Microsoft Help Center Service – Windows XP. In our experience you will only see this task running if you have Automatic Updates turned ON or if you are in the process of running a Windows Update, or you access the Windows XP Help, as this task’s main job is to install Microsoft updates to the Windows XP Help and Support Center, and most specifically, new Headlines.
Recommendation :
In most cases this task terminates once the Windows Update terminates and/or you exit the Windows XP Help. It has been known, however, not to terminate itself and instead to run away with CPU usage, up to 90%, with the obvious impact on the PC’s performance. If this happens regularly create a DWORD entry called Headlines and give it the value of 0, for the following Registry Key HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ PCHealth \ HelpSvc \ (only advanced users should attempt this). This disables the Headlines feature which simply means that your Help and Support Center headlines are never updated.
