Changing the configuration file may lead to issues! You shouldn't modify this file unless you really know what you're doing.
settings.inifile, which gets created on startup.
DismPath: default=null - specify a custom path to DISM (the directory must include "dismapi.dll", "dism.exe" and their dependencies) [this can be useful if the default version fails to service the image for any reason]
MinDiskSizeCompression: default=7 - minimum disk size (GB) required for a compressed installation
MinDiskSizeFullInstall: default=14 - minimum disk size (GB) required for a normal (non-compressed) installation
SkipEditionBuildNumCheck: default=0 - bypass minimum Windows build number enforcement (19041 on RPi 4 and 18362 on RPi 3) [issue reports with this flag set will be ignored!]
This config will allow a device of any size:
[WoR Configuration File] MinDiskSizeCompression=0 MinDiskSizeFullInstall=0
Note: the setup will fail if the Windows image takes more space than available.
