I have Windows 7 64-bit and the Windows Update isn't working properly. What can I do?
I've found that sometimes you just have to wait, but if it takes a significantly long time try the following:
Almost went crazy trying to fix this. The problem is that there wasn't a problem at all.
Yes you heard it. Even though it said 0% downloaded, it was downloading all the time. There were too many updates available to be downloaded to be computed and shown. Just have patience and leave it to do its work.
If you want assurance that it is working, click on the Windows symbol at the bottom left, now look at the "Shut Down", see the little icon beside it that shows that it will shut down after it installs the updates that you have downloaded.
Plus if you have the patience and leave it, you will see that after a while, 30-40 minutes for me, the details will then change to say, installing updates... Bingo!
I've had the 0kb 0% problem for a while, and I have tried everything including completely restoring my laptop to factory settings, but it turns out that the only thing that was broken was the 0kb 0% text, if you click install updates, then every so often look at the size of the software distribution folder, and if the size changes then you will know that it is downloading the updates, around an hour and a half later (I had 109 updates) it started installing all the updates.
So to fix:
1) click update
2) monitor the size of the SoftwareDistribution folder to see if the size changes
Also Checking the dates of the updates is also an indicator that you are getting more recent updates.
3) wait at least an hour (depending on how many updates you have), and hopefully it should start installing the updates (and it will say on the Windows Update windows " Installing update xyz "
Example: It may also say for example, Downloading 66 updates (386.5 MB total, 57% complete)
4) restart computer if said after installing updates.
This happens if Windows has already started downloading and installing updates on its own. The foreground process just sits there waiting for something. I guess either the foreground process is waiting for a lock held by the background process, or the background process is too busy to communicate to the foreground process. If there are many updates, e.g. it's a fresh install or the system has been offline for months, it takes hours to download and install the updates, and until the background process in the the right mood, there is no progress shown, there are still 0% of 0KB downloaded. Eventually, the download progress starts showing reasonable numbers, just be patient. Please don't assume that nothing is being downloaded - it's just not being reported by the foreground process.

I also struggled with this problem on my new Acer Aspire Switch 10 tablet that come with the preinstalled Windows 8.1. The tablet was manufactured in March 2015 and had a few KB updates preinstalled by that time, but I bought the tablet in November 2015 so I decided to install at least all missing critical system updates.
I could install only updates for the Windows Defender, but all other updates hung on "0% percent download". All recipes posted in this discussion thread did not help. When I started to investigate the problem, I found that I need to install the KB2919355 first. According to the accompanying description in the Windows Update center, this update should eliminate problems with getting and installing future updates.
However, it was not an easy task to install that update. It failed when I tried to install it the normal way. I downloaded it as a standalone .msu install package to my HDD and tried to install it this way, but no luck again. The event viewer showed me that the installation failed with the error code 0x8E5E03FA. Finally I found a solution of this problem here:
Here is a copy of the solution in the case the referenced article will disappear:
I did that, and then managed to install the KB2919355 update. After that, I could install all other missing critical updates through the Windows Update applet in the Control panel.
