ClassicThemeTray - quickly toggle Classic Theme from tray

A command line mode would be useful as well because SCT became too thick for that usage.

This is very useful, thanks!

This program is already very useful, but if you plan to expand it, I have some ideas.

for instance,

* Have an option to delete the theme section forever, as ClassicThemeA.exe does (this may free some memory).
* Have an option to enable and disable Classic Theme for certain session number.
* Have an option to include or not include the System user (UAC prompt on Win8.1, maybe something else as well).

Also,

* On Win8.1 the Fixstrips and removing blur from the taskbar would be very useful (already implemented in SCT)
* Setting UPM bit for 3D menues (also already implemented in SCT).

* Also, what about a version for ARM architecture?

I think this functionality which does not deal with third-party software could be very useful and lightweight.

I do not think these functions should be added to the GUI (lets keep it simple) but only to the command line as separate independent options (e.g, not triggered automatically on /enable).

I tested it on Win 8.1, it works.

Have been using this for a day and it's seriously awesome! Allows me to quickly turn off classic before certain programs load and then enable it again. Sooooo much better than opening sct... waiting 10 seconds... clicking enable... and then having to close it. Nice job!

If you wan't to do almost ANYTHING Classic Theme related, you need to disable defender or any other antivirus. They're just going to give you false-positives. (The issue is that most of these utilities access undocumented API calls and/or API calls that only trusted Windows programs would normally make)

I tried this on LTSC 2016 and it didn't do anything. Am I missing something here?
EDIT: Well I'm a fracking idiot. I forgot explorer would need restarting.

So, I decided to see if I could do anything useful with your program. I was unsuccessful, but I did find something potentially interesting: I've had partial success getting existing Windows to notice the theme change by trying to send the messages an app would normally receive when the Classic Theme is enabled. Thus far, I've not gotten this approach to work 100% correctly in both directions for even a single program, but I have managed to get an existing instance of Windows 7's Task Manager to almost fully switch from Visual Styles to the Classic Theme (but not go back), send File Explorer into an identity crisis, cause Pale Moon to insist on making its titlebars largely invisible, and do some very...strange things to Notepad++, which I can't even begin to understand. While I don't think I'll be able to perfect this approach, I will provide what I have so far, in case you or anyone else are interested in pursuing this further:


       [DllImport("uxtheme.dll", SetLastError = true, ExactSpelling = true, CharSet = CharSet.Unicode)]
       public static extern int SetWindowTheme(IntPtr hWnd, string pszSubAppName, string pszSubIdList);
       
       [DllImport("user32.dll", CharSet = CharSet.Auto)]
       public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, IntPtr lParam);
       
       public static void SendThemeMessages(IntPtr target)
       {
           SendMessage(target, 0x0031, 0, IntPtr.Zero); //WM_DWMCOMPOSITIONCHANGED
           SetWindowTheme(target, " ", " ");

           SendMessage(target, 0x0015, 0, IntPtr.Zero); //WM_SYSCOLORCHANGE
           SendMessage(target, 0x031A, 0, IntPtr.Zero); //WM_THEMECHANGED
           SendMessage(target, 0x000f, 0, IntPtr.Zero); //WM_PAINT
           
           SendMessage(target, 0x0085, 0, IntPtr.Zero); //WM_NCPAINT

           foreach (IntPtr ptr in GetAllChildHandles(target))
               SendThemeMessages(ptr);
       }

Just call this for all currently-open top-level Windows, and it will try to do the rest. And fail miserably, in most cases. Also, this is only tested on Windows 8.1, I have no clue what it'll do on Windows 10 (if anything).

Theres malware..
