First thing, there is not yet a Windows installable Help for Gimp 2.10 - It is work in progress but depends on volunteers to create one.
The help system is very language dependent but assuming using the basic US-English version, the installer:
https://download.gimp.org/mirror/pub/gim...-setup.exe
If you install Gimp to the standard location, it should be picked up (1) but there is a complaint (2)
However, continue and it unpacks to the correct location (3)
That shows up here in Edit -> Preferences -> Help System (4) which you should check. Gimp built-in help browser works here but try your default browser as well. Gimp help is all html. F1 for help brings up the help browser (5)
Shift-F1 for context help depends on the tool, the old ones should work (6) but newer tools specific to Gimp 2.10 will not be there.
If you can not get local help to work, my advice is get the English version as a PDF here: http://gimp.linux.it/www/meta/ This is still Gimp 2.8 help, the PDF now has the index at the beginning and is searchable.
