Why Windows 10 Pro
Key Features of Windows 10 Pro

🔐 BitLocker Encryption

Encrypt your entire drive with BitLocker to protect sensitive data from unauthorised access — even if your device is lost or stolen. Essential for business and professional users.

🖥 Remote Desktop

Access your Windows 10 Pro PC remotely from anywhere — connect from another device and use your full desktop as if you were sitting in front of it. Pro-exclusive feature not available in Home.

🏢 Domain & Azure AD Join

Join your PC to a corporate domain or Azure Active Directory for centralised management, group policies, and enterprise authentication — required for most business IT environments.

📦 Hyper-V Virtualisation

Create and run virtual machines directly on Windows 10 Pro with Hyper-V. Run multiple operating systems simultaneously without needing third-party virtualisation software.

🪟 Windows Sandbox

Test software in a lightweight, isolated virtual environment that resets completely every time you close it. Perfect for safely running untrusted applications without risk to your main system.

🔧 Group Policy Management

Control security settings, software deployment, and user permissions across your organisation using Group Policy — a powerful management tool available only in Windows Pro and Enterprise editions.

Choose Your Installation Type
Two Ways to Install Windows 10 Pro
Option 1

🖥 Clean Installation

Use this if you: are installing on a new PC with no operating system, upgrading from Windows 7 or 8, or want to start completely fresh. This installs a brand new copy of Windows 10 Pro and removes everything on the drive.

Option 2

⬆ Upgrade from Home to Pro

Use this if you: already have Windows 10 Home installed and simply want to upgrade to the Pro edition without reinstalling. This keeps all your files, apps, and settings intact.

Option 1
Performing a Clean Installation of Windows 10 Pro

Use this method when installing on a new PC, a PC without an operating system, or when upgrading from an older Windows version such as Windows 7 or Windows 8.

1

Download the Windows Media Creation Tool from Microsoft

The Media Creation Tool is the official, free utility from Microsoft for creating Windows 10 installation media. Download it directly from Microsoft's website:

Official Microsoft Download URL
https://www.microsoft.com/en-us/software-download/windows10
💡 This is the official Microsoft download page — the tool is completely free and downloads the latest version of Windows 10 directly from Microsoft's servers.
2

Run the Media Creation Tool & Create Installation Media

1

Run the downloaded tool and select "Create installation media for another PC".

2

Select your preferred Language (e.g. English).

3

Select Edition: Windows 10 — this includes both Windows 10 Pro and Home on the same installation media.

4

Select Architecture: 64-bit (x64) — recommended for all modern PCs. Choose 32-bit only if your hardware specifically requires it.

5

Choose your installation media type:
— USB flash drive (8 GB or larger) — easiest and fastest method
— ISO file — use this to burn a DVD if you prefer a disc

⏳ The tool will download Windows 10 and create the installation media automatically. This typically takes 20–60 minutes depending on your internet speed.
3

Perform the Clean Installation

1

Boot from the USB flash drive or DVD you created. To do this, restart your PC and press the boot menu key (usually F12, F8, Esc, or Del depending on your motherboard — check your PC or motherboard manufacturer's documentation).

2

Select your Language, Time, and Keyboard preferences on the first setup screen, then click Next → Install Now.

3

When prompted for a product key, enter the 25-character Windows 10 Pro key provided by MMKeys. If you want to activate later, click "I don't have a product key" and enter it after installation.

4

Select Windows 10 Pro as the edition to install.

5

For installation type, select "Custom: Install Windows only (advanced)".

6

Delete all existing partitions on the target drive and create a new one, then click Next to start the installation.

⚠ Warning: Deleting partitions will erase all data on the selected drive. Back up any important files before proceeding with a clean installation.
✅ Installation complete! Windows will restart several times during the process. Once complete, follow the setup wizard to configure your region, account, and preferences. Your Windows 10 Pro will be activated automatically if the key was entered during setup.
Option 2
Upgrading from Windows 10 Home to Pro

Use this method if Windows 10 Home is already installed and you want to upgrade to Pro without reinstalling. Your files, applications, and settings will be preserved.

1

Open the Product Key Dialog

Press Windows key + R to open the Run dialog. Type the following command and press Enter:

Run Dialog Command
slui.exe
💡 This opens the Windows Activation dialog directly — the fastest way to enter a product key for upgrading editions.
2

Enter the Default Upgrade Key

Enter your Windows 10 Pro product key from MMKeys directly. If it is not accepted, first apply the default generic key below to trigger the edition upgrade, then activate with your MMKeys key afterward:

Default Windows 10 Pro Generic Key (for edition upgrade only)
VK7JG-NPHTM-C97JM-9MPGT-3V66T
⚠ Error 0x800f0805? If this error appears after applying the generic key, check:
• You have at least 20 GB of free disk space
• Windows is updated to its latest version
If both conditions are met and the error persists, important system files may be missing — perform a clean installation (Option 1) instead.
3

Change Product Key & Complete the Upgrade

1

Go to Start → Settings → System → About and click "Change product key". If User Account Control prompts you, click Yes.

2

Enter your genuine Windows 10 Pro product key from MMKeys and click Next.

3

Make sure all open applications are closed and your work is saved, then click Start to begin the upgrade process.

✅ The upgrade typically takes 5–10 minutes and your computer will restart. Your files, apps, and settings are preserved throughout the process. Once complete, Windows 10 Pro features will be available immediately.
Troubleshooting
How to Troubleshoot Windows 10 Pro Installation
1

Unable to Select Windows 10 Pro During Clean Installation

If the Windows 10 Pro edition option is not available during installation, this is usually caused by the installation media's pre-existing configuration. Fix it by adding an ei.cfg file to the installation media:

  1. Open Notepad and paste the following text exactly:
ei.cfg — File Contents
[Channel]
Retail
[VL]
0
  1. Go to File → Save As and configure the following:
    — File name: ei.cfg
    — Save as type: All Files
    — Encoding: ANSI
    — Save this file to the \sources folder on your USB installation media.
  2. Retry the installation from the USB drive — Windows 10 Pro should now be selectable.

Step 1 — Remove existing key
slmgr /upk
