I accidentally removed my Apache windows service trying to install another Apache web server. Does anyone know how I can create another Apache windows service from cmd? I tried
On Apache 2.2, the command is: httpd.exe -k install
Click Win + R and type cmd
Below Image shows how to install Apache2.2 in windows

Default installation location of Apache2.2 is C:\Program Files\Apache Software Foundation but in my pc I installed directly on C:/ drive.
If you want to install Apache2.2 in Program Files folder then in type in command prompt as follows
C:\>cd Program Files ( Click Enter )
C:\>Program Files>cd Apache Software Foundation ( Click Enter )
C:\Program Files\Apache Software Foundation>cd Apache2.2 ( Click Enter )
C:\Program Files\Apache Software Foundation\Apache2.2>cd bin ( Click Enter )
in bin folder you will find httpd.exe file
C:\Program Files\Apache Software Foundation\Apache2.2\bin>httpd.exe -k install( Click Enter)
The successuful message is displayed in command prompt like above shown in the image.
In Windows 7 or 8 right click the XAMPP Control Panel start (menu) shortcut and Run As Administrator. Then just click the service check boxes for Apache and/or MySQL.
For older versions of Apache:
Apache.exe -k install
net start apache2
Did not work for me using httpd.exe -k install, I had to register apache as a service using sc.exe using:
sc.exe create apache2.4 start= auto obj= "<account>" password= "<password>" DisplayName= "Apache 2.4" depend= "Tcpip/Afd" binpath= "\"c:\wamp\bin\apache\apache2.4.33\bin\httpd.exe\" -k runservice"
On Apache 2.4 the executable have changed name to httpd.exe, the command would be:
httpd.exe -k install -n "Apache2.4"
With a name switch in order to give the service a distinct name.
