I purchased Start8 and love it. I want to test drive Windows 10 but don't want to use it without Start10. I would be happy to pay $5 or whatever you decide to charge for a license before the final release. I understand you're trying to drive customers to your other products and subscription model, however, I only use and want Start8 and Fences, which is why I purchased them separately. I hope you reconsider this decision as I would like to begin using Windows 10 with Start10 now so I can begin, otherwise I will have to wait until release date.
Thank you for your time,
