I've searched the internet for this question, and I've found some answers, like this one. All answers I can find say the same thing, that it refreshes the desktop folder, in other words, the icons.
My issue with this is that I'm running a windows 7 pc, that is incredibly slow, but when I press refresh, everything stops for half a sec, then runs smoothly again, if I instantly refresh again, it refreshes directly (not the half a second delay)
Before I searched the Internet for it I thought it could be the 'todo' list of the computer resetting, so when I refresh it just resets all its planned tasks and starts on a blank slate.
Now, if my 'refresh' click only updates the icons, why does everything seem to get resolved?
If there is no answer for this, other than
it just refreshes the icons, the 'resloved' feeling is all in you head
I'd like to know if there are any good software I can use to monitor what happens when in my computer, so I can see for myself what is going on.
