- Alternatively, go to Settings → System → Activation → Change product key, click Yes at the UAC prompt, and enter your key

Search for cmd in the Start Menu, right-click it, and select "Run as administrator".
Step 2: Check Upgrade Eligibility
Paste the following two commands one at a time, pressing Enter after each:

Frequently Asked Questions (FAQ)
Is Windows 11 Pro free to upgrade from Windows 10 Pro?
If you are running a genuine, activated copy of Windows 10 Pro, you can upgrade to Windows 11 Pro for free via Windows Update (subject to hardware compatibility). However, if you are starting fresh or need a new licence, you will need a valid product key.
What is the difference between Windows 11 Home and Windows 11 Pro?
Windows 11 Pro includes all Home features plus BitLocker encryption, Remote Desktop, Hyper-V, Windows Sandbox, domain join, Group Policy management, and Azure Active Directory support. For most home users, Home is sufficient — but Pro is essential for business, developers, and power users.
Can I use Windows 11 Pro without a product key?
You can install and use Windows 11 Pro without activating it, but you will see an activation watermark on the desktop and be unable to personalise your system (change wallpaper, colours, etc.). Purchasing a genuine key from Softkeyworld unlocks the full experience at a fraction of the retail price.
Will my files be deleted during a clean install?
Yes. A clean installation wipes the selected partition. Always back up your important files before proceeding. If you upgrade in-place (Option 2 or 3 above), your files and apps are preserved.
How many PCs can I use one Windows 11 Pro key on?
A standard retail licence key is valid for one PC. If you need to install on multiple machines, you will need a separate key for each device.
