Lol he say you do update windows, now your W7 will be slower than before without update
I have never update my W7 (disabled in service "Windows update" since Install W7 clean) and I can run LU without issue.
Maybe you miss Package Redistributable or other, I don't know I'm sorry don't help you so much but I'm here for say Update Windows is useless expect If you want make slower your Windows
Edit: I see your probleme is solved, right? sorry for up
