By default the operating system creates a kernel memory dump which is not enough to find out the reason for the failure. In this case a complete memory dump is necessary. You can get complete memory dump the following way: 

1. In the bottom left corner of the screen, click Start.
2. Select and right-click My computer.
3. In the menu select Properties. 

4. In the open window click the Advanced system settings link.
5. In the System Properties window on the Advanced tab under Startup and Recovery click the  Settings button.
6. In the Start-up and Recovery window under Write debugging information in the drop-down menu select Complete memory dump. 
7. In the Start-up and Recovery window click OK. 
8. In the System Properties window click OK.
9. Close all windows.

10. In the Write debugging information section in the Dump file field you can choose the folder where the created dump should be saved. By default, the dump file is created by the operating system in its own folder in the MEMORY.DMP file. 25 GB of free space on the disk or more are necessary to successfully save the complete memory dump upon the system crash.

10. Reproduce the problem once again. 
11. Make sure the complete memory dump file has been created successfully.

Send a request to Kaspersky Lab technical support via the My Kaspersky Account service. Attach the received memory dump to your request. In the request give detailed description of the problem and what actions should be performed to reproduce the problem.
