Hello. I have two (2) important questions regarding Windows 8.0 and 8.1 for Aero Glass for Windows 8: 1. Will your program to achieve Aero Glass for Windows 8 (either Windows 8.0 or 8.1) cause serious Windows file system errors? What I mean specifically is -- will your program patch(es) (a) dll file(s) to run non-MS Visual Styles incorporated on my system? Ultimately, when Windows System Configuration Utility manually runs (sfc /scannow), will it report Windows file system errors in Windows 8.0 or 8.1 typically reported with other third party venders programs who modify MS Visual Styles files? 2. As of date, you are still developing the Aero Glass for Windows 8.1 on its own merit as I can tell from your website. My question, observing you are independent on programming for each version of Windows 8, are you planning to have separate licensures (payable through your PayPal donation) for each version of Windows 8.0 and 8.1 Aero Glass for Windows or not? In other words, if I get a licensure right now for Aero Glass for Windows 8.0, will that same licensure also work for Aero Glass for Windows 8.1 or not? Since Microsoft sees Windows 8.1 as a free update through Windows Store from Windows 8.0, will you align your licensure business model in the same manner as free update too with your product or not? Please explain. Please reply. Thank you very much!
