Badly. But depends on your usecases.

Generally - java plugin is dead. Deal with it. Me, as itw developer is sad, but me ITW maintainer is 
happy. And me as web user is double happy.

So why do you wont to dig it out of grave?

ITW was never supported on windows. There is fork of ITW for windows (have also Windows plugin) 
which I.m aware it exists, but I never seen it. it is created by local guy Jacob (cced).


javaws part of ITW, although not supported on windows, is known to work on windows. (Jacob tested it 
and send many patches to enhance compatibility). There is no real reason javaws shoudl not run on 
your machine.
As addition ITW's javws have nice feature - javaws --html somePage - It can run applets on this page 
without browser. But by general concept (you can not do browser app was designed  without browser, 
right?) its powers are limited. Still it will be soon the only way how to run legacy appelts (once 
browsers finally cut off npapi)

Sorry for bad news
