So, I've been playing a lot the last few days with 10, mainly deployment, imaging, and customization from a quick upgrade installed 10 Home host, which when upgraded to from 7 activated with Daz's Loader DID NOT automatically activate after install and never activated--for the best because a better way exists (as mentioned below). So far, and believe me I was very skeptical at first, this is the best Windows bar none, and I'm finally once again excited about the future of the Windows platform. What I like best: RAM is finally utilized correctly in my opinion--though the OS uses more memory than previous versions, that memory is used more wisely. Things that I would suspect to cause lag and slowdown don't, and I find the system seems to support memory intensive functions like multiple desktops very well. Aesthetics are simple, clean, and able to be customized to my likes without the need of multiple third-party software or hacks. Finally I can theme Windows like I want it right out of the box. It's about damn time, Microsoft. General usability and user friendliness is back, which was lacking in 8 altogether. No more feeling like an idiot trying to find common settings and applications. OS portability is greatly improved from 7, and now usb drives and thumb drives and vhd's can all be installed to and booted from more easily than ever before, meaning having a fully functional Windows system with all your stuff is a realized reality and not a novelty. What I dislike most: Mobile / Tablet integration into Windows core functionality. The idea of "apps" for my main computing system seems dumb to me. Why would I want any of the same similar things that I have on my Android tablet or my Android phone on my Windows computer? Usually I am wanting the functionality of my computer on my tablet or phone, not the other way around. I don't like how core features like the calculator have to be replaced by a mobile platform type of app instead of the good ole calc.exe. If one wants to use an app for such then by all means let them, but don't make it mandatory. I could say a lot more, but these are the things worth noting more than anything else. I think Windows 10 is a home run for Microsoft. I'm happy I decided to try it. I'm now running the latest Education variant of Enterprise, with all the extra crap other than the store removed with MSMG Toolkit, clean installed from Paul's X Files, and activated with the latest Microsoft Toolkit. Couldn't be easier. Thanks to MDL!!!!!!!!!!!!!!!!!!!!!!!!
