Windows 7: Windows Explorer crashing randomly

Windows Explorer crashing randomly

Hi,

Have encountered this problem recently, not sure if it is due to me cloning my HDD onto a new SSD or due to a recent windows update/software installation.

Windows explorer will crash randomly, sometimes while playing a game, browsing the net, or even when idle. It will then attempt to automatically restart Windows explorer and everything reverts back to normal. This happens about 3-4 times randomly in about 8 hours. While it is restarting explorer, mouse movement is very sluggish.

So far, all important windows updates are successful. For shell extensions i have eraser, teracopy, winrar, malwarebytes anti malware, norton ghost and magicISO. These extensions were installed long before the problem surfaced. I have also done a sfc /scannow but did not find any errors.

I did remove my optical drive and replace it with a 2nd HDD caddy with a HDD inside if it matters.



Help is much appreciated

Could you fill in your system specs, please?

You said the shell extensions you added were before this issue started, but for testing sake lets disable the none Microsoft ones. Download this program ShellExView - Shell Extension Manager For Windows which lets you view and enable/disable shell extensions.

Does it also happen in safe mode?

Thanks, will enable them 1 by 1 to try isolate the cause. Will post back on the issue.

Did not try using for extended periods of time in safe mode

Could also try giving this a try as well if you have the entry specified. If you don't have the entry in your registry to delete, then don't worry about doing this:

1. Click Start
2. Type regedit and hit enter
3. Go into the following - HKEY_LOCAL_MACHINE - SOFTWARE - Microsoft - SQMClient
4. Then you should see an entry called "MachineThrottling", backup your registry first (File>Export) and then delete that entry.
5. Close regedit
6. Open Computer and right click on C:/
7. Click the Tools tab
8. Click check now to check for errors (make sure the top box is selected - fix file system errors) and OK
9. Restart your computer

Hi,

Thanks for pointing me in the right direction, the problem ceased after i disabled all third party shell extensions. Will now enable them slowly to isolate the cause of the problem

After re enabling the extensions batch by batch, i was unable to reproduce the problems. Probably an automatic update for a third party extension fixed the issue.

Thanks anyway.

Hello everyone... I had this problem and solved it by examining the tasks in the Task Scheduler.
In my case the offending task was the "Scheduled Update for Ask Toolbar".
They symptom was frequent failures of the Task Scheduler. and the following entry in the event viewer:taskeng.exe
6.1.7601.17514
4ce79d2c
msvcrt.dll
7.0.7601.17744
4eeb033f
c0000005
00000000000027de
98c
01ce2c7b0a8c0dfd
C:\Windows\system32\taskeng.exe
C:\Windows\system32\msvcrt.dll
54b0d3b4-986e-11e2-ad0f-005056c00008

When I reviewed the history of the task in the task scheduler, I could see the multiple starts and failures.

Hope this helps.... will update this thread if I find that my 'fix' was not actually a fix.
