This is a web server for windows, it's not dangerous at all. But some time this application create a problem for Web Designer & Web Developer's. Because this application use Port 80, and also Wamp (Apache) / Vertrigo (Apache) use same port 80. So Vertrigo And Wamp server do not run. If any user relise this type of problem then please follow the some step "OR" open the given like and solve this porblem. Reconfigure Apache to run on a different port::::- You might want to pick this path if you don’t want to close the application blocking port 80. A typical reason might be that you want to run say, Apache and IIS on the same machine at the same time. 1. To configure Apache to run on a different port,. Go to : (C:\Program Files\VertrigoServ\Apache\conf\httpd.conf) Then Right Click On httpd.conf and open in note pad then Search for the following lines: a. Listen 80 b. ServerName localhost:80 Change both these lines, so as to have a different number instead of 80. I have chosen 8000 instead of 80. Make sure that this is a free port, not used by any applications. a. Listen 8080 b. ServerName localhost:8080

its reduce my server performance.
windows component, provides server functions like mailing, ftp etc, but no need for it on average home pc. if running anyway (see task-manager) may indicate malware infection (botnet)! See also IIS Admin service (deactivate if you don't host a server).

Best practices for resolving inetinfo issues

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