Generating a small memory dump in Windows

In the case of a system crash, AVG Support may ask you to provide a small memory dump from your PC. A small memory dump is the smallest type of dump file (64 KB) and includes the basic data of the system memory. Follow the steps in this article to generate a small memory dump in Microsoft Windows on systems which are not completely frozen.

For information about other types of memory dumps that AVG Support may request, refer to the following articles:


  1. Log in to Windows as a user with administrative permissions.
  2. Download the avkb58.zip file. Then, at the bottom of your browser window, click the arrow next to the file name and select Open.
  3. Download the avkb58.zip file, select Open with in the window that appears, then click OK.
  4. Download the avkb58.zip file and click Open.
  5. Download the avkb58.zip file and click Open in the window that appears.
  6. Double-click the avkb58 folder, then double-click the FullCrashOnCtrlScroll.reg file and select Run in the Security Warning dialog.
  7. When prompted, click Yes to allow the application to make changes to your PC.
  8. Click Yes, then OK to apply the necessary changes to your Windows registry.
  9. Restart your PC, log in to Windows as a user with administrative permissions, and wait until the system or application freezes again.
  10. Manually force a Windows crash by holding down the Ctrl key on the right side of your keyboard and pressing the Scroll Lock key twice (right Ctrl + 2x Scroll Lock).
  11. A blue screen appears (the 'Blue Screen of Death'). The system generates a memory dump (progress is indicated in percentage) and restarts automatically.
If your PC does not restart automatically, restart your PC manually by pressing the Reset or Power button.
  1. Log in to Windows as a user with administrative permissions and locate the MEMORY.DMP file in C:\Windows (by default).

Once you have created the dump file, send it to AVG Support.
