I have a Vista computer. When I log onto a limited account (but not the admin account) explorer will have a memory leak. It will increase rapidly till it takes up about 2,000,000 kb of memory, at which point my computer will dump the physical memory and crash. I do not know what is causing it, or why it does not happen to the admin account. Starting in safe mode does not prevent the memory leak, but if I turn off explorer and run everything using cmd or taskmgr, then the computer runs normally.
