These iso files contain Windows Home & Pro (straight from Microsoft downloads)
You can choose between standard or the cleaned version without all the junk (like Windows7 / XP).
Nothing is added, the standard version is just 100% the same as Microsoft.
the cleaned version has all the junk uninstalled from the ESD image with standard MS commands.

The images contain:

Home - standard MS
Home - cleaned
Pro  - standard MS
Pro  - cleaned

The advantage this way is when you create a new user, the new user is also clear of any junk.

Windows11 Pro offline account:

You can install Win11Pro without a MS account using an offline account 
I disabled the network check in the image, by default iprelease or without network connection you can't install Windows 11.

Workaround:
During the install, when asked for the MS account, press Shift F10, a Command Prompt Window opens, then press 'x' <enter> to continue. (=iprelease)
Now you can fill in the offline account name, after that the network re-enables.

Bypass-TPM version is used for older HW or to install on VMware as a VM.
