Microsoft Windows 10 Professional Key (20 PC)

What is included in Microsoft Windows 10 Professional?

BitLocker Encryption – Full drive encryption with management policies for stolen laptops.
Hyper-V Virtualization – Native hypervisor for running virtual machines locally.
Remote Desktop Host – Inbound RDP sessions to access this PC remotely.
Domain Join – Joins Active Directory and Microsoft Entra ID networks.

What are the main benefits of Microsoft Windows 10 Professional?

Windows 10 Pro is the business edition of Windows 10 version 22H2, adding domain join, BitLocker, Hyper-V, Remote Desktop hosting, and Group Policy on top of the Home feature set. It targets work PCs, developer machines, and power users who need encryption, virtualization, or central management.

Stable Interface – Classic Start menu and taskbar without forced redesign.
Wide Hardware Range – Runs on older PCs that fail Windows 11 checks.
Workstation Encryption – BitLocker secures internal and removable drives.
Local VMs – Hyper-V hosts test labs without third-party hypervisors.
Remote Work – Hosted RDP sessions reach the PC from outside.
Central Management – Group Policy and MDM control fleet behavior.

Windows 11 Home and Windows 11 Pro? Who needs what and why?
Buyer-side guidance on who actually benefits from Pro features such as BitLocker, Hyper-V, and Remote Desktop hosting.

What does Windows 10 Professional do that Windows 10 Home does not?

It adds five things Home lacks: BitLocker Drive Encryption, Hyper-V, Remote Desktop hosting (inbound RDP), Active Directory / Microsoft Entra ID domain join, and Group Policy. Home is capped at 128 GB RAM; Pro raises that ceiling to 2 TB. For a workshop or office PC that needs to be locked down, joined to a domain, or used as a virtualization host, those gaps are the entire reason to choose Pro. For pure home use such as browsing, games, and Office, Home covers the same daily tasks at lower cost.

How does Windows 10 Pro compare to Windows 11 Pro?

Both editions share the same Pro feature set (BitLocker, Hyper-V, RDP hosting, domain join, Group Policy), but Windows 11 Pro requires TPM 2.0, Secure Boot, and a supported 64-bit CPU on the official compatibility list, while Windows 10 Pro runs on a much wider range of older hardware. Windows 11 Pro also requires a Microsoft Account and internet connection during initial out-of-box setup for the Home/Pro consumer flow. Windows 10 Pro version 22H2 reached end of mainstream support on October 14, 2025; Windows 11 continues to receive feature and security updates. Pick Windows 10 Pro if the hardware fails Windows 11 checks and a TPM 2.0 / Secure Boot upgrade is not possible.

Who is Windows 10 Professional best suited for?

It fits users tied to hardware that cannot pass the Windows 11 compatibility check (no TPM 2.0, unsupported CPU) but still need Pro-level features. Typical cases are a small office PC that must join an Active Directory domain, a developer workstation running Hyper-V VMs, a laptop that must be BitLocker-encrypted before leaving the building, or a desktop accessed remotely by RDP. For a pure home machine used only for browsing and games, Windows 10 Home covers the same daily work without these features. For organizations with AppLocker, BranchCache, or DirectAccess requirements, the Enterprise edition is the correct target instead.

Does Windows 10 Professional still receive security updates?

Mainstream support for Windows 10, version 22H2 (including Pro) ended on October 14, 2025, so no free monthly security or feature updates are delivered through Windows Update by default after that date. Microsoft offers an Extended Security Updates (ESU) program that delivers critical and important security patches through October 13, 2026 for consumers, and up to October 2028 for commercial customers on an annual escalating subscription. ESU does not include new features, non-security bug fixes, or general technical support, and devices must be on version 22H2 to enroll. Buyers staying on Windows 10 Pro should plan ESU enrollment or a Windows 11 migration path before that window closes.

Does Windows 10 Professional support Active Directory and Microsoft Entra ID?

Yes. Windows 10 Pro can join a local Active Directory domain and also join Microsoft Entra ID (formerly Azure AD), including hybrid join for environments that use both. This is the main reason businesses pick Pro over Home: Group Policy from the domain controller, Intune / MDM enrollment, and single sign-on to Microsoft 365 only work once the device is joined. Home cannot join either directory at all and is limited to workgroup networking. If the device will be managed by an IT department or accessed with corporate credentials, Pro is the minimum edition that supports it.

Can Windows 10 Professional host Remote Desktop sessions and run Hyper-V?

Yes, both are included. Windows 10 Pro can act as a Remote Desktop host so other Windows, macOS, iOS, Android, or Linux clients can connect inbound to its desktop over RDP, which Home cannot do — Home only includes the RDP client. Hyper-V on Windows 10 Pro lets the PC create and run virtual machines natively, useful for testing other operating systems, isolating a browser, or running a legacy app without a separate physical machine. Hyper-V needs a 64-bit CPU with SLAT and hardware virtualization enabled in firmware; if those flags are off in BIOS/UEFI, the Hyper-V role will refuse to start even though the feature is licensed.

