Windows 10: Totally confused! Everything is slow!

I am running windows 10 on an older machine. All browsers are super slow and lag all the time regardless of internet connection speed. A lot of my programs lag as well and if they connect to the internet they often have connectivity issues. What one earth is going on? Only games I've been able to get to function half way normal is age empires 1 and 2 but even that has issues. The game changes the cursor and the damn thing always blinks and more than half the time can't be seen. Help! This is beyond me!

I am starting to think windows 10 is straight garbage and will never work. Probably shift to XP! Can't stand 7, don't like 8 and apparently windows 10 is broken.

It would be a mighty big help if you'd fill in "My System Specs" below left so we volunteers could get some idea of what your performance should be like. Very difficult to diagnose or suggest solutions otherwise. Myself, I like Win10, have the RTM version running on 2 Desktops and several Notebooks along with Insider Preview on 2 Desktops. Also have a Win7 Desktop running but only for the occasion a client has a question.
