This is a very strange issue. I've had a tablet for a week now (Acer Iconia W700-6670) and I want to do the Windows Updates but they just don't seem to work. As in the updates are still in WU like they weren't done at all. I've done them three times now and I don't want to do them again because it's f**king long. The updates work fine on my other stuff so why not on the tab? And Windows Update itself seems to have connection problems. It seems that it only downloads whenever it feels like it. All it does is take some CPU power without downloading anything. Literally, not downloading anything for a while, then it does for 5 seconds, and then just stops for another while. But that's something that happens in all versions that I have (my PC, a Laptop, and the tablet).
