Rufus developers blame Microsoft for blocking access to the latest Windows 11 ISOs — WindowsInsiders met with an IP ban after attempting to download latest builds

Source: Tom’s Hardware

Issue Overview

A recent change to Microsoft’s Windows 11 downloads is reportedly stopping some users and third‑party sources from downloading Windows 11 ISOs from its servers. Originally reported by Neowin, multiple Windows Insider users say they are unable to download Microsoft’s latest Insider ISOs. The team behind Rufus confirmed the same problem, stating that Rufus cannot install the latest Windows 11 Insider Preview ISOs.

Cause

The download issues do not appear to be bugs or glitches. All of the Windows Insiders who have complained say they can’t download the latest Insider ISOs because Microsoft is blocking their IP addresses. The problem is occurring across multiple ISPs and even when using VPNs, confirming that it is not an ISP‑specific issue.
