More Information:

The initial SharedSection value 1024 states that the heap size is common to all computers. This contains the global handle table (Window handles are unique machine-wide) and shared system settings (such as SystemMetrics). It is probably, that you would never want to change this value.

The second value of the SharedSection registry entry is the size of the desktop heap for each and every computer that is associated with an interactive Window station. The heap is needed for every desktop that is created in the interactive window station (WinSta0). The value is in kilobytes (KB).

The third SharedSection value 512 and controls the size of the desktop heap for each computer that is integrated with a non-interactive window station. If this value is not present, the size of the desktop heap for non-interactive window stations will be the same as the size particularized for interactive window stations (the second SharedSection value).

We increase the second value of the SharedSection registry entry to 20480 and increase the third value of the SharedSection registry entry to 1024 in the automatic fix.

A value that is higher than 20480 KB for the second SharedSection Value is NOT recommended.
