Windows 10 ISO mounting bugs
Short description: current windows 10 ltsc freezes when trying to mount an iso file, especially a windows installation image. Setup: Windows 10 IoT Enterprise LTSC 2021 x64 en-US. Clean installed from ' en-us_windows_10_iot_enterprise_ltsc_2021_x64_dvd_257ad90f.iso'. All updates have been fully done, including latest cumulative updates(KB5126657), servicing stack updates, .NET framework updates(4.8.1), and any other hardware-dependent driver updates. When I try to open and mount a windows installation image (iso), the explorer freezes, and is unresponsive. ISO files that are not Windows installation images open fine, and even when explorer is frozen, other parts of Windows work totally fine(like browsers). This behavior hasn't been seen before the 2026-10 cumulative updates. Maybe the KB5126657 has something to do with it? PC hardware: i9-10900KF, DDR4 32GB RAM, 1TB NVMe SSD, Z490 MB. I've been using this PC with the exact same OS for years, and this is the first time experiencing such issue. Tried troubleshooting with claude code and codex, but failed (mainly due to session halting by cybersecurity flags)
