment and activation method permitted by your organization’s license. Retail account redemption is not interchangeable with volume activation.
- Visual Studio: install the matching Professional edition from Microsoft and use the licensing instructions for that version. A product key does not include subscription extras unless expressly listed.
5. Check the result and keep the records
Check that the installed edition matches your order and that activation completed. Activation confirms that a product key was accepted; it does not, by itself, establish ownership, genuine status, transfer rights or compliance with the applicable license agreement. Keep your invoice and licensing documentation. Transfer and reinstall rights depend on your license; removing a key from one device does not automatically make it transferable.
If an activation step fails
Contact support@softwareinstore.com with your order number, edition and the exact error. Do not send your Microsoft-account password, full card details or a screenshot showing the entire key. Use only the activation options Microsoft presents for your product; do not run third-party activators or disable security protections.
Our 180-day guarantee
If a covered key or product issue is reported within 180 days of purchase and cannot be resolved, choose a replacement or full refund under our Refund Policy. This guarantee is separate from Microsoft licensing rights and support lifecycles.
