What type of PC and network do you have?
I've been using Cygwin since Windows XP days, and while it isn't as
fast as a native linux port, it IS running on top of windows.
You didn't say -- are you running your Xwindows remotely
or locally?
For me, I run the server locally, but many of the programs I
run are on linux.

Too late, it was released over a decade ago. It's maintained by
volunteers. You seem to have very high expectations of a *free product*.
Today, even most paid products wouldn't meed up with your standards.

Maybe you aren't familiar with 'X'. X is just a graphical
transport. It doesn't have menus unless some other program puts them up.
Try 'X' on linux -- running it from startX from a console and see
how easy it is to use.

Did you look in the start menu as you would with any other
application running on windows? Go look at the "Cygwin" or "Cygwin-X"
folders. The cygwin folder has all the documentation pointers you seem
to have missed, and the cygwin-X folder looks like it starts up the
desktop of your choice -- without you having to type in anything.
There's also a link for starting up the XWin Server

I always start mine in multi-window mode so the windows
intermix with normal windows, so I don't see that problem.

Cygwin repackages open-source packages. Specific program
features and suggestions should be addressed to those maintaining
those packages OUTSIDE of the Cygwin project. The Cygwin maintainers
focus on porting those existing packages so they work on windows.

So it's not just Cygwin. Maybe your graphics card is slow?
What is your DISPLAY set to?
localhost:0? or similar?

Cygwin uses the same network as all programs in windows.
It doesn't re-implement the network stack -- If it is slow, it's
likely because it is slow in windows.

How? How many ways should it try to analyze the situation?
MS doesn't document many of their interfaces. It is not always easy
to figure out why something doesn't work -- EVEN microsoft can't
figure out things. I submitted problems on Windows 7 about starting my
event log. No one at MS monitoring the user or tech forums were able
to fix it -- it happens to multiple people. The only fix MS suggest now,
is to upgrade to Win10. IF MS doesn't understand how their OS works, how
do you expect anyone else to?

It's a microsoft feature -- complain to them. Cygwin cannot
overcome all the problems in windows.

Actually windows does.

THAT's part of your problem. Several things won't work
correctly in windows if you don't have a password set. If you don't
know how windows works, PLEASE don't expect to install a program on
Windows and it to solve every problem that the underlying OS has.
If you don't know who or what your administrator account in windows
is, you are going to have a hard time installing most programs.
Cygwin provides a unix/linux type environment. But it sounds like you
have no familiarity with linux or unix or windows. Cygwin
isn't for you. It's for people who want to run free software that
is user-written and supported, for *free*. It doesn't have support.
It isn't known for being user-friendly, but neither is most software
these days.
You might be happier buying an apple computer. I don't know
about now, but they tend to provide everything you need including a
virtual companion to hold your hand getting things to work.

Nope. Gtk and Qt don't easily run on Windows -- there are ports
and there are the versions that run in cygwin, but those versions require
that cygwin already be installed, creating a catch22 problem.

Whatever the default selection is when you start setup --
usually the BASE packages.

It can. Problem is it only downloads what you are installing
and even then, what you installed may be updated and need to be downloaded
again.

This sounds like a disk corruption problem. What version of

Windows doesn't. Where do you get your expectations?

It absolutely does this. The default on Unix was to say
nothing unless there was an error. Most unix programs say very little
unless you ask them to. Do you have any specific examples? Many of
the binaries on cygwin come from the exact same source as is on linux.
(there really isn't any unix anymore)...
> I hope this all helps.

Not really. You seem to be thinking cygwin should provide
support. They have enough problems getting all the packages to
run. If you want to provide improvements, please do. But expecting
them to when they can't even support a soft-mount on MS, because they
turned it into a duplicate softlink function, is really a bit too much.

You'll be happier, believe me. It's not for you. Try getting an
Macintosh -- it's more likely to provide all the comforts you are seeking.
Cheers --- and BTW, I don't work on cygwin, I merely complain about it, er,
I mean use it (and have for over a decade).
