I have some users connected to windows server 2003 64 bit system via terminal. My problem is that, when a user tries to print any document and tries to close session than after that it gets hanged for some minute. I have checked out for this issue and have found it to be happening because of Splwow64.exe process , it is used for conversion between 32 bit and 64 bit applications and remains in memory for increasing performance. It unloads from memory automatically after completing its task. The time taken for it before unloading memory can be set by editing registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\SplWOW64TimeOut(DWORD) but minimum value is 1, if i set it to 0 than application gets hanged completely. I want to know if it is possible to get this process unloaded from memory just after its task gets completed???
