Hi NagibMahfuj, Look at the Event Logs for clues about the crash. 1. Click Start, type eventvwr.msc and press [ENTER} 2. Expand "Windows Logs" category, and select "Application" 3. Identity the entry shows in Red exclamation icon, which matches the date/time at which the Windows Explorer crash occurred. 4. Right-click on the entry, click Copy, and click Copy Details as Text 5. The log entry is now copied to the Windows Clipboard. It probably has more details on what exactly caused Explorer to crash. 6. Paste the info (CTRL+V) along with your reply.

Hi, First, since this problem occurs after you installed a third-party codec, I would suggest you to perform a Clean Boot to narrow down whether this problem is caused by third-party software. http://support.microsoft.com/kb/929135 Note: Clean Boot is a step of troubleshooting, we can go back to normal by running MSCONIFG. If this problem disappears in Clean Boot, you may use half and half method to ensure which software caused this problem. If the issue persists, please try to disabled preview feature by following steps: Suggestion 1: ===================================== 1. Open Windows Explorer, click Organize. 2. Click Layer Out and uncheck the Preview pane. 3. If the issue disappear please try to rebuilt icon cache and check media codec, you can run following command in Command Prompt with administrator permission to rebuilt icon cache. taskkill /IM explorer.exe /F cd /d %userprofile%\AppData\Local del IconCache.db /a Suggestion 2: ===================================== If the issues still persists after following suggestions above, I suggest that you may create a dump file for Explorer.exe then we can analyze the file and find the root cause: To use Windows Task Manager to create a user-mode process dump file in Windows 7, follow these steps: 1.
