If you define 32bit app startup environment for the users, these users might experience a problem with slow log-off. This problem does not affect Full desktop and it does not happen if a user has not printed something from an application.
In case you have Terminal Services Log installed on your server you can check processes being run for each user session. All 32bit sessions will have a process splwow64.exe running. By further investigation we found out that the session will not end until this process does not end (in few minutes). This process is converting between 32 bit and 64 bit applications. The process remains in memory in order to increase system performance and unloads from memory after the last print job.
Adjusting Process TimeOuts
You can define how long the process stays in memory. Open regedit and find the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\
Create new 32bit DWORD SplWOW64TimeOut and set it to one minute (decimal 1). This will add one minute delay to unloading the process from the memory.
If you want to unload the process immediately and log off instantly after the print job is finished we need to add one more registry value.
In regedit open:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\SysProcs
and add new 32bit DWORD called splwow64.exe and set it to decimal 0.
Now the session with startup environment setup will log off immediately after the print job is finished if that is requested by the user.
