JSI Tip 0820. If SP4 breaks your app, it may be the Heap Manager Change.

If you get access violations or lockups in previously working applications, it may be the Heap Manager Change in Service Pack 4.

To verify it is a poorly written application:

Navigate to

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

From the Edit menu, Add Key and enter the application.exe of the executable that experiences the problem, without a path. See the Game.exe sub-key for an example. Class may be left blank. Select the application.exe key and Add Value name DisableHeapLookaside as a type REG_SZ and set it to 1.

If the application.exe is a service, restart the computer.

Now run your application. If you get more or less errors, contact the vendor or search for your application in the Knowledge Base.
