As the title suggests, I have a question about the "Explorer.exe" process: When Windows starts, "Explorer.exe" is automatically started as part of the GUI. Perfectly normal. When I open Windows Explorer to browse my drives, another copy of "Explorer.exe" is loaded into memory. Again, normal. What seems abnormal to me is, over time, as I continue to open and close Windows Explorer and browse my drives, multiple instances of "Explorer.exe" remain running in memory, chewing up RAM until I forcibly close them with Task Manager. I counted 4 instances running at once, when I last closed them. I've gone down my usual checklist of virus, trojan, worm, rootkit, spyware, and malware scans. All were clean. Not having used Vista, and being new to Windows 7, is there something I am missing here? Is it normal for multiple instances of "Explorer.exe" to remain running even when all programs are closed and no file browsing windows are open? Ideas/Comments welcomed. --DKnight EDIT: Currently running the x64 edition of Win7 Ultimate, just FYI.
