It's a file from MSI, better known for their motherboards and graphics cards. This file was installed when I installed MSI's Afterburner. Which is a graphis card monitor, overclocker, utility tool, giving a person pretty much almost absolute control over their graphics cards performance.

Beim Start unter Win10Home öffnet sich bei mir ab und zu ein Command"-Fenster ohne das ich die Startrampe finde auf der Suche danach bin ich über die Datei gestolpert die kein separates Icon hat. Ihre Seite ist Top!!!

Best practices for resolving muachost issues

A clean and tidy computer is the key requirement for avoiding problems with muachost. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
