I've been having this problem for a while now. Almost every day my computer's disk usage spikes up to 95-100% for about an hours or so. There are two system process responsible for this under the names of "Service Host: Local System (Network Restricted) (14)" and "System and Compressed Memory". The latter process never gave me trouble until about a week ago. When I go into Task Manager Performance and check the disk, only Read is sky high, Write is usually low. Also, "System and Compressed Memory" uses +200.0 Mb when my system is completely idle.
EDIT: New to the forums, not sure where this would go.
