There is no such thing as running out of memory that is what the HDD or SSD is for, page file.
Next time this happens, simply close every program, and without restarting see if the memory has been released, when you restart your browser (not restart your computer).
Post what happens, then we can go on from there.
Actually every new version of Windows has made improvements over how memory is handled. People have misunderstood memory allocation on newer Windows versions, and have incorrectly assumed that newer Windows are memory hogs. They are not. The problems you are having are unique to you. I hope they can be fixed.
You don't have to use any program for icons, I was just sharing how I go a step further and want every icon to be in a custom place so that if those places are re-arranged, that program restores them. You don't have to do that, absolutely not...
I do heavy modding of Android cell phones and never in my life have I found worse examples of frustration than on Android.
Are you kidding? Are you aware how many new restrictions EACH new version of Android has brought?
Android is EXPONENTIALLY WORSE than Microsoft Windows when it comes to freedom to choose what you want.
I can engage you on this in detail, I have custom Android operating systems on all my cell phones, I routinely install the newest Android versions on older cell phones and see first hand how many new restrictions they put in place.
Your problems are not experienced by everyone therefore they cannot be blanket applied to the Windows operating system, wingman99.
But we can maybe figure them out and fix them...
