I guess the slipstream 10 didn't take
Strange, it works for me.
Still 12 updates ain't bad. Did you run the one on the C drive and then nf4.5 slim installer ?
If you do that and then restart - you won't be offered nf4.0.
There is no point including MSRT or windows defender as they update so often. It will offer a couple of other thigs you don't want like Bing Desktop and silverlight as well. Just hide them.
Yandex is the most popular after google ( not including Baidu - which is Chinese ).
