The (NTSTATUS) 0xc000041d - An unhandled exception was encountered during a user callback crashes are mostly caused by damaged Windows files. Please start the command prompt (cmd.exe) with admin rights [1] and run sfc [2]: sfc.exe /scannow Is it able to find and repair broken files (create the txt file shown under [2] and look if all files are restored)? Now look if the Explorer still crashes. If not, this fixed it. best regards André [1] http://windows.microsoft.com/en-US/windows7/How-do-I-run-an-application-once-with-a-full-administrator-access-token [2] http://support.microsoft.com/kb/929833 "A programmer is just a tool which converts caffeine into code" Want to install RSAT on Windows 7 Sp1?

This is a rather interesting one. Basically what happens is every now and again (no easy way to reproduce) explorer will just crash when I try and copy/cut and paste a file (CNTRL-C/V or X/V). I have configured Windows 7 to drop a dump file any time an application crashes so I have a dump file, but the results of the dump file are rather cryptic and not much help. Basically it tells me that there was an error in the shell32.dll. I have disable most of my shell extensions. The only one that is still active is my anti-virus. All of my other computers do not have this problem.
