Upgrade Windows 10 Home to Windows 10 Professional

To upgrade Windows 10 Home to the Windows 10 Professional edition, you need a Windows Professional Retail Key. In particular, a Windows 10 Professional Upgrade Key.

Step 1: Preparation

1. Install all pending Windows updates.

2. Temporarily turn off or pause your antivirus software.

Step 2: Verify Account Rights and Type

1. Click the Start menu (Windows icon) and click Settings (gear icon).

2. Click Accounts.

3. Under Your info, verify two things:

   • Look for the word Administrator under your name.

   • Ensure the login shows an email address (indicating it is a Microsoft account) and not just a local username.

Note: If you do not see "Administrator," you must log in as an administrator. If you see a local username instead of an email address, click Sign in with a Microsoft account instead on this same page and follow the prompts to link or create a free Microsoft account.

It is possible that an error is displayed. Please use the troubleshooting function and restart your computer. If you wish, you can remove the Microsoft account from your computer after the upgrade.
