What is agrsmsvc.exe?

The genuine agrsmsvc.exe file is a software component of Agere Soft Modem by Agere Systems.
Agrsmsvc.exe is an executable file that belongs to the Agere Soft Modem, a proprietory modem that uses two-chips and a single-lane PCI-Express interface. This is not a critical Windows component and should be removed if known to cause problems. Terminating this process might disconnect an active Internet connection. The Agere AMR Softmodem takes up more resources from the computer, especially the CPU, to perform part of a hardware modem's job. Soft modems are relatively cheaper to manufacture than their hardware counterparts but are more resource intensive. This is not an issue, however, for faster computers. Agere Systems Inc. was an American company that designed and manufactured integrated circuit components. The company was formed in 2002 after being spun out from Lucent Technologies. In 2007, it was merged into the LSI Corporation. Agere Systems was based in Allentown, Pennsylvania, USA.

Best practices for resolving agrsmsvc issues

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