Key Takeaways
- Windows 10 reached end of support on 14 October 2025: No more security updates. Extended Security Updates (ESU) are available as a paid stopgap.
- Small business or startup → Windows 11 Pro: BitLocker, Group Policy, Intune and domain join cover most SMB needs.
- 300+ managed devices → Windows 11 Enterprise: Adds Credential Guard, Defender for Endpoint and Autopilot via volume licensing.
- Fixed-function devices (kiosks, medical, industrial) → IoT Enterprise LTSC: 10 years of security updates, no feature updates.
- Check TPM 2.0 and Secure Boot first: If your hardware fails the check, no edition will install.
Windows 10 reached its end of life on 14 October 2025. Microsoft no longer issues security updates or provides technical support for it, which leaves unpatched machines exposed to malware and creates compliance problems for regulated businesses.
Upgrading to Windows 11 is the practical answer. But Microsoft sells six editions, and the differences matter: picking Enterprise when Pro would do wastes money, while picking Home for a business machine leaves you without BitLocker or Group Policy.
This guide explains what changed, compares the Windows 11 editions side by side, covers the license types you will be offered, and sets out what to check before you upgrade.
What Windows 10 End of Life Actually Means
End of life means Microsoft has stopped shipping security patches, quality updates and technical support for Windows 10.
Your PCs still boot and your software still runs. The risk is cumulative: every vulnerability discovered after 14 October 2025 stays unpatched. For businesses handling customer data, that also creates problems under frameworks like PCI DSS and GDPR, which expect supported, patched systems.
Note: If you cannot upgrade immediately, Microsoft offers Extended Security Updates (ESU), which is a paid annual subscription delivering critical security updates only. It is a bridge, not a destination: no new features, no general support, and the cost typically rises each year. Check Microsoft's current ESU pricing and eligibility before budgeting for it.
Which Windows 11 Edition Is Best For Your Business?
The short version:

A Closer Look at Each Edition of Windows 11
Windows 11 Pro
Best for: startups and small to medium businesses.
- BitLocker Drive Encryption protects data on lost or stolen laptops. Often the single most important business feature.
- Group Policy and Microsoft Intune let you manage settings, updates and security policies across machines from one place.
- Microsoft Entra ID (formerly Azure AD) and domain join handle user identity and resource access.
- Hyper-V and Windows Sandbox run virtual machines and test untrusted software safely.
Why choose it: Pro is the baseline for business use. If you manage fewer than a few hundred machines and do not need Credential Guard or Autopilot, Pro covers you.
Windows 11 Pro for Workstations
Best for: high-performance, data-intensive work.
- Supports up to four physical CPUs and 6TB of RAM, far beyond Pro's limits.
- ReFS (Resilient File System) detects and repairs data corruption automatically.
- Persistent memory and SMB Direct move large files faster.
Why choose it: if your team runs simulations, 3D rendering, video production or large datasets, and machines are genuinely workstation class, the extra headroom is worth it. For ordinary office PCs it is money wasted.
Windows 11 Enterprise
Best for: organisations with complex IT and compliance needs.
- Windows Hello for Business and Credential Guard isolate credentials from the rest of the OS.
- Microsoft Defender for Endpoint adds detection and response beyond standard Defender.
- Windows Autopilot and Endpoint Manager provision devices at scale and ship a laptop to a new starter and it configures itself.
Why choose it: once you are managing hundreds or thousands of devices, the deployment and security tooling is what you are paying for. Enterprise is sold through volume licensing.
Windows 11 Education
Best for: schools, colleges and universities.
Windows 11 Education is functionally close to Enterprise, licensed for academic institutions. It includes classroom management, device lockdown and kiosk mode, plus the security features staff and student data require.
Why choose it: if you qualify academically, it gives you Enterprise-class capability under education licensing.
Windows 11 IoT Enterprise LTSC
Best for: fixed-function devices that must not change.
- 10 years of security and quality updates, with no feature updates.
- Designed for embedded and single-purpose systems: kiosks, ATMs, medical equipment, industrial controllers.
Why choose it: when a device has been validated or certified for a specific task, feature updates are a liability rather than a benefit. LTSC keeps it patched and otherwise unchanged.
Why not to choose it: LTSC is not a way to avoid updates on ordinary office PCs. Microsoft licenses it for fixed-function devices, and it omits the Microsoft Store and several bundled apps.
Windows 11 Home
Best for: personal use, families and gaming.
Windows 11 Home includes device encryption, firewall and Windows Hello, plus gaming features like Auto HDR and DirectStorage. It lacks BitLocker, Group Policy, domain join and Intune.
