Important lifecycle notice
Standard Windows 10 support ended on 14 October 2025
Windows 10 can continue to operate, but Microsoft no longer provides standard security updates, feature updates or ordinary technical support. Extended Security Updates may be available separately for eligible Windows 10 version 22H2 devices; ESU is not included with this product.
Start with the use case
Buy Windows 10 only when the requirement is clear
Potentially suitable when
- A verified application, peripheral or specialist device still requires Windows 10.
- The PC has compatible Windows 10 drivers and meets the practical hardware requirements.
- You understand the end-of-support position and have an ESU, isolation or migration plan.
- You need Pro features such as BitLocker, Remote Desktop hosting or domain join.
Choose another option when
- You are buying for a new PC that supports Windows 11.
- You expect free standard Windows 10 security updates from Microsoft.
- You require a transferable licence or expect to replace the HDD or motherboard.
- You need Apple Mac software, Windows Enterprise, LTSC, ESU or Microsoft 365.
Digital fulfilment
What you receive
Typical delivery: 1–10 minutes after successful payment verification. Security checks or an order requiring clarification can take longer.
Read before activation
Licence channel, device binding and transfer limits
Each activated PC uses part of the selected device allowance. This offer is sold on a device-bound basis regardless of the activation channel supplied. An activated device cannot be replaced with another PC under the same allowance.
A Windows reinstall may be activated again on the same PC when its HDD and motherboard have not changed. A new PC, motherboard replacement or HDD replacement can prevent reactivation and requires a new licence.
Do not purchase on the assumption that the key is transferable. Microsoft licence terms govern the underlying software, while this listing’s supplied-key and replacement conditions govern the merchant offer.
Professional capabilities
What Windows 10 Pro adds
BitLocker
Encrypt compatible operating-system and data drives, with recovery information stored safely outside the PC.
Remote Desktop host
Allow an authorised user to connect to the Pro PC from a supported client when the host and network are configured securely.
Domain and Entra join
Connect eligible business PCs to Active Directory or Microsoft Entra ID for managed identity and resource access.
Group Policy
Apply local or domain-based Windows settings in a more consistent, documented way.
Client Hyper-V
Run virtual machines on compatible 64-bit hardware with SLAT, firmware virtualisation and sufficient memory.
Assigned Access
Create controlled kiosk or task-focused experiences where the deployment and application support the scenario.
Feature availability depends on hardware, drivers, connected services, policies and the installed Windows 10 release. Windows edition alone does not create a secure or compliant environment.
Choose the right edition
Windows 10 Home, Windows 10 Pro or Windows 11 Pro?
| Choice | Best fit | Important limitation |
|---|---|---|
| Windows 10 Home | Basic legacy personal use without Pro management features. | Standard support ended; no BitLocker management, Remote Desktop host or domain join. |
| Windows 10 Pro | A validated legacy requirement needing Pro security or management capabilities. | Standard support ended; this offer is device-bound after activation. |
| Windows 11 Pro | Compatible professional PCs needing Microsoft’s current Windows platform. | Requires newer hardware and application, driver and peripheral validation. |
Compare Windows 11 Pro before ordering when the target PC meets its requirements.

Windows 10 minimum system requirements

Activation assurance
Support, replacement and refund commitment
Remote assistance, chat and email support are included for eligible installation and activation issues. If activation does not succeed, Software Mart will first check the edition, installation, device history, error message and all available activation options.
If Software Mart cannot activate the product after completing those checks, the key will be replaced in full or the order will receive a 100% refund.
The commitment does not cover transfer to another PC, an HDD or motherboard change after activation, an unsupported edition, incompatible hardware, customer data loss, or products and services not included in this listing.
Buying questions
Windows 10 Pro FAQs
Is this product for Apple Mac?
No. This product is for compatible Windows PCs. It does not license macOS or supply Windows virtualisation software for a Mac.
Which licence channel will I receive?
The supplied key may use the Retail, OEM or MAK channel depending on available stock. This listing is device-bound and non-transferable after activation regardless of the channel supplied.
How do multi-PC options work?
You receive one multi-device key covering the number of PCs selected above. Each activated PC consumes one permitted activation.
Can I move an activated licence to another PC?
No. An activated allowance cannot be moved to a new computer. A motherboard or HDD change can also prevent reactivation.
Can I reinstall Windows on the same PC?
Yes, provided the same PC retains its HDD and motherboard. Back up first and reinstall the Windows 10 Pro edition that matches the key.
Does the purchase include Windows 10 ESU?
No. Consumer and commercial ESU arrangements are separate and subject to Microsoft eligibility, enrolment dates and terms.
Can this upgrade Windows 10 Home to Pro?
A valid Pro key can upgrade an activated Windows 10 Home installation through Settings → Update & Security → Activation → Change product key. Back up before changing editions.
How quickly will the email arrive?
Normal delivery is 1–10 minutes after successful payment verification. The email contains the key, download links and installation instructions.
What if activation fails?
Contact support with the exact error and device details. After all available activation options are checked, an unresolvable product-activation failure qualifies for a replacement key or 100% refund.
Should I choose Windows 11 instead?
Usually yes when the PC and required applications support it. Windows 10 Pro is most appropriate for a verified legacy requirement with a documented security and migration plan.
