DMG Extractor and 7-Zip will allow you to open Mac's DMG file format on Windows 11/10 PC easily. Read reviews and download free.

Windows is frustrating, nuff said. How does an Apple Disk Image file, aka .DMG, not being able to open natively on Windows make Windows frustrating?

On Windows, HFS+ can be read only with the aid of software such as MacDrive or MacOpener; it's possible to run MacOS 8.1 in emulation, but I know of no suitably old software that can open .dmg ...

If it opens a DMG it cannot handle (such as an installer), it will simply open the folder. Great, start stuff that saves you time and frustration.