Why it appears here: most consumer laptops ship with 11 Home, so businesses buying off-the-shelf hardware encounter it constantly. If that machine is going to be used for work, upgrade it to Pro rather than leaving it unmanaged.
General Availability Channel vs LTSC
Windows 11 has two servicing channels:
General Availability Channel (GAC): It delivers one annual feature update plus monthly security patches. This is the default and the right choice for almost every business PC.
Long-Term Servicing Channel (LTSC): It delivers security and quality updates for up to 10 years with no feature updates. It is intended for fixed-function devices in healthcare, manufacturing and similar settings.
Choose GAC unless you have a specific device that must stay functionally frozen.
Windows 11 Retail, OEM and Volume Licenses - What's the Difference?
This is where most buyers get caught out, and it matters more than the edition choice for some businesses.
| License type | Transferable to a new PC? | Best for |
| Retail (FPP) | Yes, deactivate on the old machine, activate on the new one | Businesses that replace hardware and want to keep the license |
| OEM | No, permanently tied to the first machine it activates on | Lowest cost per seat when the license retires with the PC |
| Volume (MAK / KMS) | Managed centrally under a licensing agreement | Organisations deploying across many machines at once |
Why this matters: an OEM license is cheaper because it cannot move. If you refresh laptops every three years and expect to carry licenses across, buy retail. If the license dies with the hardware, OEM is the economical choice.
Msckey supplies retail, OEM and volume license keys, and each product page states which type you are buying. Every key comes with a 30-day money-back and replacement guarantee. If a key does not activate, contact support within 30 days with your order number and the error message, and you will get a replacement or a refund. Full terms are in our Terms and Conditions.

Before You Upgrade to Windows 11: A Checklist
- Check system requirements: Windows 11 requires TPM 2.0, Secure Boot, a compatible 64-bit CPU, 4 GB RAM and 64 GB storage. Run Microsoft's PC Health Check on a sample machine from each hardware generation you own. This is the step that stops most upgrades.
- Back up your data: Full backup to external storage or cloud before touching anything.
- Test business-critical applications: Most software carries over, but legacy 32-bit applications, old printer and scanner drivers, and bespoke line-of-business tools do sometimes break. Test on one machine before rolling out.
- Decide your license type: Retail if licencss need to move between machines; OEM if they retire with the hardware; volume if you are deploying at scale.
- Plan the rollout: Upgrade in waves, starting with a pilot group. Train staff on the new interface like Start menu, Snap Layouts and settings have all moved.
FAQs
What happens now that Windows 10 is no longer supported?
Your PCs keep working, but Microsoft no longer issues security updates or provides support. Every vulnerability found after 14 October 2025 stays unpatched, so risk accumulates over time. Upgrade to Windows 11, or buy Extended Security Updates as a temporary bridge.
Can I upgrade from Windows 10 to Windows 11 for free?
Yes, if your hardware meets the requirements. Microsoft offers a free upgrade path from a genuine, activated Windows 10 license key. If your hardware fails the check, or you need a different edition, you will need a new license.
What is the best Windows 11 edition for my business?
Under about 300 managed devices, Windows 11 Pro covers most needs. Above that, 11 Enterprise's deployment and security tooling starts to pay for itself. Schools should use 11 Education. Kiosks and embedded devices should use IoT Enterprise LTSC.
Will my applications work on Windows 11?
Most will. Applications that ran on Windows 10 generally run on Windows 11 without changes. Exceptions do exist legacy 32-bit software, older hardware drivers and some bespoke business applications. Test anything business-critical before rolling out.
What is the difference between Windows 11 retail, OEM and volume licenses?
A retail license can be moved to a new PC. An OEM license is permanently tied to the first machine it activates on, which is why it costs less. Volume licenses are managed centrally for larger deployments.
Can I upgrade Windows 11 Home to Pro?
Yes. Microsoft charges $99.99 for the in-place upgrade; Msckey sells a Windows 11 Pro upgrade key for $29.99. Your files and applications stay in place.
Choosing Your Edition
Windows 10's end of support makes upgrading a security and compliance requirement rather than a preference. The edition decision is simpler than the six-way menu suggests: Windows 11 Pro for most businesses, Enterprise once you are managing hundreds of devices, LTSC only for fixed-function hardware and Education for academic institutions.
Check your hardware first. TPM 2.0 and Secure Boot are the gatekeepers, and machines that fail them need to be replaced or have an ESU subscription, regardless of which edition you would have chosen.
