Where can I get information on "shortcuts"?

Question

Windows

Good afternoon.
Tell me where to find information about all sorts of printui, regedit , etc.
There may be some manual on the web.
I just don't know how to ask a query in a search engine.
You need something like a guide to these "short addresses".
Every time I open, for example, Add or Remove Programs via Start, etc.
It's not a problem to find a "short entry" to Add/Remove Programs on the Internet. "Just where do they get this information about these "shortcuts"?

Answer 1

These are not shortcuts. These are just the names of specific executable files.
Just like dota2.exe, there is regedit.exe or printui.exe somewhere
in the system settings. directories listed in the PATH files lalala.exe, lalala.com, lalala.bat, lalala.cmd, and only then it will give an error if not found.
In other words, if you installed dota2 to c:\games\dota and your executable is c:\games\dota\dota2.exe, then you need to add c:\games\dota to PATH and a new "short command" will appear "-dota2

Answer 2

Every time I open for example Add or Remove Programs via Start

Open through "Search". Precisely because many people did this, Windows 8 did not start to do "Start".

Answer 3

There is no directory. As the developers intended, this is how it works. Perhaps the microsoftware has a reference book, but I have not seen it. All such things are in different places, someone needed it, unearthed it himself or asked in support or somewhere else, published it. The other one can already find it at the first one, and so on.
Often you have to spend a lot of time googling and understanding the topic in search of the necessary information. It doesn't happen otherwise.
There are a few commonly used features that are quickly found, the rest ... you need to make an effort.

cmd.readthedocs.io/environment-variable.html

%PATH% Specifies the search path for executable files.
