Yes I had reintalled the XAMPP again. And also tried to install in differ folder and drive. Everything running with the admin privilages.

Thanks for your help, tried implement the same. Like I had changed the port numbers which are not existing 8088 and 444. but it is the same. I am getting an error: appache shutdown unexpectedly. This may be due to a blocked port, missing dependencies, improper privileges, or a shutdown by another method.

I cant end that particular process as it is using the system as user name and pid is 4. the description for that username process ius NT Kernal & System.
If we end the process then it would be restart as it is NT Kernel and System.

Yes it is the same. I shall write the complete error kindly check.
