bash 4.4.12-3
coreutils 8.26-2
cygutils 1.4.16-2
cygwin 2.10.0-1

Run it in bash instead.
^ is a quote character in CMD.

Hello Michel,
Thank you.
Yes, I guessed it is a special character, so I tried (did not work):
echo qwe | grep -E '[\^r]'
I have finally figured out. Using double-quotes work:
echo qwe | grep -E "[^r]"
Kind regards,
Dmitry
