    I wasted a couple of hours when working with Windows 11 Installation Assistant. If the problem was not fixed or you are looking for an alternative way to install Windows 11, go and try this method instead:

When the Windows 11 Installation Assistant seems to take an extremely long time or appears stuck during installation, there are several possible reasons and troubleshooting steps you can take if Windows 11 Installation Assistant not working and takin forever. Please take a full read of the following suggestions.

Pre-Installation Checks

Ensure Your System Meets Requirements: If your hardware is on the unsupported list, additional steps (like registry tweaks) might be needed to bypass checks. Unsupported hardware can sometimes lead to unexpected delays or issues.

Update Your Windows 10: Make sure your current operating system is fully updated. Pending updates can interfere with the upgrade process.

Sufficient Disk Space: Verify that you have enough free disk space. Windows 11 requires a significant amount of space for installation.

During Installation

The installation process may appear to be stuck even if it’s working in the background. In some cases, especially on slower systems or those with limited resources, operations like file copying and configuration might take a long time.

Also unplug USB devices or other peripherals that might interfere with the process.

Troubleshooting Steps

Run a Clean Boot: Boot into a minimal state (clean boot) to reduce software conflicts. This can help isolate if background services are delaying the installation.

Temporarily Disable Antivirus/Firewall: Sometimes security software can interfere with installation progress. Disable these temporarily (ensuring you're in a secure network environment) and then try again.

Check for Logs/Errors: Look for any error messages or logs that might indicate what’s causing the delay. These logs can often be found in the Windows Setup logs or by checking the Event Viewer.

These are very useful tips to fix Windows 11 installation assistant not working for clean install!
