After installing Magento 2 in Windows under Xampp, if your admin and front end link’s are not working, please follow the below steps to fix the same…

1. Open up app/etc/di.xml in the editor
2. Find the path “Magento\Framework\App\View\Asset\MaterializationStrategy\Symlink” and replace to “Magento\Framework\App\View\Asset\MaterializationStrategy\Copy”
3. Clear Cache

That’s it.

Thank You !!
