Cygwin
Ranked 6 of 27 compatibility layers by recommenders
Gives Windows bash, grep and other Unix tools that run natively, and many users find it reliable. The common caveats are DLL hell, slowness and hacky emulation.

What people warn about
Each mark is one comment
Hacky emulation that slows programs
“contains a lot of complex inefficient hacks to do things which Microsoft could do much more easily”
Comment from 19 Jan 2026 in “Prediction: Microsoft Is Going to Do the Funniest Thing Imaginable” “Cygwin is a crazy approach, was slow (contrary to the implication of the "low cruft" claim)”
Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux” “Cygwin does many unholy things to enable signals and fork syscall in binaries.”
Comment from 2 Jun 2026 in “Coreutils for Windows” - Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux”
- Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux”
DLL hell and dependency problems
“that cygwin1.dll (plus any dependencies) is a problem for distribution.”
Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux” “The problem with Cygwin as I remember it was DLL hell.”
Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux” Outdated packages and manual updates
“Cygwin was also notorious for being really out of date. Security vulnerabilities and missing features were both very common at one point.”
Comment from 23 Apr 2026 in “Windows 9x Subsystem for Linux” “needs to cleanly coexist side-by-side with existing Cygwin installations and optionally support silent install/upgrade/uninstall”
Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux” “Cygwin still lacks that to this day, you have to fire up to GUI installer to update packages.”
Comment from 22 Apr 2026 in “Windows 9x Subsystem for Linux” Linux apps need recompiling for it
“Requiring every single Linux app developer to recompile their app using Cygwin and account for quirks that it may have is not the correct approach.”
