Windows 10 Update Fails error code 0xc1900208

It seems Windows 10 Update fails sometimes, especially with the Fall Creators Update.  It continuously wants to install, you approve, it runs, and fails, often with error code 0xc1900208.   

In troubleshooting I have found most of the time it will install if you click the “Update now” button form the Creators Update Web page.  It seems to check for compatibility, make any adjustments, then Install.https://www.microsoft.com/en-us/software-download/windows10 

Should that fail to work, you can download the Windows 10 Update Troubleshooter, which will troubleshoot, and offer to repair any issues found.  There is also a troubleshooter for Win  7 and 8.https://support.microsoft.com/en-us/help/4027322/windows-update-troubleshooter 

However, I also recently read about an issue with attached USB drives oddly causing the update to fail.  Recently,  on a PC on which I tried all of the aforementioned options, and had no attached USB devices, I discovered a DVD in the drive.  Once ejected the update installed without a problem.  This strikes me as very bizarre, but perhaps the update searches other available drives for some reason. 

Therefore; I recommend if having issues with Windows updates, try disconnecting any USB devices such as external drives, thumb drives, phones which may be charging, and possibly even USB printers, and don’t forget to check the DVD tray, just in case.

Adobe Strange Characters

Have you ever opened an Adobe document and been surprised to see hieroglyphic-like, unrecognizable,  characters?

Adobe garble

Having seen this a few times and having found dozens of solutions on the internet, some of which seem rather complex, I did a little tinkering.  It seems the common denominator is one simple change; allowing “document fonts”.   I confess I have not run across this with Adobe Acrobat Reader, but if Adobe Standard or Pro, there will be an Adobe “Printer”.  To resolve the problem……….

 

  • Windows 7/8: Open Control Panel and then Devices and Printers Right click on the Adobe “printer” and choose Printer properties.
  • Windows 10: In the Cortana Search box type printers and click enter, which should open the Printers and Scanners window. Click on the Adobe “printer” and 3 buttons should appear, click manage, then Printer Properties
  • Click the “Preferences” button near the bottom
  • Choose the “Adobe PDF Settings” tab
  • Uncheck the box “rely on system fonts only, do not use document fonts”
  • Click Apply, OK, and close all windows
  • This requires a restart to take effect.

 

 

C:\Windows\Temp filling with .cab files

On several systems over the past year I have seen the C:\Windows\Temp folder filling up with large .cab files generated by the system, on a semi-regular bases.  This continues until there is no available drive space and the system becomes unusable.

The short term solution is to just delete all of the files but the problem returns after weeks or months, depending on the initial free drive space.

It seems this is caused by a large log file within the C:\Windows\Logs\CBS folder.  To resolve I created a folder C:\Windows\Logs\CBS_Archive and moved all  CbsPersist_file_number.log files, older than 10 days, to the archive folder.  This seems to have resolved the issue.

15 Minute Beeps

I was asked to look into a beeping in a server room which no one could find. 

It was understandably difficult as there were three server racks with modems, routers, switches, servers, PCs, UPSs, CCTV, and audio equipment.  To add to that they were single beeps, quite wide spread apart, and within a noisy, concrete room.  I determine after a little while they were single beeps and exactly 15 minutes apart.  Typically first suspicions are the UPS units, but 15 minutes is not typical of APC UPS devices.  To make a long story short, it turns out in a far corner where 2 fiber internet connections entered there were small UPSs units supplied by the service provider.  One of the UPS units showed a failed battery.  Being behind the open steel door, no one had seen the light. 

This seems like a trivial post and an obvious solution but I am posting as there are many forums on the Internet with people not being able to locate a device creating a beep every 15 minutes.  This is common with FIOS, Verizon, and Bell equipment.  One story goes as far as to explain a fellow turning everything off in the server room, one device at a time, every 15 minutes, till everything was shut down and unplugged, but could still hear the beeps.

.NET 3.5 & .NET 2.0 on Win 10

There are numerous 3rd party applications that require .NET 3.5 and/or .NET 2.0 such as QuickBooks, Profile, and more.  Normally you simply go to: Control Panel, Programs and Features, Turn Windows Features On and Off, select .NET Framework 3.5 (includes .NET 2.0 and 3.0) and install.

image

However with Windows 10 it will want to “Download files from Windows Update” and then fail, primarily when joined to a domain that has WSUS (Windows Server Update Services) enabled, resulting in an Error code: 0x800F081F.

image

The problem also exists on Windows 8 and 8.1, with numerous suggestions to resolve including removing specific updates.  These updates do not exist on Win 10, but if they relate to your problem see: http://www.askvg.com/fix-0x800f0906-and-0x800f081f-error-messages-while-installing-net-framework-3-5-in-windows-8/

To give credit where credit is due, Microsoft’s solutions to the Windows 10 problem are outlined in the following article: https://support.microsoft.com/en-us/kb/2734782

From that I was able to resolve using the following steps. :

