What You Need to Know Before Installing This
Get 0n Top is a system utility that forces its window to stay above all other applications on your desktop. It sounds simple enough, and the basic version is free on GitHub. The concept relies on setting a Windows API flag that marks the window as always-on-top. Most people download it, run the executable, and move on with their day. It works for quick, single-use cases where you just need a window to stay visible. I ran into a specific issue a while back where Get 0n Top would lose its priority whenever I switched between monitors on my dual-monitor setup. The window would briefly drop below everything else during the transition, then come back. This happens because the tool hooks into the primary monitor's window stack by default. The fix was launching the executable with the --secondary-monitor flag. It was in the README but easy to miss if you aren't reading every line carefully. I also noticed that certain fullscreen applications like games or video editors would temporarily override the always-on-top behavior. That's not a bug in Get 0n Top. It's how Windows handles exclusive fullscreen mode. The OS gives that application full control of the display hierarchy.
Downloading and Setting Up Get 0n Top
The official release lives on the project's GitHub page. Grab the latest executable from the releases section rather than compiling from source unless you need to modify the behavior. The prebuilt version is stable enough for everyday use. After downloading, run it as a standard user. There's no installer, no registry entries, and no services created. It runs entirely in user space. Here's what most guides don't mention clearly enough. The tool has a tray icon but it's extremely subtle. If your system tray icons are collapsed behind the overflow arrow, you won't see it. Right-clicking the tray icon gives you options to toggle the state, adjust opacity, and choose which windows to apply the flag to. The opacity adjustment is useful if you're running a transparent overlay and want it to sit visibly above everything without being completely opaque.
How It Actually Works Under the Hood
Get 0n Top uses the SetWindowPos Windows API call with the HWND_TOPMOST flag. That flag tells the Windows compositor to keep the target window above all non-topmost windows. The tool then applies this to whatever window you select or to the active window at launch time. There's a second mode that locks the window permanently until you explicitly release it through the tray menu. The counter-intuitive part is that this doesn't actually work the way you might expect when multiple topmost windows are involved. If you have two applications both trying to stay on top, Windows doesn't merge them into a single layer. It creates a stacking order between the topmost windows based on which one was activated most recently. So if Get 0n Top is applied to Window A and you click on Window B, Window B might end up above Window A even if Get 0n Top is still active on it. I learned this the hard way when trying to keep a reference document visible above a spreadsheet and having the reference vanish every time I clicked back into Excel. Another thing people miss is that Get 0n Top does not persist across reboots. If you want it running automatically, you need to add the executable to your startup folder or use Task Scheduler. There's no built-in option for that. The executable is small enough that leaving it in the background has negligible resource impact, usually under 5MB of RAM and virtually no CPU usage.

When This Tool Actually Falls Apart
The biggest limitation is that Get 0n Top only works on regular desktop windows. It cannot make overlays stick on UWP apps, Microsoft Store applications, or games running in borderless windowed mode. Those applications often create their own window layers that bypass the standard Z-order entirely. If you're trying to keep something visible above a modern game, this tool will simply not work and you'll waste time troubleshooting something that was never going to function in that environment. There's also the issue of display scaling. On systems running at 150% or 200% DPI scaling, the window positioning can drift slightly over time. The tool doesn't account for dynamic DPI changes after it launches. If you change your scaling settings or plug in an external monitor with different scaling, you may need to restart the application. It's a minor annoyance but worth noting if you move between machines with different display configurations. If you need something more robust that handles these edge cases, Window Topmost from SoftOrbits or the auto-it based solutions in the community are worth considering. They cost money or require more setup but they handle multi-monitor edge cases better and work with a wider range of application types. Get 0n Top does the basics well. It's just not designed for anything beyond basic desktop window management.
I still reach for this tool whenever I need a quick solution for a single window. It's fast, free, and does exactly what it promises. Just don't expect it to solve problems that are outside its scope.
