My pc is new and running on windows 10 and 16gb ram but my memory is soo high ?
Dude I don't see anything wrong on that Task Manager. Also, Windows 10 has something I hate. That task called Compressed Memory it's a feature that Windows 10 has and he just uses your RAM to hold on your cache. For 8GB systems this feature sucks! windows 7 uses the hard drive to cache your things.
In a near future, it's normal if you see that task consuming around 2GB of memory.
