Command line to force a Windows Update check

Posted by Mike400

I have a small number of machines that will be off most of the time, but when the user turns them on and logs in I want to accept a script to perform a Windows Update using the default settings you would get if you click the "Cheque for updates" button.  This includes checking and installing any updates.

Note: The solution CANNOT crave admin privs.

  • Could you lot run a bat file from the run part of HKLM?

    wuauclt /detectnow

    or something like this PowerShell script?

    You lot could endeavor one of the UsoClient.exe switches - although I oasis't had luck with them.

    Adam, will the detectNow() also install or is there a different command needed to install?  I tin can't seem to observe the documentation on the Microsoft.Update namespace or class.

    I have my users trained to restart their PCs at the end of the twenty-four hours.  In this case just doing the shutdown will be sufficient every bit the install will proceed on the next power up.

    How are you triggering these updates? I don't run across why you couldn't avoid your admin issues if you just utilize the task scheduler and run tasks as system.

  • To kick off updates on Win ten, I utilize a batch file that contains this:

    start ms-settings:windowsupdate-activity

    Works for me, your mileage may vary.  Might also piece of work well from the Task Scheduler with 'starts at login' trigger.

    Nosotros do this via GPO. Download and install in one step. piece of cake going.
    For Upgrades like 21H1 etc... i moved away from WSUS and utilize a small batch file:

    Works great.

    If you're using an internal update manager similar WSUS you lot can set a deadline for install: if the machine is by that bespeak it will install the updates and prompt for a reboot. Adam (AJ Tek)​ should exist able to confirm, but this has been my experience.

    If you lot're just pulling from Microsoft, yous may exist able to implement something like through GPO.

    You could easily change the -AutoReboot flag to -IgnoreReboot.

    To automate information technology set up it upwards as a scheduled task that runs in the system context someday there is a logon or startup event on your laptop.  Then you don't demand to input any credentials.

  • Before we purchased an actual patch management program, we used to use a .bat file we would periodically run after logging into a machine.

    Technically, there were two, but the commencement simply copied the needed files for the second i to run.
    The first batch file only needs to be run once per machine.
    The second batch file needs to be run every time you lot desire to update each machine.

    I'm adequately certain this requires admin rights, but thought I would put it out here in instance it might aid spark something else for you.

    "Because you lot never know!"

    This is the windows retentiveness diagnostic program... non sure what this has to do with windows updates, but the title of the task is update scheduler.??

    I've been looking for a mode to remotely trigger windows updates, even check for updates from microsoft, but I'm non sure how this fits into that...?

    If there is something I've missed well-nigh the memory diagnostic programme, please let me know if you tin get it to work for you.

    Beside PSWindowsupdate doesn't install featured updates similar the 21H2 updates, in that location is a way to download both "normal security updates" and featured updates?

    That's besides possible with WSUS - the rolling deadline - problem is that it doesn't utilise here - considering the rolling deadline wouldn't be hit until the next time the system boots.

    As well, enabling WUfB policies and using WSUS will create a dual scan scenario, negating the fact that you're using WSUS.
