How to update from windows 8 to windows 10?

Stick with the boring method. Your computer will thank you. The unusual methods are best left as thought experiments for system administrators on a rainy day.

Some users have reported that installing Windows 10 and entering a valid Windows 8/8.1 product key during activation can trigger a free upgrade from Windows 8.1 to Windows 10. Some community-created ISOs claim to bypass the upgrade process, but these are risky, potentially contain malware, personally, I don't recommend doing this.

 * Download Windows 10 ISO from official sources (which might be challenging without the Media Creation Tool).
 * Use a third-party ISO downloader or torrent (not recommended for legal reasons).
 * During installation, choose 'I have a product key' and enter your Windows 8 key.
 * Complete installation; Windows 10 may activate automatically if the key is valid.

To update from Windows 8.1 to Windows 10. While some obscure methods exist, they carry risks and uncertainties. The safest, most reliable, and legal way is to use official tools, you can consider downloading the ISO via direct links or using a different computer to download it and create a bootable USB using third-party tools. This approach is safer and more reliable.

You can bypasses the standard Windows 10 installer (setup.exe) and uses a more powerful, low-level deployment tool to apply the Windows 10 image directly over your Windows 8 installation. It's like performing a heart transplant on your operating system.

Instead of letting the installer do its job, you manually use the Deployment Imaging Service and Management (DISM) command-line tool to apply the Windows 10 system image file (install.wim) to your running operating system. This attempts to replace the core OS files while theoretically preserving your data, settings, and applications.

dism.exe /Apply-Image /ImageFile:C:\WIM\install.wim /Index:1 /ApplyDir:C:\

The boot sector and configuration will be wrong. You'd need to use the bcdboot command to recreate them:

bcdboot C:\Windows /s C:

Reboot your computer to start updating Windows 8.1 to Windows 10. If the stars align, it might boot into a weird hybrid state and attempt to finalize the setup, re-detecting all your hardware and installing drivers. More likely, it will fail to boot, requiring a full, clean reinstall.

The "Virtual Seance" upgrade using a Windows 8 VM checkpoint. This method uses virtualization as a "time machine" and testing ground to perform the upgrade in a simulated, risk-free environment before attempting a dark ritual to bring the result back to the physical hardware.

You treat your physical Windows 8 machine as a template. You convert it into a virtual machine, perform the upgrade inside the VM where it's safe, and then use specialized tools to try and "restore" that upgraded virtual disk image back onto your physical hardware.

This is one of the best way for updating from Windows 8 to Windows 10. However, it is a bit complicated and time consuming!

Some users report that the upgrade prompt appears if you use the official Media Creation Tool, even without a formal offer. An in-place upgrade preserves your files, settings, and apps but may carry over some issues. Please check compatibility if you are going to upgrade from Windows 8.1 to Windows 10.
