Upgrade Windows 11 Home to Pro without reinstalling
Most laptops and prebuilt desktops sold in the US come with Windows 11 Home. That is fine until the day you need to encrypt the drive with BitLocker, let a colleague connect through Remote Desktop, spin up a Hyper-V virtual machine or join the PC to your company's domain. At that point you have two choices: wipe the machine and install Windows 11 Pro from scratch, or upgrade Windows 11 Home to Pro in place with an upgrade key. This product is the second option.
The upgrade works through a feature Microsoft built into Windows itself. Under Settings, System, Activation, the Change product key button accepts a Pro key on a Home installation. Windows verifies it, downloads the Pro components, restarts once and comes back as Windows 11 Pro with every file, setting and program intact. There is no installation media to create and no reactivation of Office or other software. Our email gives you the key and a short guide; the whole job usually fits inside a coffee break.
Who this upgrade key is for
Remote employees whose employer requires BitLocker or domain join on a personally owned laptop
Freelancers and consultants who need Remote Desktop hosting to reach their office PC from the road
Developers who want Hyper-V and Windows Sandbox on a machine that shipped with Home
Home users who bought a Home laptop and now want Group Policy or Windows Update for Business controls
Anyone who prefers to keep a working, configured Windows install rather than start over
If your PC does not yet have an activated copy of Windows, or you are building a new machine, you need a full license rather than an upgrade. In that case choose our Windows 11 Pro key for 1 PC. If the PC is on Windows 10 Home, the equivalent product is our Windows 10 Pro upgrade key, linked under Related products below.
Signs that it is time to upgrade Windows 11 Home to Pro
You probably need Pro if any of these sound familiar. Your employer's IT department asked you to turn on BitLocker and you cannot find it. You tried to connect to your desktop from a laptop and Windows said Remote Desktop hosting is not available in this edition. A tutorial for a virtual machine told you to enable Hyper-V and the option was missing. You wanted to delay a feature update or change a privacy default and there was no Group Policy editor. Or you simply want to join a work domain. Each of those is a Pro-only capability, and each is switched on the moment you upgrade Windows 11 Home to Pro with this key.
What changes when Home becomes Pro
The Windows 11 Home vs Pro difference is entirely about management, security and hardware limits. The table lists what the upgrade key switches on. Everything you already have in Home stays.

How the upgrade works, step by step
Open Settings, then System, then Activation. Next to Upgrade your edition of Windows, select Change product key and type the 25-character key from your email. Windows contacts Microsoft's activation servers, confirms the key is a genuine Pro key, and shows an Upgrade your edition prompt. Select Start. Windows downloads the Pro components, applies them and restarts once. When the desktop returns, the Activation page reads Windows 11 Pro and shows an activated status. That is the whole procedure to upgrade Windows 11 Home to Pro; the Download and Install tab on this page repeats it with exact menu paths for reference during the process.
Before you start: requirements
Because this key upgrades an existing installation, the requirements are about the current state of the PC rather than raw hardware. Windows 11 Home already running means the machine has passed the TPM 2.0, UEFI Secure Boot, 4 GB RAM and 64 GB storage checks.
The PC must run Windows 11 Home (not Windows 10 Home, and not an N or S mode edition; leave S mode first if it is enabled)
Windows 11 Home must already be activated; check under Settings, System, Activation
An internet connection during the upgrade so Windows can verify the key and fetch Pro components
Administrator access to the PC and a few minutes for one restart
Recommended: Windows Update fully applied and a recent backup, as good practice before any edition change
What the upgrade does not change
The edition change leaves the rest of the PC alone. Manufacturer drivers, the recovery partition and the warranty status of a Dell, HP, Lenovo or ASUS laptop are untouched. Installed software, including Office, Adobe apps and games, keeps its activation. Your Windows Hello PIN, saved Wi-Fi networks and browser sessions remain. The Windows 11 version number stays the same; you are changing edition, not release. Performance does not change either, since Home and Pro share the same kernel and scheduler. What you gain is a set of switches that were greyed out or absent before, now available under Settings and in the Windows Features dialog.
Licensing explained
After the upgrade the PC holds a perpetual Windows 11 Pro license. It is a one-time purchase with no subscription and no renewal. Signing in with a Microsoft account after the upgrade stores the new Pro digital license with that account, which lets you reinstall Windows 11 Pro on the same PC later without entering the key again.
What about the original Home license
The Home license that came with the PC is superseded by the Pro activation on that machine. If the original Home license was OEM, it remains bound to that hardware. The upgrade covers one PC; a second Home laptop needs a second upgrade key. Whether the resulting Pro license can move to another computer depends on the license type, which is stated in the Product Overview table on this page. Our FAQ describes retail, OEM and volume transfer rules in plain language.
