You're multitasking with several windows but want to anchor a specific window on your Desktop for convenience. In this guide by SoftwareTricks.com, we'll show you how to keep a Windows working window always on top, pinning windows on Desktop.

1. Utilize DiskPins Software
To use the software, visit the following link to download and install it: https://deskpins.en.softonic.com/
After installation, a software icon will appear on the Taskbar tray.

To pin a window, follow these steps: Click on the icon on the Taskbar -> the cursor will change to a pin, click on the window you want to pin to the top.
Then, a red pin icon will appear on the window title bar, making it easy for you to identify which windows are pinned.

To unpin a window, hover over the pin icon, the cursor will display an 'X', indicating that you can unpin the window.

Alternatively, if you wish to remove all pinned windows, hover over the Taskbar icon -> right-click and select Remove all pins.

2. AutoHokey Software
You can also create your own script to set a specific shortcut key for pinning a certain window always on top of others.
You can visit the software's homepage to download and install: https://www.autohotkey.com/download/ahk-install.exe
Step 1: Move your mouse cursor outside the Desktop then right-click and select New -> choose AutoHotkey Script.

Step 2: Right-click on the newly created File and select Edit Script.

Step 3: Then type the command:
^Hotkey:: Winset, Alwaysontop, , A
Then close the window and select Save.
As in the example below, I'll set the Hotkey to be the spacebar (Space).

Step 4: Then double-click on that AutoHotkey file, now you'll see a green H icon appear in the Taskbar tray. This indicates that the software is active.

Step 5: Now to pin the application window, open the application window on top, then press Ctrl + Hotkey (As in my example, it's Ctrl + Space) When you do that, the window will be pinned to the Desktop.
To disable the pinning mode, simply select the window and then press Ctrl + Hotkey again.
Wishing you all success!!!
