Answer 1

Ok gyus, i wrote class that can get installed programs from registry without hotfixes and updates. It is still not exactly like in control panel but almost. I hope this helps anyone else.

public static class InstalledPrograms
{
    const string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";


    public static List GetInstalledPrograms()
    {
        var result = new List();
        result.AddRange(GetInstalledProgramsFromRegistry(RegistryView.Registry32));
        result.AddRange(GetInstalledProgramsFromRegistry(RegistryView.Registry64));
        return result;
    } 

    private static IEnumerable GetInstalledProgramsFromRegistry(RegistryView registryView)
    {
        var result = new List();

        using (RegistryKey key = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, registryView).OpenSubKey(registry_key))
        {
            foreach (string subkey_name in key.GetSubKeyNames())
            {
                using (RegistryKey subkey = key.OpenSubKey(subkey_name))
                {
                    if(IsProgramVisible(subkey))
                    {
                        result.Add((string)subkey.GetValue("DisplayName"));
                    }
                }
            }
        }

        return result;
    }

    private static bool IsProgramVisible(RegistryKey subkey)
    {
        var name = (string)subkey.GetValue("DisplayName");
        var releaseType = (string)subkey.GetValue("ReleaseType");
        //var unistallString = (string)subkey.GetValue("UninstallString");
        var systemComponent = subkey.GetValue("SystemComponent");
        var parentName = (string)subkey.GetValue("ParentDisplayName");

        return
            !string.IsNullOrEmpty(name)
            && string.IsNullOrEmpty(releaseType)
            && string.IsNullOrEmpty(parentName)
            && (systemComponent == null);
    }
}
