Thanks for that and no need to apologise all is now cool.
Open the Task Manager then click on the Processes tab and look for and kill the xampp-control.exe process.
Then go to the xampp installation folder and right click on the xampp-control.exe file and select to run as an administrator and see if the control panel opens.
You should then be able to remove the ticks in the Svc boxes to remove the Windows services.
Best if you are logged into Windows as an Administrator but even then often right clicking on bat and exe files in XAMPP and selecting to run as an admin seems to give more privileges.
