If anyone wants a hassle free, efficiency computer running at optimum level experience, listen. I've owned many, many computers running Vista, 7, 8 and 8.1 and compared to Windows 10 this has lead me to believe two thing, avoid windows 10, and everyone else is either lying or lacking in experience of how a windows 10 operating system should function' using at least an average cpu and ram installed on there computer.
For the topic of Vista, since USAFRet question marked it. Obviously it was released back in late 2007, I won't deny it is a hogging resource software ( but that downfall only applys if your using a weak cpu, low ram )
Ultimatley after having countless conversations or disagreements with people the end explanation is the majority of people that was using Vista used cheap computers which left them with a bad experience, they can't be convinced it was a better OS over XP because only personal experience with convince them that.
I'm not going to continue this conversation, if your reading this avoid windows 10 please for your own good, prehaps if your spending three thousand dollas on a new computer you may not notice windows 10 restricting the efficiency of your cpu working at maximum ability, but for anyone else out there reading this, use caution obtaining a windows 10 laptop / desktop it will be slow the frustration it will cause is colossal.
The good news is if the computer is running a intel cpu you can install and run windows 7, 8 or 8.1
just fine, and you'll get a better, smoother, hassle free as well as a spyware free experience, have fun people.
