New HDD--fresh install win 7---won't update

It did happen to me too and after installed this update: https://support.microsoft.com/en-us/kb/3102810, it solved the issue. FYI I'm using windows 7 SP1.

After days of attempting solutions to a zero percent appearing on downloads on Windows Update (Win 7 Pro), the light came on in my brain. It is taking hours to accomplish a task that used to take minutes. What have I not done to accommodate this? Click Start; in the Search box type the word sleep. Change the "Put the computer to sleep" to "Never." Why? Because now your machine will have enough time to do the updates. (I used to leave it on overnight in update mode, but failed to realize it would quit in 30 minutes and never get the job done.) I hope this simple solution works for you. (Try not to hit yourself too hard on the forehead as you say "Duh." My bruise should subside any day now . . . )

I myself had this same problem 3 times.
Last week I've installed Win 7 on a laptop. WU has searched for hours and nothing. I've turned it off and on the following morning it found all the updates to install in minutes.
I think MS shuts down the server for maintenance once in a while.

I'm still not able to update. I wanted to upgrade to 10 but it won't unless 7 is current with updates.

I think you are going to regret. Win 7 is a better OS.
Nothing better like a fresh install.
- Backup all your data on another drive.
- Make a installation USB with Win 10.
- Boot on the USB with Win 10.
- When asked just furnish the Win 7 Key. It will install and register.
