suggestion for Cygwin FAQ 2.19 "How do I uninstall all of Cygwin?"

[Tom Schutter]

I was attempting to uninstall all of Cygwin when I ran into a snag.  I
couldn't delete bin/cyglsa/cyglsa.dll because it was referenced by
LSASS.  I was able to fix the problem by restoring the
/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Lsa/Authentication
Packages registry entry back to it's default value of msv1_0,
rebooting, and then removing cyglsa.dll.

But the point of this email is that I think this step should be added
to the Cygwin FAQ 2.19 "How do I uninstall all of Cygwin?".

you're right.  Would you like to provide a patch to faq.xml?


Thanks,

I sent this email to the patches list (which I am subscribed to), but it
doesn't appear to have gotten there.  At least it does not appear in the
archive.

I don't know why this occured, but it doesn't matter for this patch.
Can you please resend it as unified diff `diff -u', though?  From the
below "normal"-style patch it's not clear where exactly the new listitem
was supposed to go, especially because the line numbers don't match
after my faq-setup.xml changes from yesterday :}


Thanks a lot,
Corinna

I don't see any indication of email from you to cygwin-patches in
the logs.  I see what appear to b two attempts to accept a subscription
but no actual email to the mailing list.

The second attempt was to make sure that I wasn't imagining the first
attempt.  And then I got a message that said I was already subscribed. 

At Tue, 12 Nov 2013 12:36:57 -0700 I sent the unified diff to the
patches list, but it again does not appear to have gotten there.
Puzzling.  I was able to send it to the main cygwin list.

I don't have a problem because my patch got there by another means, but
if this is an indicator of a problem for others, whatever I can do to
help diagnose...
