Windows Explorer Oftenly Crash in Windows7
I have a problem that Windows Explorer had been crash many times when I explore harddisk directory. I didn’t install new software. I cannot find the root cause of this anomaly issue. Finally, when my Windows got crashed again, I attached explorer.exe to a debugger. Look in Call stack and module loaded.

ntdll.dll!0000000077033281()Now, I found temporary workaround. First, my explorer.exe get integrity check with the other. the explorer.exe MD5 has the same string mean that my explorer.exe is original and doesn’t infected by any virus. Some comments tell to fork new explorer process. I do it and it return the better result.
At this time, my Windows Explorer has no more crash. but if it crash, it will terminate only process which handle that windows and not impact to all opened windows.
For anyone who has the same problem…. you can try
Folder Option > Launch folder windows in separate process.
Hope these will be your workaround.
My Systems: Windows7 x64.
