M18 R2 windows 10 install

Hello Guys

I have steadfastly stuck to windows 7 on my machine but had to do a clean install yesterday and now windows update wont work. It just constantly searches for updates but never finds any. I have even left it running all day with the same result. I assume that windows have screwed with it to "encourage" users to switch to 10.

Anyway before I do switch to 10 is there anything I need to be aware of please? I am on 7970s..

Cheers for the pointers..
