I Cannot Update Windows when Cygwin is Running

Problem: Windows updates hang.

Cause: You have Cygwin processes running (such as bash or ssh) while you are trying to install Windows updates. The Cygwin processes take up all of the CPU usage.

Solution:
  1. Stop all running Cygwin processes, including any Cygwin services, using the Windows Services utility.
  2. Install the Windows updates.
  3. After the installation is complete, restart any Cygwin services that you might have stopped in the first step.
