I have a problem that my windows 7 computer sometimes starts accessing the disk like crazy for maybe 10 minutes at a time. The process in question is the "system" process. I have disabled superfetch and hibernation on my computer, if that makes any difference. I disabled those to see if they were the cause of the problems, but no change. I have 6 GB of RAM and only the web browser was started when I took the screenshot, so I don't think it was thrashing due to page faults.
Any ideas on how to find the cause of this?
I have this same problem, but it's not updates (disabled by corporate policy). Seems to relate either to virus scanning OR corporate inventory system... System process seems to visit files on the system at random, and appears to scan through the entire file. It's a killer when it visits my mammoth PST/OST files, kills the cache, and basically brings the system to its knees... – andersoj – 2014-09-08T17:39:17.157
5You could use Process Monitor to see which files the system process is reading from and writing to. That might help you give a clue as to what it is doing. – Mr Alpha – 2011-10-22T10:23:26.927

But quite possibly I messed up the filters. I'll do another attempt the next time it happens. – Mats Ekberg – 2011-10-23T12:32:54.280
Now I've done some logging with Process Monitor. I could post a screenshot, but I don't think it would add anything. I logged all events from the System process (pid 4), no filters. I can not see any obvious intensive activity. Occasional reading/writing of a few kilobytes, but not the 10MB/s activity I can see in resmon. This is a complete mystery to me. Does anybody know of any other tools that might help? – Mats Ekberg – 2011-10-30T14:28:43.740
I have this problem but it's not IE updates. Resource monitor shows that system is visiting many, many files across the whole filesystem (some of them very large multimedia or blob files) and reading at a high rate. – andersoj – 2014-05-28T17:45:47.867
