  • Install without check

    • I have 3 separate environments that I update, development, QA, and production. These are kept to the same patch level but are done on different days so that the change can be vetted first. It would be nice if the install just installed what had been downloaded. That way I could make sure that they all had the exact same patches available to be installed.
  • Time off by one hour for get-wuhistory
    1 Posts | Last post February 17, 2016
    • The isntallation date/time in list of installed updates generated by get-wuhistory seems to be one hour off. Could be related to timezone? Is this a bug? Is there a way to make it list the correct time? I'm at GMT+1 or (UTC+01:00) Brussels, Copenhagen, Madrid, Paris. Daylight saving times starts on 27 march.
      So for example date is listed as: 17/02/2016 1:47:18 while it should in fact be 17/02/2016 2:47:18.
  • Get update PUBLISHED/RELEASE date

    • I am using the command "Get-WUInstall -MicrosoftUpdate" but was wondering if there is a way to get the published date of the KBs?  This would be very helpful.
      Thank you

    • Hi, what ports /services should be open for Get-WUList work against remote server with Firewall Enabled
      Getting this error :
      Exception calling "CreateInstance" with "1" argument(s): "Retrieving the COM class factory for remote component with CLSID {4CB43D7F-7EEE-4906-8698-60DA1
      C38F2FE} from machine srv* failed due to the following error: 800706ba srv*."
      The following ports and exceptions must be added to the Windows firewall settings for Windows Vista and Windows Server 2008 for the WUA API to be called remotely.
      Exception 1
      Local port: 135
      Remote port: ALL
      Protocol number: 6
      Executable: %windir%\system32\svchost.exe
      Service: rpcss
      Remote privilege: Administrator
      Exception 2
      Local port: Dynamic RPC
      Remote port: ALL
      Protocol number: 6
      Executable: %windir%\system32\dllhost.exe

  • Specific updates?

    • Hi Michael.
      I have been using this amazing tool for a while. I would like to pull a certain list of updates by KB name from the MS site. Is there a way to incorporate the list into the script?
  • Is this the most reliable PowerShell command to Export List of All Windows and Software Updates in Windows 10?

    • Hi,
      I'm a newbie to PowerShell but in my first hours I have made list of all Windows and Software Updates installed on my pc. It's not perfect like HTML file list of installed Windows updates by using wmic command.
      I tried next:
      1. Get-WUHistory >D:\WUHistory.txt followed by 2nd command
      Get-WUList >D:\WUList.txt
      2. In this case (on D: drive) with only this 2 files, I've applied:
      copy wulist.txt + wuhistory.txt AIOupdates.txt
      copy *.txt AIOupdates.txt /a (if other txt files exist they will be also added!)
      Both files are added into one file. To search for a particular KB I use Notepad++.
      However this list includes all entries of successful and unsuccessful (updates and drivers) installations via Windows Update.
      I noticed that Micorsoft use same KB ID for all versions of Windows Defender update Definitions what results in multiple entries:
      KB2267602 (Definition 1.213.1863.0)
      KB2267602 (Definition 1.213.1837.0)
      KB2267602 (Definition 1.213.1574.0)
      KB2267602 (Definition 1.213.1541.0)  
      Therefore this list doesn't serve a purpose.
      3. Another command which I have applied is:
      Get-WUList -MicrosoftUpdate -isinstalled -computername <pcname> > d:\msupdates.txt
      This is much better solution without duplicate KB IDs (as produced under the step 1.). So, my question is: Is this the most reliable PowerShell command to Export List of All Windows and Software Updates that are installed by using Windows Update (in Windows 10)?
      Many thanks for this update!
  • Date update was released

    • Is there any option to query the date of when an update was released?
  • Patch for Optional Updates

    • if you want to see optional updates in the list, use this patch:
      I could not figure it out yet, why BrowseOnly = 1 does not work in the search criteria.
  • Not work in Windows 10

    • Okay, so use with Windows 8.1 and works perfect, but does not work in Windows 10. Soon for Windows 10? Thousand thanks.
    • Not sure if you had it pre-installed when you updated to Windows 10, but I have no issues running the PSUpdate Module in Windows 10.
    • *Forgets one detail*: If you had the home edition of Windows 8.1 when you tried going for Windows 10, then it's possible you may not be able to run the module to full capacity as it will self-manage the updates automatically and no regedit entry would be able to disable the Windows Update service.
  • Get-WUList with -Microsoft parameter throws out warning message
    3 Posts | Last post December 03, 2015
    • Hi,
      I'm trying to run the command Get-WUList -MicrosoftUpdate -Computername 
      It gives a warning message
      WARNING: Can't find registered service Microsoft Update. Use Get-WUServiceManager to get registered service.
      Get-WUServiceManager shows the following so Microsoft Update is registered on the remote computer
      IsManaged IsDefault Name
      --------- --------- ----
      False     False     Windows Update
      False     True      Microsoft Update
      Would do I need to do for the command to run successfully using the -Microsoft switch ? It does run fine with the WindowsUpdate switch but this does not always list all the outstanding patches. 
      Many Thanks !
    • I should have mentioned I'm trying to do this to a remote machine on the same network
    • 1°) On your Windows 2012 server search for "Windows Update Settings".
      2°) Click on "Choose how updates get installed"
      3°) Check "Give me updates for other Microsoft products when I update Windows"
