Tutorial Windows: How to Upgrade from Windows 10 Home 1511 to Pro Version

If you’re one of those users who want more control over Windows updates and also need features that are bundled into the Pro SKU, then you obviously want to move from Home to Pro in an easy manner, without losing any of your data.

Luckily, Microsoft does provide a way to upgrade from Home to Pro without the need for a clean reinstall. And what’s more, the whole process doesn’t cost anything, but you’re still going to need a Pro key to validate your install.

Keep in mind that this method only works if your Windows 10 Home PC is already running the November Update (version 1511). To check the version number currently running on your computer, click the Start menu, type “cmd” and enter the following command:
