- Or use DISM to create an ESD: dism /Export-Image ... /Compress:recovery and then convert to ESD with DISM /Export-Image + /Compress:recovery (tools vary by Windows version).
Safe checks:
Use 7-Zip to open any suspicious ISO before burning. If sources\install.wim or install.esd is missing, the ISO will not install Windows. If you see a single .exe that “expands to ISO,” scan it with VirusTotal.com.
