Poopy extended, slightly modified:
WIN11: Make sure you have already downloaded the mouse pointers you like. You need to know where the transparent cursor files are on the internal memory, they can be put into the the same folder like all other cursors (C:\Windows\Cursors).
If you have a windows pc that is up to date go to the mouse settings, scroll down until you see additional mouse settings, click will open a window. When the window opens you will see options at the top. Click POINTERS. Then all the icons for each pointer reaction will show up. Click the pointer you want to change and click browse. Insert "transp" into the file field to filter, then click select the replacement from the displayed transparent_*.cur file names below. Klick APPLY, then click OK. Keep a folder with icon view open showing the replacement files and their names for visual verification.