Upgrade key or full Pro key
Both end with Windows 11 Pro on your PC. The upgrade key is designed for machines that already run activated Home. The full key also covers clean installs and unlicensed PCs. If you plan to reformat the drive and start fresh anyway, a full Windows 11 Pro product key is the more flexible choice.
Do gamers and home users need to upgrade Windows 11 Home to Pro
Usually not. Games, streaming, photo editing and web apps run identically on Home and Pro; frame rates, DirectX 12 features and hardware support up to 128 GB of RAM are the same. The upgrade is worth it for a home user in a few specific cases: you want BitLocker on a laptop that leaves the house, you want to reach your gaming PC from work through Remote Desktop, or you run virtual machines for tinkering. If none of those apply, keep Home and spend the money elsewhere. We would rather tell you that than sell an upgrade you will not use.

Order the upgrade key, open Settings, System, Activation, choose Change product key and paste the 25 characters. One restart later your PC runs Windows 11 Pro. Our how it works page covers delivery and activation in detail, and the FAQ answers the common questions about upgrades, transfers and refunds.
Download and install
The delivery email arrives within minutes of payment with your 25-character Windows 11 Pro upgrade key and this guide. You do not need installation media; the upgrade happens inside your existing Windows 11 Home installation.
Confirm the PC runs activated Windows 11 Home under Settings > System > Activation. If S mode is enabled, switch out of S mode first.
Save your work, connect to the internet and run Windows Update if updates are pending.
In Settings > System > Activation, select Change product key (or Change next to Upgrade your edition of Windows).
Type the 25-character upgrade key and select Next, then Start.
Windows verifies the key and downloads the Pro components. Do not turn the PC off. It restarts once during the upgrade.
After the restart, return to Settings > System > Activation. The edition should read Windows 11 Pro and the status Windows is activated.
Sign in with a Microsoft account so the Pro digital license is stored for future reinstalls.
If the upgrade stalls or Windows asks for phone activation, reply to your order email with the error code or the Installation ID and we will send the Confirmation ID and next steps. Support is answered by a person seven days a week.
Frequently asked questions
Will I lose my files, programs or settings when I upgrade Windows 11 Home to Pro?
No. The upgrade is an edition change inside your existing installation, not a reinstall. Documents, photos, installed programs, browser profiles, Wi-Fi passwords and personalization all stay in place. Windows downloads the Pro components, restarts once and returns to the same desktop with the Pro features switched on. We still recommend a backup before any system change as a matter of good practice, but the upgrade itself is designed to preserve everything.
How long does it take to upgrade Windows 11 Home to Pro?
For most PCs the process is short: a few minutes for Windows to verify the key and download the Pro components, one restart, and a couple of minutes to finish configuring. A slow internet connection or an older drive can stretch it. Keep the PC plugged in and do not power it off during the restart. When it is done, Settings, System, Activation shows Windows 11 Pro and an activated status.
What is the difference between this upgrade key and a full Windows 11 Pro key?
Both keys switch a PC to Windows 11 Pro. The upgrade key is meant for a PC that already runs genuine, activated Windows 11 Home, and is used through Change product key. The full Windows 11 Pro key can do the same on a Home PC and can also activate a clean installation on a PC with no license, such as a new build. If your PC is unactivated, or you plan to wipe it, buy the full key instead.
My laptop came with OEM Windows 11 Home. Does the upgrade work on it?
Yes. Preinstalled OEM Home is the most common starting point when customers upgrade Windows 11 Home to Pro. Enter the key under Settings, System, Activation, Change product key, and the laptop moves to Windows 11 Pro while keeping the manufacturer's drivers and software. The original OEM Home license stays associated with that hardware. Whether the resulting Pro license can later move to another machine depends on the license type shown in the Product Overview table on this page.
Can I use this key on a Windows 10 Home PC or on Windows 11 Home N?
No. This key is specifically for upgrading Windows 11 Home to Windows 11 Pro. For Windows 10 Home we sell a separate Upgrade to Windows 10 Pro key, or you can first move the PC to Windows 11 Home if the hardware meets the requirements. N editions are a separate product family, so Home N would require Pro N media and a Pro N key rather than this upgrade. If you are not sure which edition you have, check Settings, System, About before ordering.
What if the upgrade fails or the key is rejected? Is there a refund?
Contact us first; most rejections have a simple cause such as S mode still being enabled, no internet connection, or the PC not yet activated on Home. Send us the exact message or error code by replying to your order email, and a person on our team will help seven days a week, including phone activation if Microsoft asks for it. If the key cannot be used to complete the upgrade and we cannot fix it, our 30-day money-back guarantee gives you a replacement key or a full refund.
