Windows 11 Professional - How to dowload, install and activate ?

Windows 11 officially launched on October 5, 2021. Ready to upgrade to the new operating system? We've prepared a guide to help you download, install, and set up Windows 11 effortlessly.

The installation process for Windows 11 Professional is straightforward and user-friendly. Most users can stick with the default settings, as the steps are largely self-explanatory. Whether you use the Media Creation Tool or manually upgrade, the process is guided step by step and typically takes only a few minutes. Modern Windows installers are designed to require minimal user involvement.

Before starting the installation, ensure your system meets the hardware requirements. Windows 11 requires TPM 1.2 (ideally version 2.0) and Secure Boot mode for security reasons. These requirements mean that not all hardware is compatible with the operating system.

To confirm compatibility, check that your motherboard supports Windows 11 and verify that your processor is on the compatibility list. You can check your computer's readiness in the Windows Update settings (Settings > Updates and Security). If your system is compatible, you'll see a confirmation message. Note that you need to be running Windows 10 version 2004 or later to proceed with the upgrade.

Option 1: Clean Installation of Windows 11 Pro

This method is recommended if you're using an older version of Windows (prior to Windows 11) or if your PC currently does not have an operating system installed.

1. Preparing Your Device

Before beginning the installation, it's essential to take a few key steps to get your device ready. Proper preparation will help ensure a smooth process and reduce the risk of data loss.

System Requirements for Windows 11 Pro

Before downloading Microsoft Windows 11 Pro, it's important to verify that your device meets the minimum system requirements. Here are the key specifications you’ll need:

• Processor: 1 gigahertz (GHz) or faster with two or more cores on a compatible 64-bit processor or System on a Chip (SoC)
• RAM: 4 GB
• Storage: 64 GB or larger storage device
• System firmware: UEFI compatible, with Secure Boot support
• TPM: Trusted Platform Module (TPM) version 2.0
• Graphics card: DirectX 12 compatible or later with WDDM 2.0 driver
• Display: High-definition display (720p) larger than 9″ diagonally, 8 bits per color channel

If your device meets these requirements, you’re ready to move on to the next steps for preparing to download the Windows 11 Pro ISO.

You can also verify compatibility using Microsoft’s PC Health Check tool.

Backup Your Data

Before starting the installation, ensure you back up all important files and data. While the installation process is typically smooth, there’s always a chance of data loss.

Once you’ve completed these preparation steps, you’ll be ready to download and install Windows 11 Pro.

2. Download Windows 11 Pro

Downloading the Windows 11 Pro installation files is the first step in the installation process. Here’s what you need to do:

1. Navigate to the official Microsoft website and locate the Windows 11 Pro download page.
2. Click the “Download” button and select your preferred language.
3. Download Windows 11 Pro ISO file on your device or create a bootable USB drive using Microsoft’s Media Creation Tool.

Once you have successfully downloaded the installation files, you will be ready to proceed with the installation process itself.

3. Download Windows Media Creation Tool directly from Microsoft:

The Windows 11 Media Creation Tool is a convenient program that simplifies the process of creating installation media for Windows 11. With this tool, you can upgrade your current system to the latest version or create a bootable DVD or USB drive with the installer. The process is automated and user-friendly.

The tool doesn’t require installation. Once launched, it provides two options: upgrading the current system or downloading files to create installation media. It allows you to save the files as an ISO image on your computer or automatically prepare a bootable USB flash drive or DVD. To use the tool, ensure you have at least 8 GB of storage available on your chosen media. The entire process is handled automatically for a seamless experience.

4. Run the Media Creation Tool

1. Create installation media for another PC
2. Select preferred language
3. Select Edition: Windows 11 (it includes both, Pro and Home)
4. Select architecture (64-bit or 32-bit)
5. Select the media you want to create (USB flash drive or ISO file to create a DVD)

5. Perform a clean installation

Once you’ve downloaded the installation files and prepared your device, you’re ready to start installing Windows 11 Pro. Simply follow these steps:

1. Insert the bootable USB drive or mount the ISO file. Ensure that the USB drive is securely connected to a functioning USB port or that the ISO file is properly mounted in your virtual drive software.
2. Restart your computer and enter the BIOS to configure booting from the USB or ISO. The key to access BIOS varies by manufacturer, but common options include F2, F12, or Del — consult your device manual if unsure.
3. Follow the on-screen instructions to select the language, accept the license agreement, and configure installation settings. Take your time to read through each option carefully to ensure you're setting up Windows 11 Pro according to your preferences.
4. Choose “Custom install” and specify the partition for installing Windows 11 Pro. If you're upgrading from a previous version of Windows, consider creating a backup of your important files before proceeding with this step.
5. Wait for the installation process to complete, which may take some time. During this period, your computer may restart several times — this is normal and part of the installation process.
6. After the installation is complete, Windows 11 Pro will be ready for use. However, to fully utilize the system, you will need to activate it using a valid product key.

Option 2: Upgrading from Windows 11 Home to Pro

Upgrading from Windows 11 Home to Pro unlocks a range of powerful features, including mobile device management (MDM), group management tools integrated with the cloud and Windows Server, and access to the Microsoft Store for Business. This upgrade also enables you to publish and download applications, manage user access, activate kiosk mode, and control updates using Windows Update for Business.

If you are currently using Windows 11 Home and want to upgrade to Pro, follow these steps:

1. Press the "Windows key" + "R", type "slui.exe" and hit "Enter"
2. Enter your Windows 11 Pro product key. If it's not accepted, apply the default product key like: "XXXXX-XXXXX-XXXXX-XXXXX-XXXXX"
   If error code "0x800f0805" appears after applying the default product key, please make sure that you have at least 20 GB of free disc space and that Windows is updated to it's latest version. If those two points apply to you, it is obvious that some important system files are missing. In that case it is necessary to perform a clean installation (see Option 1).
3. Go to "System" - "About" and "Change product key" (Click "Yes", if User Account Control comes up)
4. Enter your Windows 11 Pro product key and make sure all open applications are closed and your work is saved, then start the upgrade.
   Wait while the upgrade process kicks off - your computer will be restarted several times throughout this process. The amount of time the upgrade takes will vary between operating systems. But in our experience, it only takes 5 to 10 minutes.

Finally, you have to configure the Windows 11 Pro system. In this process, you decide on, for example, the sending of diagnostic data and privacy settings. Select what you think is appropriate. Don't worry - you can change these preferences any time after installation.
