Hi Richard,
HHCTRL is Microsoft HTML Help Control center.
Are you facing any issues with Windows performance?
To understand the issue better, I would suggest you to post the event viewer detailed information. However, you may check if you face the same issue in
**safe mode**
wherein the computer starts with basic drivers and no third party programs.
If the issue doesn’t occur in Safe mode, you may try to restart the computer in
**clean boot** mode to check if any third party
application is causing the issue, as clean boot helps in eliminating software conflicts. The steps given in the article are similar to Windows 8.1 operating system.
Note: After troubleshooting, see the section “How to reset the computer to start as usual after troubleshooting with clean boot” to return the computer to a Normal startup mode.
I would also suggest you to provide a screenshot of the error details to assist you better:
