Turn Off Dynamic Help

By Turn off dynamic help we can improve speed of visual studio.
Another issue that Visual Studio .NET helped to resolve was Dynamic Help starting during startup.
Dynamic Help is another part of Visual Studio that tends to slow everything down. It is a good idea to make sure
the Dynamic Help window is not open when you start up Visual Studio—this is done by simply making sure the
window is closed when you close Visual Studio.
If you never really use Dynamic Help, you can disable it completely. To do this, you need to delve into the
registry and change the value of the key located here:
HKEY_CURRENT_USER\Software\Microsoft\Visual Studio\<7.1>\Dynamic Help
The name of the key is Never Show DH on F1, and you will need to change the value of this key to YES. Doing
this will disable Dynamic Help.
