You can download and install Windows 10 or 11 directly from Microsoft website. This is the safer way to install Windows since downloads from third party websites could contain malwares and other types of viruses.
There are several ways to install Windows 10 or 11...
1. Upgrade from Windows 10 (Including previous versions) or previous version of Windows 11.
2. Create a bootable Flash Drive to install Windows.
3. Download the ISO file and burn it to a DVD or keep it for future use.
What if I don't have my Windows license (Serial Number)?
Upgrading from older version of Windows 10 or 11 would automatically copy the license to the new installation.
Most of newer laptops from major OEMs would have Windows activated since the license is attached to the motherboard.
