I have a Lenovo Laptop with Windows 10, and I am on a very, very slow Hughesnet connection.  (12kbs not kidding)  The problem is, when Windows 10 decides to update it takes FOREVER and I can't do anything else with my computer while it is downloading.  It has been stuck at 47% download for the last 6 hours, and I can't find a way to cancel it out.  It look 5 minutes for my aol email account to LOAD up.  Is there a way to cancel the download and time it for later in the evening?  Thanks Isn't there any option related to Cancel Download or you can just restart the system? Well, I don't think there is a way. unlike the previous versions of windows, windows 10 doesn't give user to cancel UPDATES or select which updates should be installed. The only solution to reverting back to previous versions of windows or you can wait it out (leave your PC on overnight).  Hope I could help.

I did check out the hyperlink provided by Allan, and unfortunately, at this location, I have to use Ethernet and for the Windows 10 Home version you couldn't tweak it as can be done for the other Win 10 versions.  If I had Win 10 Pro or better I could have done it for either WiFi or Ethernet.

Thank you all for your input.  It is very much appreciated.
