Hi,
check these things first:
what os are you using?
Do you have big files in C:\ or in the folder you are using ( like desktop folder ) that are needing previewing (big images and videos)  ?? .
explorer.exe updates sometimes preview images for some reasons. ( the same thing happens also on linux with nemo or nautilus ( both explorer.exe equivalents)!).
Think that is the case on your system.


Also do you have enough space left on your main hard disk ?

Is a disk or floppy or cd/dvd/bluray disk attached /inserted that is corrrupt or damaged . ?
It  Don' t need to be physical or cause data loss , sometimes its only a simple software based sector fault for unused space. ( happens often for Eink- readers or cheap sd/MMC/SDHC cards!)) ??. A case like this won`t cause any data loss ( except for deleted files ), but can slow down the system a lot ( even prevent from booting).
So try to run chkdsk or scandisk on your smaller disks . ( they schould be included in win7 (even if they aren hte ones from w95/98bluedxca93 anymore)

On my 3ghz dual core win7 64 bit explorer.exe crashes every 2 minutes. Have only 1 gb left and my file system is nearly damaged.But i do know why ( cause of writing files with other  OS to disk ) and i don`t mind it .

b.t.w im still a visitor on this site and it took me 3 min to open this reply window ( damn interente connection)

Thanks, guys.  None of this has worked.  Anybody else have any suggestions?  Thanks.

hi  

check  to be logged in only once. ( on windows you can normally use the switch users section b.t.w).

 Its hard to find the  problem with explore.exe since it controls a huge part of the microsoft systems. 

Disabling some system startup services could help Gaspershooters is right there  ( on my pc there were some unecessary macafee + toshiba + nero services. ). Also some programs do start there support "service" with the windows service list and not autostart ( cause its harder to remove them this way). Happens  often with toolbars or wrong antivirus software. Some applications also use it for their registrated/activated control programm services. 

But be also aware that disabling the false system services might even break your system or a part of it. Normally you can decide if the service is essencial for the system  by their description but not always, if you are unsure google which ones are necessary and which ones aren`t.  Look also how much cpu they use (perhaps there is already the connection with the explorer instances bug).

I finally found the culprit. After a repair reinstall of Windows 7 didn't fix the problem, I went all out and did a full format and reinstall of Windows 7.

Installed all windows updates, all is well.....

Installed several of my Must Have Stardock Products, and the problem returned.

So, I uninstalled all Stardock products, problem is gone again.

After several install/uninstalls of various Stardock products, I finally narrowed it down to DeskScapes 8.  Without DS8, I have no multiple explorer.exes in task manager bogging down a system with 12 GB ram, a 6 core cpu, and an SSD.

I am currently running DeskScapes 3 with no problems.

Also running Fences 2, WindowBlinds, CursorFX, WindowFX.

So, if you still have the problem, try uninstalling DeskScapes8. Remember to deactivate it first, via about.

Deskscapes 8 version 8.10 works without the multiple explorer.exe as well.

If you're getting multiple instances of Chrome a virus is likely the suspect. Chrome isn't as secure as some believe it to be.

Have you tried any online scans?

Try this registry fix:

Change HKEY_CURRENT_USER/Software/Microsoft/Windows/Explorer/Advanced/SeparateProcess to 0 and then reboot.

None of the above works.  I currently have six explorer.exes.

I got rid of Chrome for that reason, even though I had zero addons, plus really crazy adds and something else very weird. On this site only every time I clicked on something and it didn't matter what it was, I noticed a quick download. I looked in my download folder and found something called file. I immediately deleted itthen 86'd Chrome. I now use Whitehat Aviator exclusively.

Zero addons on Whitehat. No adds and I have no problem viewing videos.

Ugh!  The problem has returned for me after 2 weeks of running cleanly.   [e digicons]:'([/e]

If the OP ever finds a solution that works, please post it here.  Going to check my registry but I doubt it's reverted to the old setting.

You shouldn't have to do that, but it worked for me. It's all you can do until they fix it. That or just live with it.
