I tried uninstalling it, doesn't work even if you turn Windows Update off. It overrides your settings and changes them back to automatic as well if I saw it correctly. The ubergeeks say it's 900 MB in size, this patch and that's just obscene.
Some have noted that their older computers have become sluggish or no very useful, Meanwhile Google and Intel say Oh no, it's really groovy, no bad tripping. Both Firefox and IE 11 felt like they started rough and needed fueul system cleaner to me at first but maybe some of the Kinks are worked out now, but after 7 YEARS I'm wonder who was Passing The Dutchie.
