Con Crontab and other background jobs don't work properly
Crontab only runs on ROOT, and it needs Windows to stay open. If you close it, you will kill the crontab. Some background jobs don't run on Windows WSL.
Con Does not install on PC virtual machines

Any other SSH client will render the remote server at whatever size the local client window is. The built-in SSH client on Windows, however, forces you to use a standard size, and it's small enough to cause problems.
