It’s always best to make sure you’re downloading a legit and untampered version of your operating system you want to use. Here’s a simple three step guide to download a copy of Windows 11 directly from the Microsoft website.
Step 1) Go to: https://www.microsoft.com/en-us/software-download/windows11
Step 2) Scroll down till you Download Windows 11 Disk Image (ISO), select your language, it should then simply generate you a download link that lasts for 24 hours.
Now, you could just load that onto a USB and be on your way (using rufus to create a bootable USB drive), but maybe you want to actually verify what you’ve downloaded? Here’s how:
Download IgorWare Hasher, which basically verifies the files SHA-1, MD5 and CRC32 hashes. Using that you compare it to a known list of verified ISO’s. This time Microsoft provides these hashes right after selecting your preferred language.
Oh and for your information, “English International” is the British English version, supposedly.
