This is expected. And the script outright warns you.

Contrary to *NIX, Windows runs from granular permissions system, and a user
may have the rights to install service even if they are not a member of
Administrators group.

You expect Windows to be Linux/UNIX, but it is not.
It has its own, much more usable permission system, and no God User as a
concept.

Even if it is, your current session may not have the permissions and would
require an elevation. YOU should know.

"Home PC" is a marketing joke.

How could it know?

Sure, if it's such a simple task for you - go ahead. Keep in mind that it must
remain a single binary a user can just download and run.

Cygwin setup does work exactly the same way - you just click "next" until you
get a working system.
Would that system be able to solve YOUR SPECIFIC problem, remains to be seen.

As advised, you should have stopped all Cygwin processes before attempting an
upgrade.

You're more than welcome to submit and maintain such tools.

That's VirtualBox does, not X, or Windows…

If you break your ld-linux.so, *NIX do the same.

Hardly. A lot of expectations (to put it mildly) from a volunteer-maintained
project.

You could have done so without wasting our time with this message.
