------- Additional Comments From dank@kegel.com 2006-14-05 12:14 ------- And here's an article about how NT 4.0 does it: http://www.ddj.com/dept/windows/184416526 Still a 64K entry global table for all USER object in the system. (And apps are limited by default to 0x3000 entries in this table each.)
http://blogs.msdn.com/oldnewthing/archive/2005/02/15/372995.aspx mentions that win32k.sys might use global shared memory for some USER things, but I think it's only for callbacks, so it shouldn't affect us.
