My laptop keeps nagging me to update to Windows 10.

I've resisted thus far, and now it's outright strongarming me in its newest popup: Would you update NOW or in four hours? Huh? Huh? Would you like that green eggs and ham HERE or THERE?

So, if I go through with this update, will I find I like it, I like it Sam-I-Am? Or will I regret it? I don't want to lose my precious bookmarks, okay?
