I currently have Windows running on a PC. I have just purchased my first Mac. Unfortunately they stop supporting Windows 7 installations but do support Windows 10. I'm not sure how an upgrade works for this situation. Win. 7 was preinstalled on my PC when I bought it. If I do the upgrade to vs.10 will I be able to copy it to a thumb drive and go through the MAC insstall that does support vs.10 or will I be copying vs.7 and a vs.10 update? Or, if I update to Win 10 on the PC can I request a download of Win. 10 with my Windows ID #. How would I go about asking for the Vs Windows 10 to put on a thumb drive to install on the Macbook Pro? They did sent me a requested Win 7 disk but that isn't going to do me anything for a Mac install.
