if it is running then my minimax cdma modem will not work, the error is "Another program is using the device"

ehsched.exe is a process belonging to the Microsoft Media Center which adds additional multimedia functions to this operating system. This program is a non-essential process, but should not be terminated unless suspected to be causing problems.

On my eMachines T5048, neither internal or external modems would answer incoming calls (fax or LapLink) with ehsched.exe running. Disabled it in Admin Tools/Services and modem(s) work fine. Could care less about MCE functions. My personal rating - PITA.

Best practices for resolving ehSched issues

A clean and tidy computer is the key requirement for avoiding problems with ehSched. 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.
