* Cygwin/X and Vista and UAC

I am trying to setup Cygwin/X for a Vista machine

After setting some executables to run as administrator, and then after
cleaning up some lock files and log files, the x server and applications can
be run by a user with administrator privileges.

BUT,

1) The x startup (by any method)  throws a UAC prompt
2) A non-privileged user cannot get past the UAC prompt without the
administrator password

Perhaps some .manifest files would cure this?

Are there any other ways to allow a non-privileged user to run cygwin in
vista?

Thank you
M. C. Nelson

You shouldn't need to do this.

Isn't this the reason for your UAC prompt?

I think I understand the problem with the log file in this situation, and have 
a patch (see [1]).

But the lock files should be removed when the X server is cleanly shutdown, so 
there's some bit of information I'm missing here.

I wasn't able to reproduce this problem doing some brief testing on W7 (I 
don't have access to a Vista system right now)

There is a manifest embedded in the XWin application [2], but it doesn't do 
anything to affect UAC at the moment.

Do you have some suggestion as to what you think it should contain?

Okay, I agree we need better information.  So, I think I want to start again
with a clean install. I understand that the procedure for removing cygwin is
to just delete everything.  Does it create any registry entries that should
be deleted?

Thank you

There might be a very destructive error in the uninstall instructions:

	3. Delete the Cygwin root folder and all subfolders. ....

The subfolders include /cygdrive/c/, etc.

I suppose it's possible to try to delete everything in Cygwin with Cygwin via
'rm -rf /' but it wouldn't be a success even if your observation wasn't an
issue.  But I agree if someone tried to do just that, then this is a potential
danger.  So the FAQ could be more clear/instructive on this count.  Care to
offer a patch for the documentation?
