How could I avoid such messages (saying something like not enough RAM, close programs to avoid data loss, Win will close some programs). Explorer is shown to be closed, but I didn't open it):

My system:

Task Manager shows the Explorer with high memory use:



Obviously this message appears while I am unzipping archives.

Windows then just closes programs or crashes or what ever one might call that becavior (it sometimes logs me off and immediately on, etc.), the display flickers, etc.

Task Manager shows about 30 % of RAM being free. Why is it not enough?

I do not have opened "Explorer", so why does the message say to close Explorer?

There often are further messages when the first message appears of other programs like: "Out of memory".

My settings for the virtual memory before (set managed by Win):

My settings now to try to solve the problem (without success):

Windows 10 Version 6.2 (Build 9200) Home, 64bit
Acer Aspire E 15 (Acer E5-573)

How could I make the system work properly?
