Stisvc.exe
(Microsoft)
Still Image Service. This is the equivalent of STIMON above but for Windows 2000/XP.
Recommendation :
On Windows 2000 and XP most scanners and many digital cameras will not work if you stop this service, as the drivers integrate tightly with STISVC, so leave it alone. The foregoing notwithstanding, there are problems with many HP scanner drivers which cause STISVC to run away with 99% of CPU usage if your PC is sluggish immediately after you have attempted a scan with your HP scanner, then try downloading the latest drivers for your scanner through our section. If that does not solve your problem, then de-install your scanner drivers, next go into "Control Panel \ Administrative Tools \ Services" and set the Still Image Service to "Disabled", stop the service, reboot, then re-install the drivers. That may just solve your problems.
