Look in Gimp menu Edit -> Preferences -> Folders -> Scripts (for example) which shows the location of the Gimp 2.10 user folder. In a standard Windows installation it is:-
C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\...
That is a Windows 'hidden folder' see:
https://support.microsoft.com/en-us/help...windows-10
Much is different in the Gimp scripts & plugins code but Gimp 2.10 runs in a 'legacy' mode so your Gimp 2.8 scripts and plugins will generally work.
The old registry.gimp.org site has been closed for a long time now, although often referenced in old Gimp web pages. There is a archive here:

Some of the old scripts have been updated here:

If you want a good Gimp 2.10 manual (English or Italian) in PDF format:

Otherwise, if you can not find a script/plugin, just ask. There might be a newer better equivalent.

Reminded me to recommend a modern plugin that comes with 500+ filters of all sorts, plenty of effects like that.
http://www.gmic.eu There is an installer, just use that.