  • Attach a Windows 10 install ISO, either by inserting the install CD, USB, or a path to an ISO file on the network.  The latter can be achieved by using the USB/ISO creation tool which downloads the files from Microsoft and creates the ISO from Microsoft: https://www.microsoft.com/en-us/software-download/windows10
  • If you are using an ISO file you can mount it so that it can be accessed using a drive letter within Windows 8/10 by highlighting the ISO file and choose manage then mount, from the menu bar in Windows Explorer.
  • Edit local group policy to look for your ISO when Microsoft Update cannot be accessed.  Open group Policy by entering  gpedit.msc  in the search box or from an elevated command line.
  • Locate the following policy: Computer Configuration | Administrative Templates | System
  • In the right hand window, scroll down past the folders and locate the specific policy: “Specify settings for optional component installation and component repair”.
  • image
  • Double click on the policy to open it, click the radio button “Enable”, and in the box “Alternate source path” enter the path to the necessary files.  They are located in the \sources\sxs folder of the ISO.  In my case this would be E:\sources\sxs
  • Note: there is an option in the policy to “contact Windows Update directly” but this did not work for me or others.
  • Force group policy to update by rebooting or from an elevated command prompt enter   gpupdate  /force
  • Now you can return to: Control Panel, Programs and Features, Turn Windows Features On and Off, select “.NET Framework 3.5 (includes .NET 2.0 and 3.0)” and install.  It should locate the files and install without a problem.
  • I recommend a reboot after doing so.
NOTE:  WINDOWS 10

–  I recently had difficulties applying this method to a Windows 10 machine.  I believe it may be related to it being an upgrade from 8.1, but I had to download the Windows 10 trial .ISO file from TechNet, mount it, and run the following command from an elevated command prompt.  (Substitute your drive letter for ‘D:’, and path if necessary)

dism /online /add-package /packagepath:E:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab

Unable to Print from Internet Explorer

I have had 2 clients unable to print from Internet Explorer 11 during the past month.  After some digging it seems there is a temp folder used in the printing process. 

C:\Users\%UserName%\AppData\Local\Temp\Low

This folder had no changes for several months and had a corrupt user ID (SID) within the security permissions.  Adding the user account to the security (NTFS) permissions of this folder and granting them “Full Control” resolved the issue.  A reboot is required.

I should have tracked down sooner as when printing, the page was blank with only C:///C:/Users/%UserName%/AppData/Local/Temp/Low/<random doc name>.htm printed at the bottom

The Mailbox has been Quarantined

I recently came a cross issue with an Exchange server running out of room and after the cleanup, one user only, would receive the message; “Cannot open your default e-mail folders.  Microsoft Exchange is not available.  Either there are network problems or the Exchange server is down for maintenance.”

image

The same user could also not log into Outlook Web Access.  After verifying DNS was working correctly, and then reviewing the server’s Event Viewer Application  logs at the time of the failure, a MSExchangeIS error with Sevent ID 10018 was noted.  “The mailbox for user 10c98e9d-1bcb-441c-a5bc-1a3fa19336f8: /o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=John Doe has been quarantined. Access to this mailbox will be restricted to administrative logons for the next 6 hours.”

image

The Microsoft articles listed below reference this issue and how to resolve.  Assuming there is no corruption with the mailbox you can verify there is a quarantined mailbox by viewing and simply deleting the registry key under:  HKLMSYSTEMCurrentControlSetServicesMSExchangeIS<Server Name>Private-{db guid}QuarantinedMailboxes

I recommend, as always, backing up the registry before doing so.  Then to apply the change restart the Microsoft Exchange Information Store service.

Virtual Machine Management Service failure

I recently came across a Hyper-V host which after a power outage and a dirty shut  down, due the absence of a UPS, could not connect to the Virtual Machine Management Service.  When opening the Hyper-v console the VMs were not listed, and selecting “Connect to Server” resulted in the following error message; “An error occurred while attempting to connect to server ‘ServerName’.  Check that the Virtual Machine Service is running and that you are authorized to connect to the server.”

image

The Hyper-V services displayed running in the Services management console, and permissions had not changed, however when checking for dependencies for the Hyper-V Virtual Management Service it show no dependencies.  Comparing this to another Hyper-V host reveals the service depends on the Remote Procedure Call (RPC) and Windows Management Instrumentation service. Both of these were running as well.

When services and system information is not present in various consoles, and the WMI service is running, it can often be a result of missing or corrupt WMI files.  You can confirm this by running msinfo32.exe (System Information).  If so, you will receive a message “Can’t collect Information.  Cannot access the Windows Management Instrumentation software.  Windows Management files may be moved or missing.”

image

If this is the case there is an easy fix:

  • Always have a full backup of your system before making any changes!
  • Note:  Microsoft recommends troubleshooting, and restoring the WMI files rather than deleting them as I describe here.  Deleting the files can affect 3rd party software which may require reinstalling.  For more information see the links at the end of this article.  In this case the WMI checks showed no inconsistencies and a reset failed, so rebuilding was the best option.
  • Stop the Windows Management Instrumentation service, which will warn you that it will also stop the Hyper-V Virtual Machine Management and other services, verifying the link between the two.
  • Rename the WMI information file folder to something such as .old  C:\Windows\System32\wbem\Repository.old
  • image
  • Restart the host.   Upon reboot it will recreate the Repository folder and its contents.  You may find the first logon hangs for a few minutes and also it may be slow for a while as it rebuilds the files.
