Keep in mind the most IMPORTANT step in the following is creating a backup of the Registry...
That being said:
To disable sending crash reports of Internet Explorer, you must do the following:
1. Click Start, Run
2. In the Open box type the command regedit and click OK to launch the publisher of the registry
3. Go to the HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ Main
4. For this key, locate the entry DWORD named IEWatsonDisabled. If it does not you can create as follows:
* menu Edition Pull down the Edit menu
* Click New, DWORD Value, type the name of the new DWORD value
(IEWatsonDisabled)
5. Double-click DWORD Value IEWatsonDisabled. and set its value to 0 (in the field Value data)
6. Create a second DWORD value as described in step 4 (steps 4-1 and 4-2), the IEWatsonEnabled name (if it does not already exist). Put the value 0 in the field Value data
7. The changes are taken into account immediately, and error reports IE will no longer be sent to Microsoft engineers.
