Access is denied : AH00369: Failed to open the Windows service manager

When I try to run httpd.exe -k install for Apache on Windows 10, I get an error – “(OS 5)Access is denied. : AH000369: Failed to open the Windows service manager, perhaps you forgot to log in as Administrator?” But I am logged in as the admin since I have only one user account on my Windows 10 computer. What am I doing wrong?

This is not a big issue at all. All you need to do launch Command Prompt as the administrator. Here is what you would be getting.

Follow the instructions below.

1. Click the Windows icon (bottom-left), search for ‘command prompt’ and get it listed.
   
2. Right-click and select “Run as administrator”. If a User Account Control displays a pop-up, simply click on the “Yes” button.
   
3. Now issue the command httpd.exe -k install by moving to the “bin” folder in the Apache install folder (it is c:/Apache24/bin by default).
