What is the best windows 11 upgrade assistant from windows 10?

Yes, Microsoft offers a free Windows 11 upgrade assistant app called the PC Health Check app, which helps determine if your PC meets the requirements for Windows 11. Additionally, you can use the Windows 11 Installation Assistant, which is designed to upgrade compatible devices from Windows 10 to Windows 11.

What are your options?
1.Use the PC Health Check Tool
Download it from the Microsoft website and see if your PC is officially compatible.
(Note: As of recent updates, Microsoft has re-released and improved this tool.)

2.Attempt to upgrade manually
Some users bypass the hardware checks using unofficial methods, but this is not recommended because it can lead to stability issues or security risks.

3.Consider staying on Windows 10 until you're ready to upgrade hardware or choose a compatible device.
Microsoft will support Windows 10 until October 14, 2025, so you still have time.

For your HP Z230 with an i7-4790, the best and safest "Windows 11 upgrade assistant" is not an automatic tool, but a manual process using the official Microsoft Media Creation Tool and performing a clean install.
