I have just found a new thing on windows 7: everytime I go idle for lets say at least 10mins(where the power saving mechanism kicks in), and after a couple of mins after that, my pc led light thingy flashes quickly as if it were processing something. Then after I came back, to my surprise, my drive c space got occupied a little. From 94GB to 93.5. I don't know why this happens, is this a windows 7 thing? I scanned with avira and mbam and found nothing. So should I be worried? Can someone explain this?
EDIT:
So I just also noticed that after one week, the space gets back, but when I go idle again, it eats it up again. So someone care to explain what this is? Is this windows 7 innate?
