Spool32.exe
(Microsoft)
Spooler Sub System Process for Windows 95/98/ME. SPOOL32 is a hidden task, a task that does not show up when you press Ctrl+Alt+Del, but which will show up in Starter or any Task Process viewer, such as Task Info 2002 or WinTasks. SPOOL32 manages the spooling of print jobs. Spooling allows the computer's processor to quickly process a print job by temporarily storing it on the hard disk before sending it to the printer. This allows the processor to return control to the program from which you are printing at a much faster rate than if the program were to process the entire print job and then send it directly to the printer. Note that SPOOL32 will only spool print jobs if you configured your printer to spool print jobs.
Recommendation :
Essential this task auto-loads at boot-up leave it alone. If you experience SPOOL32 errors, your problem is not with SPOOL32 but with something else on your PC, quite often the printer drivers.
