Solution 1

GetProcessesByName takes the process name, not a regex that the process name matches.
You probably want something like this instead...

C#

foreach (Process P in Process.GetProcesses())
{
    if (P.ProcessName.StartsWith("U", StringComparison.CurrentCultureIgnoreCase))
        P.Kill();
}

Solution 3

C#

Process[] Processlist = Process.GetProcesses();
            foreach (var process in Processlist)
            {
                if (process.ProcessName.StartsWith("u"))
                {
                    process.Kill();
                }
            }

See my comments to Solution 2 - this will NOT work if you have any processes beginning with capital-U (compare 'UNS' with 'unsecapp' for example)

Solution 2

C#

Process[] Processlist= Process.GetProcesses().ToArray<process>();
foreach (var process in Processlist)
{
  if (process.ProcessName.StartWith("U")){
    process.Kill();
 }
            }</process>

Process.GetProcesses() returns a Process[] so there is no need for the .ToArray(). In any event your solution produces 5 compile errors:
- "</process>" ... take care when pasting code in
- ProcessName.StartWith? should be ProcessName.StartsWith
- ToArray<process>() - what is a "process"? I suspect you meant Process - which is completely redundant.
Fix all those issues and what you have left is Solution 1, with the exception that my solution will find (for example) both UNS and unsecapp but your's will only find UNS
