Windows 11 Pro System Requirements

Before downloading, make sure your PC meets the minimum requirements:

💡 Tip from DotKeys: You can use Microsoft's PC Health Check app to verify your device is Windows 11 compatible.

Part 1: How to Download Windows 11 Pro

You have two main methods to download Windows 11 Pro. We recommend the Media Creation Tool for most users.

Method 1: Official Microsoft Media Creation Tool (Recommended)

This is the cleanest and most reliable way to get Windows 11.

Step 1: Open your browser and go to Microsoft's official download page: 👉 https://www.microsoft.com/software-download/windows11

Step 2: Under "Create Windows 11 Installation Media," click Download Now to get the Media Creation Tool.

Step 3: Run the downloaded MediaCreationTool_Win11.exe file.

Step 4: Accept the license terms.

Step 5: Choose your language, edition (Windows 11), and architecture (64-bit).

Step 6: Select the media type:

• USB flash drive – minimum 8 GB
• ISO file – for creating a DVD or virtual machine

Step 7: If you chose USB, select your drive from the list. The tool will automatically download Windows 11 and create your bootable installer.

Step 8: Once done, you'll see "The USB flash drive is ready." Click Finish.

Method 2: Direct ISO Download

If you prefer a direct ISO file (useful for technicians or virtual machines), Microsoft also provides a direct download link on the same page above. Just scroll down to "Download Windows 11 Disk Image (ISO)" and select Windows 11 as the edition.

Part 2: How to Install Windows 11 Pro

Now that you have your bootable USB or ISO, here's how to install Windows 11 Pro.

Option A: Clean Install on a New PC

Step 1: Plug the USB drive into your PC.

Step 2: Power on the PC and press the boot menu key (usually F12, F2, ESC, or DEL — it depends on your manufacturer). Set the USB as the first boot device.

Step 3: Save BIOS changes and restart. Windows Setup will launch.

Step 4: Choose your language, time format, and keyboard layout, then click Next → Install now.

Step 5: When asked for a product key, you have two choices:

• ✅ Enter your Windows 11 Pro product key (recommended — saves time later)
• ⏭️ Click "I don't have a product key" to install first and activate later

Step 6: Select Windows 11 Pro from the list of editions and click Next.

Step 7: Accept the license terms.

Step 8: Choose Custom: Install Windows only (advanced) for a clean install.

Step 9: Select the partition where you want to install Windows (you can format the drive if needed) and click Next.

Step 10: Windows will copy files and restart several times. The installation typically takes 10–20 minutes.

Step 11: Complete the Out-of-Box Experience (OBE) by connecting to Wi-Fi, signing in with your Microsoft account, and adjusting your privacy settings.

Option B: Upgrade from Windows 10

If you're currently running Windows 10 and want to upgrade:

Step 1: Make sure your Windows 10 is fully updated (Settings → Update & Security → Windows Update).

Step 2: Run the Media Creation Tool and choose to upgrade this PC now.

Step 3: Follow the on-screen prompts. Your files, apps, and most settings will be preserved.

Step 4: When asked for a product key, enter your Windows 11 Pro product key from DotKeys.

Frequently Asked Questions (FAQ)

Can I install Windows 11 Pro without a product key?

Yes. You'll get a 30-day trial period, but a watermark will appear on your desktop, and some personalization options will be locked. To remove the watermark and unlock everything, you need a valid product key.

What's the difference between Windows 11 Home and Pro?

Pro includes everything in Home plus BitLocker encryption, Remote Desktop, Hyper-V, Windows Sandbox, Group Policy Editor, and Active Directory/Azure AD support. Most business and power users need Pro.

Can I use my Windows 11 Pro key on multiple PCs?

It depends on the key type:

• OEM keys – locked to one PC (the first one activated)
• Retail keys – can be transferred to a new PC after deactivation
• Volume licenses – for businesses with multiple seats

At DotKeys, we clearly label the key type on every product page.

How do I check if Windows 11 Pro is already activated?

Go to Settings → System → Activation. If it says "Windows is activated with a digital license" or "Windows is activated with a product key," you're good.
