If you are not familiar with Windows' right management and maybe the difference between the different Windows versions (e.g. Win 10 Home has no by default visible admin), please learn about this. In case you are logged in as admin (meaning you user has admin privileges) then of course you are not asked for admin permissions since you have them already.
This is not bogus, it demonstrate you how Windows works. Have you ever tried it?as in your bogus example of cmd.exe
You should understand:I don't think you understand this from a user's perspective rather than a developer or administrator.
- the installer's default is to install only for the current user
- you opted to install purposely to install for all users
- to change something for all users, you need admin permissions and when you are not already admin, the installer will request admin permissions from you
- you obviously gave the installer admin permissions
- all you do from a program granted admin permissions, well, acts as admin, also starting a program from within it.
If you are not comfortable with this, then please don't act as admin. The default is for good reason only to install for the current user. And your case demonstrates that not every user knows what it means to act as admin.
