I notice that on my Gateway computer (Pentium 4 Dual Core XP Media Center Edition 2005 with sp2) "explorer.exe" is using 60,000k+ memory usage. I have 1024 system memory, so I am not having memory shortage problems, nor do I get "explorer" errors .I am just curious why "explorer.exe" is using so much memory. It does not appear to be a memory "leak" problem because when I reboot the computer it starts up right where it was and stays between 60,000 and 70,000 no matter how many days the computer stays on, or what programs are running. Yet when I log out and switch users in XP, the other users set up on same computer have "explorer.exe" using about 13,000 to 20,000k maximum. Each user has the exact same "processes" running.I have done a virus scan, a couple different spyware scans plus I do regular defrags. No problems found and this has not made a difference. I also did the registry fix for "avi" files that I saw mentioned as a possible solution while "googling". Any help/suggestion would be appreciated. Thanks

Explorer.exe Process Uses Many CPU Cycles When Windows Is Idle http://support.microsoft.com/?kbid=317751 http://support.microsoft.com/?scid=kb;EN-US;q317751

Thanks for the links, but I have already seen them. I have the latest service pack/updates from Microsoft, plus the task manager shows my "explorer.exe" normally uses 0 cpu when idle, it is the memory usage that is 60,000k+.

If it takes too much memory follow this: 1. Go to control panel then performance and maintenance and go to system. From there go to advanced settings and go to performance again. 2. Access virtual memory settings. Since you have a noble amount of RAM you can boost up virtual memory. Windows also determines how much page file memory you should have by clicking "system managed size". You should at least have a gig of virtual memory. Also note that virtual memory takes up disc space. Make sure you have a lot of that as well. This is good if you want to start up bigger programs like games or start multiple programs in one. Am I smart? How the hell am I supposed to know and if you were smart you wouldn't be asking such stupid questions. -Mort from Trip to Appleblossom City.

Thanks for the suggestion. My virtual memory is already set at 1542mb and I just looked at explorer.exe and its memory usage is 66000k+ and virtual memory is 62000k+. That's seems like a lot of memory usage to me. Luckily I am getting no error messages, nor any errors in windows "Event Viewer".
