This is not helpful. Cygwin setup-x86-64.exe not being able to update,
because SOMETHING is locking cygwin1.dll is in the top 50 of your IT
support, right followed by the question of IT support whether
"updating to WSL" will solve the situation for them permanently.

working, and that makes me unhappy because your work is GREAT

can handle those cases too.
