1. I don´t like -admins and .c02/.cli, can I change it?
Sure. Just edit the scripts (.ps1 and .xaml) and replace the endings with your desired ones.
2. Where do I change the entries in the dropdown menues?
Edit the .\Xaml\12beAdmin.xaml
3. Why are you only using „!“,“+“,“-„,“@“ as special characters?
This is because of the big amount of different languages and keyboard layouts. This 4 special characters are usally well known on the keyboards. Keep it simple. The password is long, it´s complex and it will be only valid for a short period of time. It is secure (enough).
4. Does the Password length meet my Password Policy?
Yes, 12beAdmin reads the length from Default Domain Policy and definies it as the minimum length. It does not consider Password settings objects. You can manually edit the $MinLen inside 12beAdmin.ps1
5. Install RSAT fails with 0x800f0954
Set Policy Computer Configuration\Administrative Templates\System „Specify settings for optional component installation and component repair“ to Enabled and activate/check „Download repair content and optional features directly from Windows Updates instead of Windows Server Updates Services (WSUS)“
