The thread is about whether Windows 10/11 ISO “corruption” could be the cause when SFC (sfc /scannow) reports corrupted system files after installing a 64-bit Windows. The main answer is that a corrupted ISO is only one possibility; more common causes include a bad installation USB/media creation, disk/SSD issues, faulty RAM, or corruption in the Windows Component Store—recommended first steps are running DISM health/repair commands and then SFC, and if needed pointing DISM to the ISO’s install.wim/ install.esd as a source. Overall sentiment is helpful and troubleshooting-oriented, with participants asking for follow-up logs (SFC/CBS entries) to identify the exact files SFC can’t repair.
