I had recently updated my build 9936 to build 10041. But one of the problem that I got in this build was that I had been working in my computer for few days but today when I opened my computer, I got an error message as: Title as: explorer.exe - Application Error Message as: The instruction at 0x6BC6F580 referenced memory at 0x0A48B030. The required data was not placed into memory because of an I/O error status at 0xc000009c. Click on OK to terminate the program Click on CANCEL to debug the program When I click OK, the explorer restarts and again the message is shown. Cancel does a debug to the Visual Studio. I have included a picture in my post.
