Please download this reg file from my SkyDrive: http://cid-128fc518635be2dc.skydrive.live.com/self.aspx/.Public/MS%20Foren/Registry/WER%5E_Explorer_full.reg and make a double click on the .reg file to import it. When the Explorer crashes, Windows Error Reporting Service (http://msdn.microsoft.com/en-us/library/bb787181%28VS.85%29.aspx) creates a dmp file under C:\Localdumps. Please upload the dump file (compressed as 7z to reduce the size) to your public Skydrive/dropbox folder and post the link here. After you generated the dump, run this reg file to stop dump creation: http://cid-128fc518635be2dc.skydrive.live.com/self.aspx/.Public/MS%20Foren/Registry/WER%5E_Explorer_full_uninstall.reg
