Does Windows auto-update always run regardless?

By Healer ·
I always have a feeling that the Windows auto-update be it any edition still runs in the background as long as the computer is turned on and the Windows system is started. It does not matter whether an administrator has logged on. Moreover there would be no indication whether the process is running especially if the system is logged on by a non-administrator.

The reason I ask is finding some way to monitor the data download.

Depends on the Network involved

by OH Smeg In reply to Does Windows auto-update ...

If there is a WUS Server in use this pushes out the Updates to the Workstations.

If this is just a stand alone system that is connected to the net provided that the Windows Update is actually turned on it will run at the time specified.

If it is set to not check for Updates it doesn't run.

Log File

The update services leave a log file located here:
C:\windows\Windowsupdate.log

It tells you everything it does.

I just checked my Windows 7 system

by Healer In reply to Depends on the Network in ...

it sets by default the update be done at 3:00 am every day. I wonder if it would catch up when the computer turns on later. Do all editions of Windows behave the same in this respect?

Can I say the automatic Windows Update would be done anytime when it gets a chance even though it might not be logged on or logged on by a non-administrator?

Yes.

Well if the system is not on when the scheduled Check is supposed to happen that day it will wait till the next time that it's supposed to look.

Probably more importantly here is when you have your AV Product set to do a Scheduled Scan if the system is not turned on at that time it misses out and if there is an infection it's another day before it gets removed.

Do all editions of Windows behave the same in this respect?

Well with 7 It's on by Default where as XP had to be turned on.

But when they are on all act the same way.

Can I say the automatic Windows Update would be done anytime when it gets a chance even though it might not be logged on or logged on by a non-administrator?

Yes most defiantly.

If Windows Update is enabled (which you can disable unless forced by a policy, be it local or domain) and will download whenever it feels like it. Updates will only be installed at the designated time in Windows XP, unless dictated by the aforementioned policy.

I belive Vista and 7 will immediately install updates that will not require a reboot, which is a policy option in XP. I have Windows 7 and here is my log:

XP does not behave the same by default?

by Healer In reply to Correct

I am more concerned on the data download because I am required to pay for excess data download. So I set all my systems to check for the availability of update and notify but do not download until I ask to.
If set to auto-update, are you saying Vista and Windows 7 would download and install in the background as long as the computer is turned on without bothering the owner? Is there any indication on the task bar that the download or install process is underway even the computer is not logged on by an administrator?

Notify.

by seanferd In reply to XP does not behave the sa ...

Behaves as indicated - it will check for updates, but only notify you that they are available.

If bandwidth cost is a problem, just install critical updates. If you were to need updates after a reinstall, for instance, perhaps connect to a friend's network which does not have bandwidth metering. Normal updates should not be gigantic all the time, but the longer you wait, the bigger the backlog. And you don't want to catch something that could have been avoided by updating. For instance, what if the machine were infected with a trojan that runs a spam server from your machine? You'd get one hefty bill for overages then.

If you have changed it from the "Recommended Settings" then it will act as you have told it to. Is this for a business or just a bunch of PC's at home?

I have a few computers in a network at home and I am also supporting others in homes and businesses. We want to be able to control the data download as we pay for excesses.
