    • No,
      It is very hard to develop it so it can’t be free.
      Actually there is even a chance that the price will be higher in the future. 
      5.99$ is low price 🙂

      But you always can use the limited version if you want.

    • Follow these steps:
      1. Right-click on WIndowTop tray icon
      2. Go to “WindowTop Pro” -> Click on the first item
      3. A new window should open. Click on the button “Activate / Buy now”
      4. A small window should open. In this window, you can paste the activation key.
      Paste the activation key and then click on “Activate now”

      At this point, if the key is valid, the program should be activated.


  1. do you plan a tray minimizer function ? if yes, I’ll take without hesitation, I’d like the 2 functions always on top or tray minimizer in the same software

  2. Hello, as you said, the activation license key can be used for up to 3 computers. I’d like to know whether the license can be transferred between devices? I usually work in a VM, and I don’t want to buy a license every time I destroy the VM.

    • Hello, if you use the portable version (not the version you install) you should be safe.
      But please note that in the portable version some of the pro functionality is disabled and it is: dark mode pro and smart transparency
      Other pro functionalities such as the How to watch videos while working (PIP Mode) will be available also in the portable version.

      We plan to add option to remove computers from the activation key so you will able to use it as solution for the installed version.
      For now, if you don’t need the pro functionality that disabled in the portable version, the good option is to use the portable version.

    • Hello,

      1. if you lose your license email, contact us on and if we have a record of your purchase, we will send you the activation key.
      But it is highly recommended to backup the license key for your computer.

      2. We should provide option to remove computer from the license key. For now, there is no such option yet.
      If you want to transfer the license key to another computer, contact us about your request and we will do it for you.

  3. WindowTop is so useful, I use it for SO many things while I’m working.
    I LOVE IT. It’s probably one of my two favorite computer things (the other one is a foot switch/pedal, which means I can make things happen on my computer just by pressing one of the three pedals at my feet).

  4. Does the PRO Version make it possible to define any window of the same program to have sticky settings? Specifically I would like any explorer-window to have alphatransparency…

  5. Moisés Fernández Ballantyne

    I really loved this software. I came across with it because I was trying to solve some issues while streaming on Twitch. I wanted to have my real chat on top of the game, but also, being able to modify transparency and size.

    One thing I’m not sure if its possible: Can you capture an specific part of one window? For example: I would like to capture only the “chat” box of an entire website I’m navigating. It would be interesting if you can “Crop” your selection and then shrink it as a pop up window. Is this possible or it’s not a function implemented on the PRO version?

    Once again, thanks a lot for this amazing software 🙂

  6. Hi, this product is very helpful and is exactly what I was looking for. There is one problem though, when I click the green arrow, no menu comes down. I’m not sure if this is a general problem or a problem on my end. Hoping you could help out, thanks!

    • Yes, it is a bug.
      It was never implemented that way that clicking on it opening the toolbar.
      But it should do it if you click on it.
      So need to fix it.

      Thanks for the report

    • Great!
      The UI is already upgraded from v4.
      What do you expect exactly?
      Can I ask what is the most useful feature for you that helps your productivity?

      Thanks for your feedback!

  7. hello, i just upgraded to the paid version. how can I use the smart dark mode. or, how can i check if i’m using it?

    thank you so much in advance

    • Hello, you first need to enable the button in the toolbar.
      To do it, right-click on the WIndowTop icon in the tray and then Settings–>All Settings.
      In the window that opened, select the toolbar icon.
      There you will see a list of buttons that you can enable/disable.
      Find the “Dark-Dark” option and enable it.
      Now you should have the button enabled.

      Open the toolbar on some windows and you will see the new button.
      When you click on the button, dark mode will be activated.
      You will also see the option “Filter Images”. This option is unchecked by default and will work only on premium mode.
      To enable the “Smart dark mode”, just click on this option.

      If you have more questions/issues, feel free to ask.
