Hello. I've done my research but I'm finding conflicting information everywhere and things have changed since the win 10 launch so I guess I better ask here for an updated insight, not only for me since I've noticed a lot of people try this route. I have Win 7 Ultimate 64 activated with a Bios mod and slic 2.1 in SSD1, SSD1 is old and I'm upgrading to a new one. In the new SSD2 I'm planning with going with Win7 again but I don't want to lose the chance to upgrade to 10 when all the bugs and tracking are finally ironed out. My plan is to install 7 in the SSD2, update it and clone it to another disk (SSD1) so I can update that copy of 7 to 10 while keeping the original 7 in SSD2 activated. I'm planning to dualbooting with the bios boot tools. The question is simple: After activating that clone of 7 upgraded to 10 would I be able to keep my original 7 activation and drive intact? I read somewhere that this is against the EULA so maybe MS will try to screw this type of cheat later. Another question kind of related: Would you say that I can let go the MS free offering and find a (bulletproof) way to activate Win10 later on like we do for 7? thanks for your insight.
