Hm, sorry, I cannot help.

I can only say that I am quite happy that I decided so far not to switch yet to Windows 10 on my Win box. I would still be able to use Perl 6 on another system, but, for various reasons, it is right now much more convenient for me to use Perl 6 on Windows. So thank you for the information, I'll postpone any Win "upgrade" for the time being, as experimenting with Perl 6 is my favorite "off-work" activity these days.

Sorry if this does not help.
