Please include exact and complete version of Ruby you're using (ruby -
v) and under which Windows flavor.

Also, if this can be reproducible with any COM object, include a
sample script for us to reproduce in other Windows version and Ruby
version combinations.

Once we have that and we can confirm, I'll recommend submitting a bug
report to Ruby own bug tracking system:

http://redmine.ruby-lang.org/

There select the proper version and report the issue.
