Not knowing what you did exactly, this may be the best solution.
Reinstall just the "cygwin" package.  Afterwards copy the release
DLL /usr/bin/cygwin1.dll somewhere safe.  Copy only the snapshot
DLL cygwin1.dll over the release cygwin1.dll in Windows Explorer.
Make sure the new DLL has execute permissions.  That should be all.