What should users check before choosing Windows 10 Professional over Windows 11 Pro?

Confirm three things: whether the PC has TPM 2.0 and Secure Boot (required for Windows 11 Pro), whether the CPU appears on Microsoft's Windows 11 supported processor list, and whether any business-critical application has a verified Windows 10-only driver or compatibility note. If TPM 2.0 is missing or the CPU is unsupported, Windows 10 Pro is the highest currently-supported Microsoft desktop edition that will install. If all three checks pass, Windows 11 Pro is the longer-supported option, because Windows 10 mainstream support already ended on October 14, 2025 and ESU coverage for consumers stops on October 13, 2026.

Frequently asked questions about Microsoft Windows 10 Professional

Is a Microsoft Account required to set up Windows 10 Pro?

No. Windows 10 Pro version 22H2 still allows a local account during out-of-box setup without forcing a Microsoft Account sign-in, unlike the current consumer flow on Windows 11. This matters for offline workstations, lab machines, and shared kiosk PCs where a personal Microsoft Account would not be appropriate.

Does Windows 10 Pro include Windows Sandbox?

Yes. Windows Sandbox is available on Windows 10 Pro (and Enterprise) and provides a disposable virtual desktop for opening untrusted files or testing installers, with all changes discarded when the window closes. It requires hardware virtualization to be enabled in firmware, since it is built on the same Hyper-V components.

What is the maximum supported RAM in Windows 10 Pro?

Windows 10 Pro supports up to 2 TB of RAM and up to 2 physical CPU sockets. That headroom matters for workstations running Hyper-V with several VMs in parallel, large databases, or memory-intensive engineering software — scenarios where Home's 128 GB ceiling would block the workload.

Can Windows 10 Pro be upgraded in place to Windows 11 Pro?

Yes, provided the hardware meets the Windows 11 requirements: TPM 2.0, Secure Boot, a supported 64-bit CPU, 4 GB RAM, and 64 GB storage. The in-place upgrade preserves files, apps, and settings, and the existing Pro entitlement carries over to Windows 11 Pro. If TPM 2.0 or a supported CPU is missing, the Windows 11 installer will block the upgrade.

Legal Information About Our Products

keys.express and keys.discount are online platforms for product keys. The product keys available in our shops for Windows and other software are inexpensive, secure, legal and come with an activation guarantee.

Below you will find the most important legal information about our products.

Unused and Non-Activated Product Keys

We offer exclusively unused and non-activated product keys. The keys have never been redeemed for activation and are fully available to the purchaser for the first-time activation of the respective product. A key that has already been redeemed could no longer be used for a new activation and is therefore not offered by us.

Trading in these product keys is permissible in the European Union and in Switzerland under current case law, provided that the necessary conditions are met. These conditions are as follows:

• The software must originally have been placed on the market with the consent of the rightholder within the territory of the EU, another contracting state of the EEA, or Switzerland by way of sale.
• The license for the software must have been granted in return for the payment of a fee intended to enable the rightholder to obtain remuneration corresponding to the economic value of the copy of the software.
• The rightholder must have granted the first acquirer the right to use the software permanently (for an unlimited period).
• Any improvements and updates that the subsequently downloaded computer program has compared to the originally downloaded one must be covered by a maintenance agreement concluded between the rightholder and the first acquirer.
• The original licensee must have made their own copies unusable.

This trade is legally permissible because the underlying license was already placed on the market with the consent of the rightholder within the EU/EEA or Switzerland in return for appropriate remuneration. As a result, the so-called principle of exhaustion has taken effect, which permits the resale of individual product keys — in particular those originating from volume license agreements. Microsoft or the respective software provider has already received appropriate remuneration for this.

keys.express and keys.discount ensure that the aforementioned conditions are met and that the lawful use of the software is guaranteed. The requirements arising from European legislation are also observed in Switzerland.

Important note: The acquisition of a product key through the transmission of a combination of numbers and letters in digital form does not, in itself, constitute a license for the lawful use of the program. The license only arises from the respective installation and the associated acceptance of the manufacturer's terms of use.

Overview of the Most Important Legal Information

• We offer unused, non-activated product keys for the activation of the respective computer programs. The key alone is not yet a license.
• The license only arises from the respective installation and the resulting acceptance of the terms of use. These terms of use govern the right to use the software between you and the respective manufacturer.
• The principle of exhaustion has, as a rule, taken effect — i.e. the license is "used up" — as soon as it was lawfully placed on the market for the first time. The products concerned are software placed on the market for unlimited-time use in the form of an activatable product key with the option to download the program. Microsoft or the respective software provider has received appropriate remuneration for this.
• You gain access to particularly attractively priced product keys from volume license agreements, which are to be treated legally in the same way as parts of volume licenses upon first acquisition.
• The software itself is always the same original software that is also obtained through official download channels or manufacturer sources. You are therefore not paying for a different or inferior version, but for a valid activation key or a corresponding license.
• All brand names and brand logos are registered trademarks, whose use here serves solely for product description — the ownership rights lie with the respective trademark holder.
