In collaboration with Sweezy Cursors, Opera GX and Sweezy now offer a library of over 30 cursor packs – including both static and animated designs – that can be applied with a single click.

So better way to retrieve animated cursors from windows is to go to Control Panel, click on add/remove programs, then click windows setup, Then install the desctop themes.

The optional KB5050094 patch for Windows 11 was supposed to fix stuff, but introduced problems of its own with the mouse cursor, File Explorer, and more.
