Installing new patches? (edit: patterns)

[Joe]

Searched through this forum without success, as I am NOT an advanced pc computer person by any means.  Purchased a new pc, its been updated to windows 11.  Downloaded Gimp 3.0.  The old machine croaked and took my personal patch collection with it.  I've been searching and searching for a method to install new ones without success.  Frankly, I can't even get windows in its infinite wisdom, to allow me to even locate the folders, where I believe new patches would reside in Gimp.  Anyone know where there's a relatively SIMPLE tutorial to install new patches?  Was hoping there was a tutorial to install them utilizing Gimp, and not cracking the mysterious codes within the Gimp files scenario via windows.  For your consideration - I thank you.
