I still don't understand why people aren't upgrading to Windows 10. Sure there MAY be possibilities but 10 will be supported for a long time and Microsoft would probably be more helpful/willing to help if you're using their newest pride and joy.
I'm actually confused. See i was a Windows 8.1 user when Microsoft started rolling the free update for Windows 10. When i updated the OS i noticed a clear nicer interface and it was much more attractive than before. It included new tools and modules never seen before and was really a good option. I still was not happy with its performance. On a 8GB, i5 laptop with Intel HD Integrated Graphics, it showed no interest on being as fluid as it should be, still i kept it, security was a priority for me. Now, a massive error from mine when editing and deleting partitions made me break the whole system and had to format the disk (luckily files were backed up). I'm temporaly at Windows 7 and i'm starting to re think on migrating again to Windows 10. I've experienced no lags or bugs, and my speed experience is awsome, once again. Of course, it may be due to the recent format, but still, when i migrated to Windows 10 i decided to format the disk as well, and results are different.
With my security knowledge, internet habits, and working needs, i'm starting to think again Windows 7 is my suitable choice. Maybe not the best one, but the one that combines the best with what i need.
