For Vimicro SC0301PL webcam ( driver ) , I need that driver since my webcam can't work on Windows 7 , and i can't find it
It comes after installation of Vimicro web cam driver.
Have used it for six years, needing to update driver only once in that time - worked similar to what most commenters have stated, works with several camera makes or models, runs high cpu and slows comp, easily fixable if you stop it from running at startup - msconfig. If you dont have cd for a vimicro cam instead on just downloading the latest driver, it pays to search out the correct chipname, thats about all that Im aware of.
Got installed with a cheap web cam. Did no harm to my Win XP Pro. Totalvirus say clean
chines cam driver, when you system have idle status - it activated and use 100% system resource, only reset...
it'll system slowly and a little fix at sidebar,if we install sidebar vista on windows XP
It's webcam driver install through window process. A little siege of memory, didn't cause any problem to my computer.

Best practices for resolving vm_sti issues

A clean and tidy computer is the key requirement for avoiding problems with vm_sti. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the vm_sti.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
