Ano, ale musíš pochopitelně udělat čistou instalaci.

Nenastavis.

First, if you haven’t upgraded to Windows 10 yet, you’ll need to use the upgrade tool to upgrade. You’ll get the 32-bit version of Windows 10 if you were previously using a 32-bit version of Windows 7 or 8.1. But the upgrade process will give your PC a Windows 10 license. Be sure to check that your current 32-bit version of Windows 10 is activated under Settings > Update & security > Activation.

Once you’re already using an activated version of Windows 10, download the Windows 10 media creation tool from Microsoft. If you’re using the 32-bit version of Windows 10 at the moment, you’ll have to download and run the 32-bit tool.

Select “Create installation media for another PC” and use the tool to create a USB drive or burn a disc with Windows 10. As you click through the wizard, you’ll be asked whether you want to create 32-bit or 64-bit installation media. Select the 64-bit architecture.

Next, reboot your computer and boot from the installation media. Install Windows 10, selecting “Custom install” and overwriting your current version of Windows. When you’re asked to insert a product key, skip the process and continue. You’ll have to skip two of these prompts in total. After you reach the desktop, Windows 10 will automatically check in with Microsoft and activate itself. You’ll now be running the 64-bit edition of Windows on your PC.
