OnTop

OnTop is a small software application whose purpose is to help you toggle the ‘Always on top’ property of any window with the aid of a keystroke. Plus, you are offered the freedom to set the transparency of all windows that are not displayed on top of other panels.

Requires no installation

It’s easy to work with portable utilities because you do not have to go through an installation process in order to gain access to their GUI. OnTop’s features can be accessed by running the executable file.
What’s more, you can keep the tool stored on pen drives or other portable devices so you may carry it with you all the time. You may open it directly from the storage device. It’s easy to get rid of it in case you no longer need it because it does not leave entries in your Windows registry and generate additional files. A simple deletion task does the job.

Look for OnTop in the system tray

The application can be found sitting quietly in the system tray without disturbing your activity. It does not offer support for a help manual, but you can quickly get an idea about how to make the most out of its functions because they look easy to work with. The tool reveals a few hints about its main options via a popup message.
OnTop offers you the possibility to keep the selected panel on top of other windows with the aid of a preset hotkey (‘Win+Alt+T’). Plus, you can make use of another keystroke, ‘Win+Alt+Y,’ in order to set the transparency of all inactive windows. The preset hotkeys cannot be reassigned.
On the downside, the utility has not been updated for a long time so you may come across compatibility issues on newer operating systems, like Windows 10 and 8.

Final words

All in all, OnTop comes packed with a simple set of options for helping you keep certain windows on top of other programs and modify their transparency.
