WindowTop is FREE, However, you will not get the best from the free version!

The PRO version includes what we call “Pro Features” which will be released over time to people who have the PRO version. WindowTop PRO is being purchased by hundreds of people for its advanced Features:

Save window configuration, so no need for example to set window on top manually each time
A better dark mode – see example below
Smart transparency (Opacity Pro) – see example down below
Shrink live preview (Shrink Pro) – see example down below
Shrink right click menu – see example down below
Add window to blacklist/whitelist
Eligibility to commercial environment (unlike the free edition)

What’s included in the PRO version?

Watch videos/windows in small view-box while you do your work. You can shrink window and enable for it live preview by right click on the shrink box and select “Enable live preview”.

Get a bigger preview of the window content when the mouse is above the shrink-box, and even enable transparency effect with click-through enabled

Work on your stuff while you see its results behind using exclusive transparency effect! (* Windows 10 Only)
No need to manually enable every time some feature to the selected window. For example, you can set window on top one time and then WindowTop will automatically set it on top for you when you open the window again

    • 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.
