软件介绍：

Hotkey control is the award winning and easy to use solution for creating keyboard shortcuts for routine tasks like opening files, changing system volume, controlling display brightness, typing frequently used text, controlling active windows and recording macros. Volume and brightness level are shown smoothly on screen similar to OS X on Macbooks. And, a handy Hotkeypanel ensures that you never need to remember all your hotkeys by letting you execute them quickly from a single easily accessible window. In addition to normal combination hotkeys, you can use single keys such as function or number pad keys.

Additionally, you can remap your keyboard layout at a system level and customize your keyboard's key configuration to improve your productivity.

破解过程：
1、打开软件随便信息进行注册，得到错误信息“Please enter a valid username and serial number”；
2、dnspy加载Hotkeycontrol.exe，搜索错误信息字符串

private void a(object A_0, EventArgs A_1)
{
    //注册码总长度15，除"-"长度为12，比如"111111---111111"
	if (this.d.Text == "" || this.c.Text == "" || this.c.Text.Length != 15 || this.c.Text.Replace("-", "").Length != 12)
	{
		MessageBox.Show("Please enter a valid username and serial number.", "Hotkeycontrol", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
		return;
	}
	global::f.a(string.Concat(new object[]
	{
		"https://inchwest.com/logistics/ln.php?cat=hotkeycontrol&evtname=",
		this.c.Text,
		"&evtval=",
		o.a(),
		"&t=",
		new Random().NextDouble()
	}));
	base.Hide();
	Application.DoEvents();
	this.k.Visible = false;
	this.l.Visible = true;
	base.Width = this.l.Width;
	base.Height = this.l.Height + 20;
	base.Top += 60;
	base.Left += 20;
	base.ControlBox = false;
	base.UseWaitCursor = true;
	base.Show();
	Application.DoEvents();
	new Thread(new ThreadStart(this.c)).Start();
}

3、进入new Thread(new ThreadStart(this.c)).Start();

private void c()
{
        Application.CurrentCulture = new CultureInfo("en-us");
        //此处if必须为false,即o.a(this.d.Text, this.c.Text)需返回true
        if (!o.a(this.d.Text, this.c.Text))
        {
                base.DialogResult = DialogResult.Cancel;
                return;
        }
        this.m.Invoke(new k.a(this.b));
        MessageBox.Show("Hotkeycontrol has been registered successfully.", "Hotkeycontrol", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
        base.DialogResult = DialogResult.OK;
}

4、继续进入if (!o.a(this.d.Text, this.c.Text))；

                catch (Exception)
                {
                        MessageBox.Show("Could not save registration data. Make sure that the directory from which you are executing has write permissions.", "Hotkeycontrol error", MessageBoxButtons.OK, MessageBoxIcon.Hand);

        if (flag)
        {
                MessageBox.Show("This serial number is registered for Hotkeycontrol 7 which is not valid for this major release.\n\nPlease visit [url=http://www.inchwest.com]www.inchwest.com[/url] to purchase a Hotkeycontrol 8 license at a significant discount.", "Hotkeycontrol - Old license", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);

        }
        return false;
}

5、根据代码分析进行修改，定位待修改处的IL代码；
