    • 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).
