In cases other than the above, perform the following procedure to enlarge the desktop heap by correcting the registry. There is no particular method for estimating an appropriate value, so increase the size gradually.
Open the registry editor.
Select Run from the Start menu. Enter "regedt32", and then click OK.
Move to the SubSystems key.
From the HKEY_LOCAL_MACHINE subtree, move to the following key.
\System\CurrentControlSet\Control\Session Manager\SubSystems |
Select the Windows value.
Select Modify from the Edit menu.
Increase the desktop heap by changing the value of the SharedSection parameter.
Increase the value of the third item "zzzz" (in increments of 256 KB or 512 KB).
SharedSection=xxxx,yyyy,zzzz |
Note: There is no need to change the first and second values ("xxxx" and "yyyy").
Example: Before change
SharedSection=1024,3072,512 |
Example: After change
SharedSection=1024,3072,1024 |
Restart the system.
