There are multiple instances of explorer.exe running in task manager (currently 7), each one using between 10-40MB of memory.

Different explorer.exe processes are using cpu resources at different times.  I remember reading a while back that this could be a sign of a virus, but I've done a full scan with NIS 2010 and nothing showed up.  Can anyone give me pointers where to start investigating?

I did a clean install of Windows 7 last Friday -formatted HDD and all, so there hasn't been much time for anything bad to happen!

I found out what is causing the explorer.exe's to hang... If you give ANY arguments to explorer.exe in your shortcut/properties, to try to change the default directory from Libraries, it will hang.  For example, simply using "explorer.exe C:" will cause explorer task to hang whent you close it... by hang, i mean the window closes, but the process remains in memory.  I had 15 explorer.exe's tonight....  There are tips on the net about how to get explorer to default to My Computer (which I was using this tip -- i HATE it defaulting to Libraries which i NEVER use)..... so edit your shortcut, and take off any arguments to explorer.exe.  See if this fixes it!

As expected , the tech support is clueless on this I see.

PS -- I just figured out how to default Explorer to My Computer... Its weird, but it works...  Rightclick drag your My Computer icon on the desktop over to a blank space.  Create a shortcut....  Now unpin any Windows Explorer you have from your Taskbar... Now, left-click drag your My Computer shortcut to the taskbar.    Now, if you just click this, you go to Libraries.... BUT -- if instead you right-click it, you will see the My Computer shortcut, and select this, and it goes to My Computer.... and there are never any EXTRA explorer.exe's hanging around!

    I'm having a variant of this one, I have 22 examples of explorer.exe runnind in task manager. 20 of them are located in C:\Windows\winsxs . This is in Windows 7 Home Premium, 64 bit with sp1 recently added. You're the expert- suppose you tell me how all those came to be in there and how to fix the problem.

    Open file location, in any non explorer.exe software causes this glitch each time!!!

     (I am aware of the other problem with this regarding the taskbar buttons and what not but i believe the solution would be basicly the same and im not elaborating on that problem because I dont know much about that one as its not the problem that affected me)

    So I google search, i came across the first few results, mostly forum and it was this page that mentioned the using utorrent and "open file location" command as each time it is an additional explorer.exe in the task manager suddenly using about 10,000kb of memory in each of the additionals as a result. I put 2 and 2 together realizing just a few minutes previously upon downloading a file in firefox browser i used the "open file location" option that is so popular of a command nowadays. why i had in fact done it twice and with 3 explorer.exe running in my windows 7 I killed the processes of low memory which would obviously merit low importance in comparison to the main 26,000kb process. I had a hunch. the largest would be the main so dont kill that one. it is quite simple I tested my theory that using the command opens an additional explorer.exe and this holds true in windows 7 each time you do it when you use the "open file location" command in any 3rd party software such as utorrent or firefox.exe, atleast as i have tested this in task manager itself using the "open file location" command and it appears windows recognizes itself and prevents the extrenuous process from running at all. Basicly if you use the command "open file location" with any 3rd party program or perhaps even any program other than explorer.exe itself it will cause the additional processes to appear and even "hang" around in the background so to speak after closing the explorer window in question. 

    With 5 minutes of research and 30 seconds of thinking from a somewhat computer literate average individual like myself I have found the solution and the most likely cause of the problem that everyone is missing, I have one upped the tech support engineers all of them that Ive ever seen online or met. none had an explanation, yet the answer being quite simple indeed.I hope this helps everyone across all forums those I have seen.  (Dont worry if you kill the main explorer.exe that runs normally windows automatically  reboots the main explorer.exe process upon termination. you will barely notice it actually.)

    I must correct you, as i have had this problem. when you open file location with utorrent or firefox closing utorrent and firefox programs do not terminate the extra explorer.exe process's that linger as a result of  "open file location" they stay long after everything is closed other than those processes themselves.
