Access Denied when ending a not responding program even as Admin

When a program just doesn't responds, I go into the Details tab of Task manager and tried to end a process, but I get the error that Access is denied even as I'm on administrator. I try to look for other solutions but come back UNSOLVED. I don't want to restart the WHOLE thing thus loosing my data
