How big, fast, and full is your disk? How much memory is installed/used/free in Resource Monitor? Have you a lot of services started that you don't use? Are you seeing many pageins/pageouts? How much paging space is allocated? Try allocating 2*physical memory size as paging space. If that helps, you may want to add more or faster memory if you only have 4GB installed, or most of it is used, with low free. Some people have improved performance by increasing the min free memory setting, to keep more instantly available for use. Search google or stackoverflow for W7 Pro min free memory advice. -- Take care.
