Warning This article offers information about how to work around issues that are caused by changes in this release of Windows Help. However, Microsoft makes no specific recommendations about which registry keys and which values are right for your unique environment. If you are in a managed environment, your IT department is the best judge of how to weigh the advantages of these workarounds against the risks of using them. The safer course is to use no registry workarounds at all.
