A good idea is to execute
CODE
puts ENV['OS']

For Windows systems, the output would be Windows_NT.

However this will return you an empty string for Linux. For further probing, you can use the following line,
CODE
puts RUBY_PLATFORM

which will give you the output i386-mswin32 for x86 Windows machines. Linux systems will output "linux" instead of "mswin32" in this case.
