Hello
I have a Windows 10 Pro (v.1511 - x64) PC, whereby in the "Update & Security" window it shows that updates are available, for example "Definition update for Windows Defender", "Security update for ASP.NET..." and so on, but it does not download the update at any point in time. The power options have been changed to make the PC stay awake 24/24.

Any fix for this issue?

Thanks...

Let me share I don't fret about this unless it goes on for about a month. Also, any competing security app could interfere with Defender so for now my advice is not fret and wait it out.

You may have done this but often I find a reboot or two resolves this type of issue for me. Open up Settings > Windows Update and click Check for updates, wait for it to finish, then reboot. Do this twice and it is likely to clear up, otherwise it may just be something that takes longer to download. If it does go on for longer then you may have a more serious issue indeed.

It is possible that your connection somehow got switched to "metered". If set to metered, downloads are deferred, although for how long I am not sure. I've attached a script (vbs) that you can execute to get a connection's metered/non-metered status and set it to one state or the other.

At home I have a 160 gig/month connection but at the cottage I have a cap of 3 gig/month so I set the cottage connection to metered to defer the download of updates.

'
'   Description:
'
'       Command line utility to set an internet connection to metered
'       or non-metered
'
'   Usage:
'
'       metered
'
'           Show existing profiles
'
'       metered <profile>
'
'           Show metered/non-metered status of <profile>
'
'       metered <profile> ON | OFF
'
'           Set metered status of <profile> to on or off
'
'   Notes:
'
'       The default engine for running scripts is wscript.exe. Before
'       running this script you should set the default engine to cscript.exe
'       (command line - wscript is windowed). Open a command shell as
'       Administrator and enter:
'
'           cscript //nologo //h:cscript //s
'
'       You will only have to do this once.

Hello
I've tried all of the proposed solutions, but still it keeps showing the updates, without downloading anything thou. Any other solution which might help out (except from a format re-install)?

Thanks.

There is the old method worth knowing about. Find the KBnnnnnnn (the n's are the number of the KB) then google that KB number. Many of these have manual downloads and installers.

Worth noting are those cracked and crack activated Windows. These are known to fail WU (Windows Update.) Be sure you know your OS condition. That is, no cracks, not infected.

Thanks for this tip rproffitt, managed to get it to update from this by downloading from the Microsoft Update Catalog

commented: Thanks for trying that. Comment about it below. +12

Thanks for the update. Be aware that most of these are not urgent and important. Some will fail and the telemetry back to Microsoft shows it failing which if high enough tells Microsoft there is a problem.

Forcing the install can in extreme cases cause systems to stop working. This is why I suggest being sure of the Windows OS's state (no trojans, etc.), enough free disk space and so on. Patience is best and check on it in a few weeks.
