uwfmgr does not release registry RRS feed

  • Question

  • Greetings MSDN Community

    I'm writing a c# program to manage the uwfmgr registry exclusions.

    I execute the following command.

    uwfmgr registry get-exclusions.

    Afterwards, when I want to read the registry, I get an exception with the message:

    No more data is available.

    This problem persists until the next reboot.

    I suspect, that uwfmgr does not release the registry key properly.

    I've made a minimal example to demonstrate the error.

    using System;
    using System.Collections.Generic;
    using System.Diagnostics;
    using System.Linq;
    using System.Threading.Tasks;
    using System.Windows.Forms;
    using Microsoft.Win32;
    namespace WindowsFormsApplication2
        static class Program
            /// <summary>
            /// The main entry point for the application.
            /// </summary>
            static void Main()
                    Process proc = new Process();
                    proc.StartInfo.CreateNoWindow = true;
                    proc.StartInfo.UseShellExecute = false;
                    proc.StartInfo.RedirectStandardOutput = true;
                    proc.StartInfo.RedirectStandardError = true;
                    proc.StartInfo.FileName = "C:\\Windows\\Sysnative\\uwfmgr.exe";
                    proc.StartInfo.Arguments = "registry get-exclusions";
                    string output = proc.StandardOutput.ReadToEnd();
                    string[] subkeys = Registry.LocalMachine.GetSubKeyNames();
                catch (Exception ex)
                    MessageBox.Show(ex.Message + "\n" + ex.StackTrace);


    • CLR is ".Net Framework 4.5".
    • Target is "Any CPU".
    • The executing system is "Windows Embedded 8.1 Industry Pro".
    • The architecture is 64bit.

    Now, is there any possible way to force uwfmgr to release the registry?
