Build 1607 in Windows 10 update is S L O W. Why they did such a huge update, and so many all at once, I'll never know. I forgot about update Tuesday. Then I see it is vital you get the updates asap. I looked and I was only downloaded at 49%. I thought it was stuck, as it didn't go anywhere in a majorly long time. So I restarted. Some updates were ready to install. I noticed it was downloading KB3189866. It is at 45%, and has been for a very long time. I am concerned now. I hope this is not going to be a sign of the times to come. I am afraid to restart after this bad boy finally downloads...if it ever does. My modem isn't even blinking to show there is anything going on. This is the slowest update I've ever seen. Anyone else seeing this? If this messes up my computer, I am going to be VERY UNHAPPY.
