used for call waitint indication with v.92 modems
essspk.exe is installed alongside ESS V92 modems. Allows a pop-up on the computer screen if call-waiting is detected while the user is using the Internet. This is a non-essential process. Disabling or enabling this is down to user preference
This program is a feature of some dial-up modems, for not missing calls while you're online.
it is from the modem (creative)
regarding "no visible window", there is a tray icon when the modem connects. Click once on it to open window which allows you to disable modem on hold facility. Removal will disable any indication of call waiting while modem is in use.

essspk.exe hat die selbe dateigröße wie domino.exe und vmsnap3.exe, essspk scheint ja zum modem zu gehören, die anderen beiden dateien zu einer webcam. ich frage mich, warum es mehrere dateien gibt die identisch aussehen (heine herstellerangaben etc), gleich groß sind, mit windows gestartet werden aber scheinbar einen ganz unterschiedlichen zweck erfüllen trotz identischer dateigröße, müsste nicht wenn die dateien etwas unterschiedliches tun auch der code unterschiedlich groß sein?

Best practices for resolving essspk issues

A clean and tidy computer is the key requirement for avoiding problems with essspk. 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 essspk.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. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
